Hello Peter,
sofia is a library for handling SIP signaling. It can help you to
establish calls, negotiate codecs, etc. What it does not help you with
is the media part of calls (sending, recieving, mixing audio and video
streams).
You can take a look for example here:
http://wiki.opensource.nokia.com/projects/SofiaTutorial
It might help you with your first steps, but be sure that to make
call(video conference) you will have to jump through lot of hoops.

Regards
Martin

Hello Peter,
you will have to try much harder when asking questions here. It would
take a crystal ball to guess where the problem might be. There are lot
of people out there willing to help, but you must give us better chance.
If you want any assistance, include following details:

- Your setup (i.e. who is client, who is server, what are their addresses)
- Debug outputs and sofia messages (check this
http://wiki.freeswitch.org/wiki/Sofia#Debugging_Sofia-SIP)
- Relevant pieces of code (single call to function is not enough)
- What you have already tried

Without these, no one will bother trying.

Also, please always include mailing list address in To or Cc.

Regards
Martin
