Yate is production-ready software and is easily extensible with licensed under the GPL with an exception for linking with OpenH323 and PWlib (licensed under MPL).

PJSIP
PJSIP also features extensions, such as:

PJMEDIA is a complementary library for PJSIP to build a complete, full-featured SIP user agent applications such as softphones/hardphones, gateways, or B2BUA.

PJLIB-UTIL is an auxiliary library providing supports for PJMEDIA and PJSIP. Some of the functions/components in this library: small footprint XML parsing, STUN client library, asynchronous/caching DNS resolver, hashing/encryption functions, etc.

PJLIB
A small footprint, high performance, ultra portable abstraction library and framework, used by PJSIP and PJMEDIA.

PJLIB is about the only library that PJLIB-UTIL, PJMEDIA, and PJSIP should depend, as it provides complete abstraction not only to Operating System dependent features, but it is also designed to abstract LIBC and provides some useful data structures too.

VOCAL
The Vovida Open Communication Application Library (VOCAL) is an open source project targeted at facilitating the adoption of VoIP in the marketplace. VOCAL provides the development community with software and tools needed to build new and exciting VoIP features, applications and services. The software in VOCAL includes a SIP based Redirect Server, Feature Server, Provisioning Server, Policy Server and Marshal Proxy along with protocol translators from SIP to H.323 and SIP to MGCP. Our hope is that these modules will act as building blocks to help you create better, faster and stronger VoIP systems.
