This pull request is in conflict. Please resolve conflicts. Note that sofia-sip has been moved out of tree so you would first want to make a pull request to that library to add the support you need.

@gslab-opensource hi, I have a different approach and make bfcp work by make a fake channel and join a conference, no bridge support so far. but I like your code seems more complete to support bridged calls. I'd like to test and help to get you code merged. so I suggest we break the pr into smaller ones so it would be easy. Steps would be:

• make a pr to https://github.com/freeswitch/sofia-sip (done)
• make a standalone module like https://github.com/freeswitch/mod_janus
• make a pr here with only core code
• the libbfcp can be hosted at the original place or copy into mod_bfcp if you want to.

I found a pr already exists. freeswitch/sofia-sip#36

@gslab-opensource ping. Let me know when we can start working on this. I already splited mod_bfcp and the build process is all passed. However I haven't got time to try.

@mjerris Would you please let us know what more is required for this to proceed further, besides resolving merge conflicts.
