=== THIS PROJECT HAS BEEN DEPRECATED === Please consider using the reConServer project instead - it is far more powerful and includes a B2BUA module: https://github.com/resiprocate/reConServer Introduction ============ This is a reSIProcate-based B2BUA library. The library is libb2bua.so It is built on top of reSIProcate's dialog usage manager (DUM) It was distributed with reSIProcate releases up to and including the reSIProcate 1.8.x release series. It is known to work with those releases but may not work with releases beyond 1.8.x Building ======== TODO: a configure.ac script needs to be created for this project. It can probably be created by copying the configure.ac script from reSIProcate itself and removing many things that don't relate to this B2BUA project. Background and technical notes ============================== The code has been adapted from a previous project. Consequently, the initial import to the reSIProcate repository doesn't fully adhere to reSIProcate coding standards. Nonetheless, it is working code, so a decision was taken to commit the code as-is, without modification, and then gradually overhaul it in subsequent commits. Some key points about this code: - It produces a shared object - to produce an executable, the B2BUA class must be instantiated and put to work. Such an example exists in the apps/basicB2BUA directory. A typical implementation of a B2BUA must implement the following classes: - b2bua::CallRoute - b2bua::CallHandle - b2bua::AuthorizationManager - b2bua::B2BUA - It relies on rtpproxy from http://www.rtpproxy.org to relay the media streams. There are also various patches for rtpproxy 0.2: - rtpproxy sends notification to the B2BUA on media timeout - fix a file descriptor bug - timeout on either direction The rtpproxy patches have been posted on the rtpproxy mailing list: http://lists.rtpproxy.org/pipermail/users/2008-May/000016.html Daniel Pocock http://danielpocock.com email@example.com /* ==================================================================== * * Copyright 2012 Daniel Pocock.
