The Power of SIP

This week the ANPI marketing and sales team is attending and exhibiting at IT Expo in Las Vegas. It is one of the two shows that we will use to launch our retail offering of Hosted Unified Communications (UC). Over the next four days there will be opportunities for us to speak, learn and discuss the latest in IP communications. As such, I do regret accepting a slot to discuss SIP Trunking, since I no longer believe it is the latest thing in IP Communications. SIP Trunks are expected to overtake T1s as the most sold form of broadband for businesses in 2015. Additionally, the cost of a SIP Trunk has fallen from an average price of $12.50 per CCS (Concurrent Call Session) to $10.00 per CCS. Finally, if vendors implement the SIPConnect 1.1 standard, as many have committed to do. Then the issues associated with interoperability testing will be reduced or potentially eliminated. SIP Trunks are becoming commoditized.  And that is not a bad thing. It just means it’s not as exciting to discuss as it once was.

SIP (Session Initiation Protocol) on the other hand has a long ways to go before its capabilities are fully realized. SIP is similar to HTTP. It is limited to simple negotiation of data streams between endpoints. It is be to negotiate real-time a voice connection, or exchange text messages, presence information, or other kinds of data including video moving between IP endpoints. SIP is an enabler of UC functionalities and applications. SIP also plays a central role in the IP Multimedia Subsystem, protocols which define the architecture of next-generation mobile networks for streaming text, voice and video to mobile subscribers.

There is an ongoing dialogue of the future of SIP versus WebRTC. SIP will continue to be used in network and carrier-based applications for some time to come. WebRTC or Web Real Time Communications is an open source platform and suite of APIs to develop a common interface that is browser based to support communications between any and all end-user devices such as computers, TVs, phones, tablets, etc. WebRTC is meant to “democratize and decentralize tools” for content creation and communication.

The future is not a debate as to which of the protocols will survive but how each will be applied. As an industry we are fortunate to have both contributing to the success of IP communications.
