We have a call flow of CUCM 7.1 IP phone --- GK controlled ICT --- GK -- matched default tech prefix ---- voice gateway --- QSIG trunk --- PBX --- destination phone .
Calls complete but with no ringback before called party picks up. Debug q931 on the voice gateway with the QSIG trunks shows the call set up with progress indicator indicating ring back is sent be we don't hear it. Any ideas appreciated!
