The Three Hats of VoIP

Over the past few years new VoIP products and services seem like they are announced daily. While this rate of innovation is exciting, it is also very confusing. How are these companies the same or different? What service should I use for my business?

These new VoIP solutions fall into one of three general categories: hosted PBX solutions, telephone API platforms or telephone applications.

Many hosted PBX solutions, such as Packet 8, Vonage or Fonality, replace your business’s premised based telephone with new SIP phones or “soft-phones” connected over the Internet to a hosted PBX system. These solutions often result in lower costs with no premise based telephone system to support and maintain. But, there are hidden costs in this model that complicate the buying decision. The best solutions require your company to install a dedicated, VoIP-optimized Internet connection. These connections are often more expensive than dedicated phone lines so some of the costs savings disappear. Since cost is most often the driver for the switch from plain old telephone lines (POTs) to hosted PBX solutions, this space has been commoditized and has become highly price competitive. This price competition is good news for your business but creates challenges for the hosted PBX companies.

Telephone APIs from companies such as Twilio and Voxeo, offer a platform where your software developer initiates and controls phone calls without purchasing equipment or telephone connectivity. The best APIs, such as Tropo from Voxeo, give your company access to a sophisticated, and highly reliable, telephony network suitable for developing complex telephone applications. Ease of use is often a selling point of these platforms, but in reality they are only easy to use for experienced software developers since they provide infrastructure and not packaged solutions. An experienced software developer may be able to code a simple phone call with just a few minutes of work using a telephone API. But building a robust, reliable telephone solution, such as dynamic call tracking, a virtual call center, or customer notifications service with retry logic and automated scheduling, requires hundreds or even thousands of hours of work. Telephone API solutions are best for companies where integration of telephone services is a core competency and where dedicated software developers are available for application support and maintenance.

Telephone application services are completely different from both hosted PBX solutions and telephone APIs. Telephone applications, from companies like Ifbyphone, provide your business with complete, ready-to-run, hosted applications that work with any telephone - business, home, VoIP or PSTN. The plug and play nature of telephone application services enable your business to measure value immediately - increased sales, reduced service delivery costs and improved customer retention. You can use these applications to manage, measure and automate phone calls that track advertising campaigns, dynamically route calls, provide customer notifications and deliver customer fulfillment or support via virtual call centers or distributed call groups. Then by utilizing an API on top of these applications your company can quickly and cost effectively integrate these ready to run applications with key business processes.

To further clarify the differences among these three VoIP models, let’s compare them to traditional web business services.

  • Hosted PBX solutions are like Internet backup services such as SugarSync or Mozy. Instead of purchasing and maintaining your own computer backup equipment, you back up your computers over the Internet to a centralized service. While you share a high-quality backup facility, you still carry the cost of the Internet connection and the desktop computers.
  • Telephone API platforms are like web hosting companies such as GoDaddy or Rackspace. The hosting company provides you a platform to build anything you want providing you have the right skills and the staff to support your custom application.
  • Telephone application services are like or NetSuite. While you could build your own CRM system, most businesses choose to use an off-the-shelf CRM solution. then provides APIs for integrating with their applications and a specialized environment for extending the platform ( Similarly, Ifbyphone offers an API for integrating with our applications.

While hosted PBX solutions, telephone APIs and telephone applications may share the VoIP “cloud”, these three solutions are very different. Think of hosted PBXs as replacements for existing telephone systems. Telephone API platforms provide a greenfield environment for software developers. And, telephone application companies, such as Ifbyphone, provide ready to use applications for businesses looking to increase sales, improve customer retention and increase business efficiency.

By focusing on ready to run telephone applications Ifbyphone is helping thousands of company manage, measure and automate voice interaction with hundreds of thousands of customers daily.

Early Adopters vs Mainstream Customers; Android vs iPhone

Since the iPhone 4 began shipping a couple of days ago I have read a multitude of articles comparing this new phone to various Android based devices, generally focused on the newer Droids. I think the authors writing these comparisons miss the point; these devices are serving very different marketplaces and therefore have developed completely difference ecosystems.

Reviews are often focused on processor speed, memory, camera specifications, battery life, size, weight, and the number of applications in the app stores. Some comparisons proceed to position the iPhone as a closed system and highlight the advantages of the open Android development environment. More complete reviews include Nokia and Rim devices in the mix. Almost all of these reviews focus on the devices and not the users of smart phones.

