HI i'm running Callmanager B.E. 8.6 version, i have a PBX's IVR conected trough a Cisco ATA 187. In can call the pbx ivr extension but i can not select any options; IVR ignores dtmf.
This is the call flow:
PSTN T1 CAS>>>H.323 GATEWAY>>CALLMANAGER>>UNITY CONNECTION CALL HANDLER>>ATA 187 (REGISTERED OVER THE WAN))>>>PBX'S IVR.
Tahnk you.
