VoIP goes Mobile

April 11, 2013

VoIP mobile phoneMobile VoIP phones are phones that allow VoIP calls by connecting directly to an IP network using technologies such as Wi-Fi or Ethernet. Two types of protocols are generally supported: cordless/DECT/PCS for short range or campus communications where all base stations are linked into the same LAN, and 3G/4G for wider area communications.

There are several methodologies that allow a mobile phone to be integrated into a VoIP network. One implementation turns the device into a standard SIP client, which then uses a data network to send and receive SIP messaging, and to send and receive RTP for the voice path. Another implementation uses a soft-switch like gateway to bridge SIP and RTP into the mobile network’s SS7 infrastructure. In this implementation, the mobile handset continues to operate as it always has (as a GSM or CDMA based device), but now it can be controlled by a SIP application server which can now provide advanced SIP-based services to it.

As the technology improves it becomes more and more evident that mobile VoIP is more than just a passing trend, it’s the future of data transmissions. It is estimated that the surge of VoIP applications will cost wireless phone companies all around the globe a combined $479 billion USD in losses through 2020. Or put in another way, at least 1 billion customers will save that combined amount of money by 2017. These figures are calculated from both national and international calling revenues, as well as text messaging revenue, all of which can be used via VoIP and messaging applications at low cost or even for free.

It’s easy to see how the mobile operator industry business model conflicts with the expectations of Internet users who are accustomed to having free access anywhere they visit, or call. That’s why most innovations in mobile VoIP is expected to come from campus or from projects like Asterisk, which in spite of being Open Source, is perfectly capable of powering IP PBX systems, VoIP gateways, conference servers and virtually any other communications app you can think of, which makes it very attractive to small and large businesses alike, and is a reality today in many call centers, carriers and even governments’ offices worldwide. Other sources where VoIP research is taking place are those corporate areas where the potential benefits are high enough to produce incentives to carry on expensive R&D, such as in medical or military applications.
