VoIP bookmarks from Klaus Darilion
Below you will find descriptions and links to SIP and RTP stacks, applications, test utilities, SIP proxies, SIP PBXs and STUN server and clients. Most of them are open source :-), but not all of them :-(
If you have any comments please feel free to contact me: --> klaus.darilion at pernau.at <--
There are also other VoIP related portals and link collections.
Note: I mainly searched for C/C++ stacks and applications. There also exist a lot of stacks and applications for other programming languages, especially for java. If you are looking for Java stacks/applications, please ask Google (search for: NIST java jain).
