It was found that SIP-based basic interoperability works, and works well. SIP is a relative youngster compared with the ITU's H.323 specification for voice-over-IP call control, and to achieve this level of interoperability so quickly via SIP is impressive. But there's work to be done on the more advanced functions, and it's apparent that some conformance issues remain to be solved. Still, users can expect rapid development on SIP-based advanced functions as the business cases for implementing SIP become more pervasive.

VoIP (Voice over IP) is a new technology that enables telephone communication over packet switched networks such as the Internet using the Internet Protocol (IP). Internet Service Providers (ISPs), Application Service Providers (ASPs), Local Exchange Carriers (LECs), and Inter Exchange Carriers (IXCs) may all desire or need to implement this technology in order to gain or retain a competitive edge by offering an array of new services to their subscriber base. When VoIP is implemented on a Linux platform, it is supported by a rich operating system that is under continuous development and debugging by talented programmers and developers who willingly share their solutions with the rest of the community.