Back before smart phones, Geoffrey Moore in "Crossing the Chasm" described an evolution of product adoption that applies to many high tech companies. Moore's classification of customers is very similar to the technology adoption lifecycle developed by Joe Bohlen, George Beal and Everett Rogers in 1975. The lifecycle classifies customers into groups called innovators, early adopters, early majority, late majority and laggards.

Moore argues that companies need to focus on one group at a time to cross the chasm between the early adopters and mainstream customers included in the right-most customer group shown above. He continues to point out that many high tech failures occur after a company has amassed a significant number of innovators and early adopters but fails to understand the needs of mainstream customers.

Android is an early adopter ecosystem while IOS (iPhone) is for mainstream customers.

The open Android ecosystem provides developers with a highly flexible, open, and easy to root (gain operating system access) development and runtime environment. Google provides very few limitations on the applications available to Android users and does not restrict application distribution. In fact on the Android Market developers web page it states "Android Market is open to all Android application developers. Once registered, developers have complete control over when and how they make their applications available to users."

In contrast the IOS (iPhone) ecosystem is tightly controlled by Apple. All iPhones ship with a locked down application environment. If you "jailbreak" or unlock the application environment on your iPhone you invalidate your warranty. Developers are required to submit all applications to Apple for review and Apple has full authority over the applications it will allow developers to distribute via the App Store.

Given these differences why would anyone want an iPhone? Because most smart phone users are not developers and in fact do not want to take risks with their phones. They want the company that provided them with the phone to ensure a third party application will not break their ability to make and receive phone calls. Mainstream smart phone customers value consistency over creativity, reliability over flexibility and stability over openness. From the perspective of most iPhone customers there are more applications available in the app store then they will ever need.

Why do developers build applications for the restrictive iOS (iPhone) ecosystem? To paraphrase a famous campaign slogan from the 1992 United States Presidential election, "It's the economy stupid". The mainstream smart phone marketplace is vastly larger than the early adopter market and the Apple ecosystem provides developers with a very easy to use distribution channel.

In conclusion, both the Android and the IOS (iPhone) ecosystems provide valuable additions to the telecommunications world. Both solutions provide customers with vastly more choices and with hundreds of thousands of applications. Early adopters that value the maximum in flexibility and that are unfazed by some inconsistency between devices and applications will find their needs well served by a wide range of Android devices. Mainstream customers that want a smart phone that just works and still offers hundreds of thousands of applications, but may not always have the very latest application, will be delighted with an iPhone. When comparing products and services in the rapidly changing technology world of the 21st century, remember to first understand the customer demographics served by the product or service and then properly qualify your comments for a specific marketplace.

Thoughts About Clouds

My thoughts about the evolution of cloud computing and cloud telephony.

Let's begin by thinking about the history of computing. First we had mainframes, since they were very expensive we shared them, hence timesharing. Then as computers became smaller and more inexpensive we put mini-computers in our businesses, and ultimately personal computers on our desks. This lead to fat client, client server computing. Unfortunately we found that supporting complex applications on our employees desks was very expensive, so we began to move applications back to the data center and ultimately to the clouds.

The same evolution is occurring in telco. In the beginning of telco all complex components where centralized in central offices and switching stations. Then as PBX systems dropped in price, enterprises installed PBX systems, and ultimately many small businesses installed key systems. However, these systems were limited in their expansion capabilities and expensive to support, so business have begun to look for alternatives. The alternative is to move telco back into the clouds with your telephone becoming your voice and multi-media browser accessing cloud delivered services.

In the telco industry we have always lived in the clouds. I would propose that Cloud Computing is in fact just the latest terminology for Timesharing and in the world of telephony Cloud Telephony is in fact the latest evolution of "The Network is the System".

It is ironic that while traditional telco is the gold standard of quality and reliability, you probably remember 5 nines of reliability in the old days, cloud computing and cloud telephony are viewed as inherently less reliable. In fact it is just the current implementations that are not as reliable as they need to be.

To summarize I predict that in a place not to distant from today, your computers and telephones (often the same device) will be browsers for multi media content which will include voice, audio, video, images and text and that the "cloud" industries will resolve the reliability challenges.

Here at Ifbyphone we are leading this revolution by providing automated telephone applications that reside in the clouds and work on any telephone.

