SIP and media Toolkits

amsip SDK
amsip packageamsip is a SIP toolkit with a simple and flexible API. This products can be used to implement SIP Audio & Video User-Agent.
Using amsip, Developpers can concentrate on building your application and features: amsip will be in charge, internally and transparently, of media negotiation, audio and video device management as well as codec and RTP media.

osip2 and eXosip2 SDK
amsip packageosip2 -and its higher layer eXosip2- is one of the oldest SIP stack. The project was founded in 2000 and has been improved and maintained up to now. It's today one of the most stable, portable and interoperable stack you can find.
eXosip2 API is very flexible and will help you to benefit from the SIP capabilities.

antisip-mediastreamer2 SDK
amsip packagemediastreamer2 has been written by Simon Morlat and is a audio & video media framework providing tools designed for VoIP. When antisip was founded, we acquired some rights to integrate the product in antisip's portfolio and we pushed a lot of effort to improve its stability, flexibility and portability. This version is now a fork of the original project since 2010.
antisip-mediastreamer2 is a graph based SDK composed of filters connected together. It's very scalable, reliable and portable. Using plugins, you can extend it to support whatever codecs you want or acheive any operations on data in general. (resizing, conversion, video mixing are -already implemented- examples!)
