VoIP/SIP open-source project list resiprocate:

Http://www.sipfoundry.org/reSIProcate/

Resiprocate is a high performance, object-oriented, C ++ SIP stack that is compliant with RFC 3261. it includes des support for a wide variety of operating systems, including Windows and Linux. it has full support for UDP, TCP, and TLS transports on both IPv4 andIPv6. It also implements the full set of specifications for DNS usage in SIP, including naptr and SRV lookups (rfcs: 3263,291 5, 2782) using an asynchronous DNS Library (Ares ).

The resiprocate project consists of a stack and a small collection of applications. the resiprocate stack is currently used in two specified cial products and is quite stable. resiprocate is ideally suited to individuals or companies that are implementing one of the following sip applications:

-Phones (eg, embedded );

-Softphones (any platform );

-Gateway;

-Proxies;

-B2buas, or;

-Im/presence servers or clients.

The winrtp (winrtp) was developed as part of the Cisco IP softphone product. cisco IP softphone is a PC based telephone integrated with avvid, and works with the Cisco Call Manager. the primary focus of the winrtp is to ensure that it works well with other products in avvid including desktop IP phones, gateways, etc. it can also be used as an independent component .; it is written in C ++; it is a COM component. (not an ActiveX control ). this makes it easy to use using any programming language like C/C ++/Java (using J/direct) etc.
