Voice over Internet Protocol (VoIP) technology and software has been around since the 1990s. While mostly proprietary, many access and signaling protocols have been developed for VoIP. The development of the Session Initiation Protocol (SIP) standard has brought a level of standardization to VoIP. SIP can also support video, Instant Messaging (IM), and many other forms of media. Learning the value and operation of SIP is now important to anyone working in the field of communications and collaboration.
You frequently hear SIP discussed, products introduced, and services offered, but without much detail. What important information do you need to know about SIP before investigating SIP supported products and services? The most common applications are SIP trunking, followed by SIP phones. SIP can also be used for WebRTC session control, and there are other lesser known SIP implementations that support a range of devices and interfaces beyond SIP trunks and phones.
Understanding what SIP does and does not support helps you to grasp the implementation issues involved. Multiple elements in the SIP path must each be successfully interoperable with each other. However, when implementing SIP trunking, an enterprise can encounter a number of issues. The IP PBX and Session Border Controller (SBC) vendors and the SIP trunk providers can all contribute to the problems.
This paper will provide you with insight into:
- SIP and related protocols
- Session Border Controllers
- SIP trunk values, benefits, and economics
- SIP phones
- Interoperability with SIP trunks
- SIP trunk problems (IP PBX, SBC, trunk provider)and their resolution
- Bandwidth calculations for VoIP and SIP trunks
- Delivering a successful SIP implementation project