Ifbyphone Interview about Cloud Telephony with TMCnet Rich Tehrani

This interview between Irv Shapiro CEO of Ifbyphone and Rich Tehrani of TMCnet explains the Ifbyphone services and their integration into the telco ecosystem.

The Telephone Technology Pendulum and AnyPhone Technologies

Arthur Schopenhauer a German Philosopher, wrote an often misstated quotation, "Life swings like a pendulum backward and forward between pain and boredom".  We can apply this quotation in general to technology and specifically to telephony.  Telephony technology swings between complacency and advancement.  In these exciting times, when telephone technologies are rapidly advancing, we are often faced with the pain of innovation.

This pain is partially caused by the instability of change. Many of us have moved the majority of our telephone use from the over 100 year old, stable and reliable, plain old telephone service (POTS) to mobile and VOIP communitations. This pain is also partially caused by the transition of telephony from a hardware driven industry to a software industry with all of the advantages and shortcomings of software systems. Software, unlike hardware is relatively easy to change. This ease of change indirectly leads to reduced testing and an increase in software failures, commonly called bugs. With software innovation in the telephony industry the bugs in the system have increased. So next time you are walking down the street and your cell phone drops a call, recognize that this might be caused by a poor signal, an ineffective network design, limited cell capacity or even a plain old software bug.

As an entrepreneur I am happy to accept the pain of change over the boredom of stagnation. The next evolution of telephony, returns telephone services to their roots, it moves them into the clouds. Traditionally most people used telephone services connected to a centralized telephone utility. As networks expanded and became more sophisticated additional capabilities were added to the centralized utility.  In 1977 Julius Marcus, VP of Networks and Communications at Digital Equipment Corporation coined the phrase "The Network is the System".  This phrase, in various iterations, was later used by AT&T and Sun Microsystems.  With the development of Cloud Telephony, the network is the system.

Cloud Telephony provides hosted telephone services accessible from anywhere at any time.   However, many of the first Cloud Telephony services, such as hosted or virtual PBX solutions, still require dedicated specialized telephones.  This isn't limited to hosted PBX solutions.  In the United States, most of the cell phone carriers require telephones specifically configured for their networks.   So while cloud or network based telephone service are expanding our communications horizons, they are not freeing us from device dependence.

At Ifbyphone we are taking Cloud Telephony to the next level with AnyPhone Technology. The concept is very simple. We believe you should be able to add telephone features and applications to your business without purchasing any new equipment and while using your existing telephones,  any telephone.

The Ifbyphone automated telephone technologies work with any phone with a traditional phone number.  This includes home phones on POTS lines, business phones, VOIP phones and mobile phones.  With AnyPhone technology you have no hardware to buy to add new features and applications for interacting with your customers.

Today,  Ifbyphone AnyPhone Technologies support a wide range of inbound, outbound and API based telephone solutions. Over the coming months we will release new and innovative applications that push the limits of traditional call center and PBX solutions.  And they all work on any phone.

CLEC SIP Application Warehouse White Paper

We are very excited to announce the availability of our partnership program between the telephone carrier community and Ifbyphone. To better understand this initiative lets look together at the evolution of the world wide web and how SIP signaling is following a similar evolution.

When the first generally available web browser, Mosaic, was released by the University of Illinois, it supported the use of the HTTP protocol to access HTML formatted information. Before long millions of users where browsing the web everyday. But it wasn't until some very creative technologist realized that HTTP could be used to communicate server to server, that the web we know today developed.

The new Ifbyphone CLEC support provides the equivalent evolution of SIP. SIP was initially released as a telephone signaling protocol for voice communications. It has involved into a signaling and setup protocol for voice and video. The Ifbyphone carrier services take SIP to the next level, supporting SIP as a protocol for accessing the industry's first SIP application warehouse. With this new capability any CLEC or ILEC with SIP support in their softswitch can resell all of the Ifbyphone automated telephone applications. These applications range from a simple parallel find me similar to Google Voice, to complete Voice Broadcast and IVR solutions. Ifbyphone IVR solutions support text-to-speech, speech recognition, DTMF decoding, call recording, and recorded audio playback. All Ifbyphone applications are configured from a very easy to use customer portal with excellent reseller services.

Our white paper describes in more detail our view of the evolving cloud telephony space and its applicability to the CLEC/ILEC community.

