I have this problem, A PBX user places a call to an Cisco IP phone, and does not hear a ringback tone before the call is answered. The cisco call manger is 6.0 version and the H.323 gateway is the 3545 pri gateway. What can I do ?. A Cisco IP phone user place a call to PBX user, and tone ringback is heard.
This could be attributed to the fact that the gateway was unable to determine the progress-indicator in the call setup and consequently could not cut-through the audio befor the call was answered.
You could try a couple of commands on the gateway:-
Initially configure the 'voice call send-alert' in global.
If this does not appear to working the configure the following commands on the incoming call-leg dial-peer. These generally hidden commands.
progress_ind setup enable 3
progress_ind alert enable 8
progress_ind progress enable 8
Hi MK thanks for your help.
i have this scenario:
a PBX Alcatel with a link E1 QSIG to Cico Router 2620, and the Gateway is registered as H323 gateway at CCM 6. And i already configured "progress ind setup 3" under dial-peer voip. So is there a parameter tha i must to change at the CCM?.
