Proposed Next-Gen Networks' VoIP Support has Limits

Proposed next-generation networks, superb as they may be in so many ways, still do have boundaries in their ability to support VoIP over their data-centric IP networks.

Even though data use is increasing, and data traffic is beginning to crush the carriers’ networks, voice will persist to be the killer app. This signifies that what everybody's going to want are systems that allow high-quality voice experiences.

Recent numbers we've seen floating past the office window here say that voice revenues will still represent almost 70 % of overall mobile revenues by 2014. So it's an concern that needs attention.

In a present interview TMC's (News–Alert) CEO Rich Tehrani did with Payam Maveddat (News-Alert),vice president, product management, Mavenir Systems, Tehrani said, "We hear more and more about high-definition voice features in IP communications products and services. What is going to force wideband audio and HD VoIP into the mainstream market? How long will it take?"

Maaveddat replied that from the wireless angle, "wideband codecs will become prominent primarily in order to get the voice quality to a advanced level as mobile devices become more widely use for all voice applications such as audio conferencing. The challenge stays in radio access as how fast the carriers will incorporate these codecs in the core of their network and whether this transition is economical or not. It will occur much sooner in the fixed VoIP application. It will be at least 3 to 5 more years."

And industry observer Stacey Higginbotham also recently wrote that "Voice over Internet Protocol penetration among U.S. businesses will increase rapidly over the subsequent years, reaching 79 percent by 2013, compared to 42 percent at the cease of 2009, according to research out today from analyst firmIn-Stat ( News-Alert). At this point I surprise what market demographic represents the last stand for legacy circuit switched voice. Will it be consumer landlines or will it be mobile voice over 3G networks?"
It's an open end question. Higginbotham notes that ‘current telephone networks are steadily being phased out as the world moves to IP communications. At present in the U.S. only 78 % of consumer homes have a landline and only 22 percent rely on them exclusively.’

VIPR: New Developments in the VoIP Market

This is a latest development in the VoIP market. This is how one of my colleagues, Cullen Jennings gave details to me.

At present we have two widely deployed global identifiers for reaching people. First is delegated address out of DNS and the other is phone numbers. So I believe an address like email: carol@johnson.com or xmpp:john@gmail.com to roughly be out of the DNS namespace and phone number to be out of the E.164 name space.

Phone numbers have lots of parts that are not cool, but they also have some cool parts: they are widely understood with social conventions of giving out someone else's phone number to a third part, they are easy to enter on devices with highly contained user interfaces, humans can almost keep in mind, they are easy for a human to give to another human. The major problem with phone numbers is, well, the only thing you can do with them is make a phone call. Say I desire to have a Skype video call with you, or view your twitter feed, or send you an email and all I knew was the phone number. In most of cases it would be nice to use a phone number to reach some internet service for user. Fundamental, this vipr technology resolves the problem of securely mapping a phone number to URL.

Obviously there have been other attempts at mapping phone numbers to internet resources. Public ENUM is one best example. However, most of the prior ones have failed because the economic incentives to make the technology deploy did not line up right. The vipr technology creates sure that every player that has to do something to make the technology deploy has an economic incentive to go do whatever they need to do. It greatly relies on peer to peer technologies.

VoIP Gaining Ground, So Where Will Legacy Voice Make Its Last Stand?

Voice over Internet Protocol penetration among U.S. businesses will rise rapidly over the next few years, reaching 79 percent by 2013, compared to 42 percent at the end of 2009, according to research out today from analyst firm In-Stat. At this point I wonder what market demographic symbolizes the last stand for legacy circuit switched voice. Will it be consumer landlines or will it be mobile voice over 3G networks?Current telephone networks are slowly being phased out as the world moves to IP communications. At present in the U.S. only 78 percent of consumer homes have a landline and only 22 percent rely on them exclusively. In the next three years I dream both numbers will be much lower, which is why the FCC is looking at how to hold Broadband access (which is necessary for IP telephony) for all.

In the mobile world, legacy voice will connect around for a while longer. Even though the next-generation Long Term Evolution networks will support voice, it’s still unclear how carriers will control voice calls over the all-IP LTE network. In addition, the existing 3G and even 2G networks will still be around delivering voice calls, so legacy voice is still going to rule on mobile phones.