Why Skype for Asterisk is more important than Skype for SIP

Back in September of 2008 and now today, Skype has announced initiatives to open the Skype network to SIP users. These two solutions; Skype for Asterisk and Skype for SIP are very different and offer significantly different capabilities.

Just to recap the details. Skype for Asterisk, which is still in closed beta, is a true Asterisk channel driver. This allows Asterisk based solutions to make, receive and transfer Skype calls. A significant capability of the SFA solution is its support for terminating a call to a Skype user name, for example a PC based user of the Skype client.

Skype for SIP is a very different animal. This service provides VOIP trunk support for existing SIP based PBX systems, which may include Asterisk. Unlike SFA where calls may be place to any Skype user, SFS calls may only be terminated to PSTN end points.

So what does this all mean to the Voice/Telco 2.0 marketplace. Overall Skype is beginning to leverage their extensive VOIP network to compete in the VOIP origination and termination marketplaces. Both of these services would enable a SIP based PBX user to utilize Skype as their transport vendor. For example, a traditional SIP PBX customers would directly use SFS for call termination and would provision Skype in numbers to provide origination.

From our perspective as a cloud telephony company, providing hosted telephone applications, SFA is much more interesting. While either service would allow us to provide IVR services to Skype users, the SFA Asterisk channel driver architecture allows us to terminate calls into call centers with no PSTN transport. Each call center Agent would just utilize a headset connected to a computer running the traditional Skype application. Customers calls would be able to originate from either a PSTN device or a Skype client, then route through the Ifbyphone IVR infrastructure and terminate to a call center via Skype's computer to computer transport. This has the potential to change the cost structure associated with supporting call centers. A Skype based call center would not require a PBX or for even any centralized telephony components. The call center agents could be virtually located anywhere in the world on high quality Internet connections.

Overall Skype's moves to open their network are exciting and create significant opportunities for innovative Cloud Telephony companies.

Why You Need 2 Telephone Companies

Historically telephone companies provided both dial tone and telephone features to business users. For example: when purchasing a telephone service for your business you would specify the number of lines and the features; such as voice mail, call forwarding, call waiting, three way calling, per line. Businesses with multiple lines would often terminate their phone lines into key or PBX systems that support line sharing across multiple extensions and supplement the available features. Your PBX might provide call center queuing, music on hold and enhanced voice mail.

Unfortunately, once you purchased a key or PBX system you were often limited in the new features you could add without purchasing a completely new system. For example, it is unlikely you could add Voice Broadcasting, Click-to-Call, or sophisticated Interactive Voice Response dialogs to your existing system. Even if these features where available you would need to hire a high priced consultant to configure them properly.

This has all changed with the introduction of My thoughts about the evolution of cloud computing and Cloud Telephony into the marketplace. Telephone applications in the Cloud are hosted applications capable of completing (terminating) a phone call to any telephone worldwide. Let’s break this down as bit.

Today, with the rapid decline in the cost of dial tone and the availability of VOIP communications services, companies may choose to purchase their out bound and in bound telephone services from separate vendors. For example a company could purchase traditional telephone services from the least expensive vendor in their area. When they pick up a telephone in their office, this vendor would provide the dial tone and place the call. This would be coupled with services from a company such as Ifbyphone for in bound calls. When a customer calls the business the Ifbyphone telephony cloud would route the call either directly to the business or to a hosted telephone application such as a virtual receptionist, interactive voice response dialog (IVR), store locator or virtual call center.

This hybrid approach provides companies with the least expensive out bound calling packages and the most flexible inbound call routing. In fact since the in bound calls are all handled via the Ifbyphone telco cloud, calls may be dynamically routed to your office phone, cell phone, and even home phone. This is important since if your office phone fails, because a bus ran into the telephone pole behind your building, with a couple of clicks you can reroute your Ifbyphone inbound phone numbers to a alternative location or cell phone.

In addition by using a Cloud Telephony solution for inbound calls, you are able to integrate your sales team that is using cell phones, with an outside call center and even home based users into a single virtual call center. Capabilities such as call queuing and call tracking are easily configured across users all of different telephone systems.

Are there advantages of using two telephone companies, one for out bound calls (dial tone) and another for in bound calls. Absolutely.

The Impact of Low Cost Telephone Transport

The integration of Jajah's network into the Yahoo Messenger platform signals a continuation of the movement of telephone transport from traditional PSTN networks to open VOIP transport. These new voice and data networks allow the user to bring their own device and access the world of telephony from new and exciting places.

