Dear mlombardi

APC is connected via H323 TRUNK

this is not endpoint and should'nt use DSP till voice path is established - in this scenario with SIP trunk (IP direct is enabled)
For dialing and signalling should use only signallin channel not DSP - there is no audio yet, no dial tone and busy should be send back in signalling channel.

I agree that phone is different story and i have made test when phone calls in the same way - first use DSP (ofcourse for dial tone) but when call is established DSP was released. Phone H323 avaya type 9670 and the same SIP trunk.
