I am a beginner of  ICE/STUN/TURN. I need to use ICE to help setup P2P connection for internet phones (voip) which can be behind NATs/Firewalls. 

I am studying tests/test-fullmode and example/simple-example. They all need to exchange candidates/credentials:

/home/libnice/examples$ ./simple-example 0 stunserver.org
Copy this line to remote client:

  Tyyp 33oInvKVEn1Lo6LkVVy6P5 1,2013266431,,47748,host

But in real internet telephony application, how can each side know candidates & credentials of the other side? Does PBX help both sides to exchange this information?