Many of you may still remember when the telephone company provided all of your phones. The latest VOIP initiatives just continue the transition from telephone company owned devices to a device of your choice, by providing a device agnostic transport medium. Most telephone users now have access to open VOIP transport alternatives that are changing the pricing of transport. As transport costs continue to fall telephone users will obtain a new freedom in how that utilize telephone minutes. In a world of transport costs that are no longer a factor, users will want powerful applications that maximize the utility of these voice and data highways.

Let's break this down a bit with an example. Why have railroads failed in America and prospered in the rest of the world? The American highways were much too good, gas prices where too low, and the price of an automobile was a reasonable percentage of the typical Americans income. This lead to the creation of the largest automobile companies in the world. (These same companies are now failing because of a combination of historical mistakes and changes to the relationships between transport costs and personal income.)

The new VOIP networks are the highways of telephony. The traditional telephone companies are the railroads. Telephone Application Platforms such as Ifbyphone are the new automobile manufacturers. The Ifbyphone Telephone Application Platform delivers applications over low cost VOIP networks, affordable by any business, that leverage the power of low cost telephone communications in any business, at any location, any time of the day.

Why Does My VOIP Connection Sound So Bad?

Many new telephone services, such as Click to Call, Virtual Call Centers, Hosted IVR and Voice Broadcast, rely on voice over IP (VOIP) telephone connections to deliver services at the lowest possible cost. While some of these services sound great, others deliver voice quality no better than the walkie talkies your child recently received for Christmas. This blog entry will attempt to present, for a non technical audience, the basics behind VOIP communications that determine the quality of a phone call. Specifically this blog will address VOIP traffic transmitted over the public Internet.

Your voice starts out as an analog wave or vibration. Remember the telephone you built as a child with two cans and a string. The bottom of the first can vibrates, this vibrates the string, which then vibrates the bottom of the second can. In a traditional telephone these same vibrations are used to modulate an electrical signal transmitted over a wire which replaces the string.In VOIP communications your voice is converted from an analog wave into a series of data packets. These data packets, which share the Internet with email, web page transmissions and file transfers, are then transmitted from one computer to another where at the destination the data packets are converted back into a sound wave you can hear.

The process of digitizing sound is well understand and as in the case of DVDs can be very high quality. In fact many DVDs are better quality than traditional analog recordings.Unfortunately, unlike high quality DVDs, which have the capacity to transport a large amount of data, the Internet has limited bandwidth. Therefore when we digitize voice for transmission over the Internet we compress the data significantly more than the music on a typical DVD. This compression reduces the quality of the sound.

There are many standards for the compression of voice. However, in a typical engineering trade off; the more we compress the voice transmission, the more conversations we can transmit over the same Internet connection. The other side of this trade off is that the more we compress the voice the worse it sounds.

The vast majority of telephone calls today, even the calls made on your traditional home phone, are digitized. The traditional telephone companies use a compression standard called PCM or G.711. In fact VOIP telephone services that use G.711, such as Ifbyphone, sound just as good as traditional telephone calls.

Another common compression standard is G.729. Telephone calls compressed with G.729 are compressed on average four times more than G.711 or traditional telephone calls. This additional compression results in lower overall call quality.The telephone industry has a standard measurement of telephone call voice quality called the Mean Opinion Score or MOS. The generally accepted typical MOS (just Google MOS for more examples) for a number of compression standards follow:

Traditional PSTN phone calls: MOS is close to 4.5

G.711: 4.4 or better

G.729 about 4

G.723 about 3.5

G.726 between 3.5 and 4.3

Unfortunately this is not the whole picture. The quality of the connection of to the Internet used by your VOIP service provider also affects the quality of your telephone call. And finally some VOIP vendors use a Voice Activity Detection algorithm to reduce the bandwidth they need for your calls. VAD attempts to listen for silence between the callers in a telephone conversation and stop transmitting packages when no one is talking. If the VAD algorithm is inappropriately tuned the ends of your words will be clipped and overall voice quality will decline.

At Ifbyphone we are committed to the delivery of high quality voice services designed for business customers. We exclusively use G.711 for our business services. Since many of our services rely on automated voice recognition we need to set very high voice standards for the recognition to function properly.

Please feel free to post comments to this blog entry about your VOIP experiences and information you may have about the codex or compression standard used by your VOIP vendor.
