Architecture folks architecture.
Have some ideas no code....

Communications of this type has two aspects (a) control and (b) data 
just like FTP.

Have the control work with TCP. and the data work on UDP.
What I mean with control is a TCP registration with a server, just like 
a chat session. You get your 'ip-phone' to be part of a voice extension 
based network like a pabx. The server knows you exists when you log onto 
the server.

If you have multiple users, then you can call someone. Just type in the
extension number. The server will know who is who (ext->ip translation)
and initiate a call.

The thing is what platform shall we agree on Indy9 or Indy10.
Delphi or C++...
