[Savannah-hackers] savannah.gnu.org: submission of The GNU SIP library

[moizard]

A package was submitted to savannah.gnu.org.
This mail was sent to address@hidden, address@hidden

If it already is an official GNU package, it will be approved shortly.
Otherwise it must be discussed on address@hidden for approval. 

Aymeric MOIZARD <address@hidden> described the package as follows:
License: lgpl
Other License: 
Package: The GNU SIP library
System name: gsip

The LGPL gsip library provides an implementation of SIP described by RFC2543 
(www.ietf.org). SIP is the Session Initatiation Protocol. It is used to 
initiate, modify and teminate mutimedia sessions. SIP handles registration 
services and negociation of media. It is a telephony standard for VoIP which 
aims to replace H323 and instant messaging applications. The SIP library can be 
used in embedded systems (cellular) as well as for implementing proxy, gateway, 
registration and conference servers. Port currently exist on GNU/Linux(2.2), 
solaris (2.5) and VxWorks (RT OS).

SIP facilitates implementations of services for next generation telephony 
networks. A LGPL SIP library should accelerate developpement of low cost 
telephony and migation to a mail-model for \"billing\" phone calls. (billing = 
0$...) 

The SIP stack (the gsip library) is still under heavy developpement. It already 
provides minimal parser code, complete multithreaded transaction handling in 
conformance to RFC2543 (through finite state machine). The applcation layer 
controls the transaction with events and is aware of modification through a set 
of callbacks. At this step, only a transactionnal API is provided. A higher API 
(like connect()/disconnect()) should be provided in next developpement. The 
stack currently use UDP (TCP is in next step) SDP used by SIP (rfc2723) is also 
nearly finished. The stack is yet usable to developp IP phone on it.
