I am able to place a call from a SIP phone to an OOH323 Trunk. The phone rings but when the callee answers the call still continues to ring at the caller’s end before eventually disconnecting with “No one available to answer at this time”.

See attached H323 log, the real IPs have been substituted. I have installed Digium G729 codecs on the server.

My OOH323.conf:

[general]

h323id=ObjSysAsterisk
