Products: 4GSIP
4GSIP
is an implementation of RFC 3261 compliant SIP protocol on top of AMPS
library. The stack provides a set of functions for parsing and generation
of various SIP methods and messages, including the session description
protocol (SDP). The stack is being enhanced at the time of this writing
and new methods and message types are being added.
The stack also provides a complete implementation of RFC 3261 based SIP
transaction state machines. The transport layer (as mentioned in RFC 3261)
functionality is mainly hidden inside AMPS library.
The stack has been designed such that it can be enhanced to IP Multimedia
Subsystem (IMS) compliant functionality in a short time. In fact Advanced
IMS plans to do it in near future.
4GSIP is available under GPL open source license for its open source
usage. A commercial license is also available for closed source commercial
usage. Comprehensive support is available for both open source and commercial
licenses that includes several support model options.
