Opal is a full-featured voip library that supports a variety of protocols and
multi-media fornats. Features include:
* Low latency RTP stack designed specifically for real-time multimedia
* Full featured H.323, SIP and IAX2 protocol stacks
* Audio codecs including G.711, GSM06.10, Speex and iLBC.
* Video codecs including H.261 and H.263
* Run-time loadable codec interface for proprietary or codecs such as G.729,
H.263, H.264 and MPEG4
* Completely Open Source using the commercially friendly MPL 1.1 license
Through the use of a platform isolation library called PTLIB, Opal can run on
tiny embedded systems or multi-processor servers.
BTW: OPAL is an acronym for Open Phone Abstraction Library, but that is not
really important :)
