[cisco-voip] ringback issues

[Ryan Ratliff]

Do you have 'voice rtp send-recv' applied on the router?  This is a global command and necessary for the router to cut audio through early, which you are trying to do.

PSTN calls are not getting ring back, sometimes it works. I have gone through cisco reading doc’s and all they say to put progress and tone ringbacks, but I still have intermittent issues
I have a H323 gateway with two CallManager clusters. The capture all dial peer goes to one and specific numbers to the other. I have no issues with calls going to the default VOIP Peer
Calls from one carrier (our provider) always get a ring back , but calls from others are a hit and miss.
What debugs can I run to tell me for sure it is a carrier issue and not me, or the other way around
 
My voip dial peer for example is
 
dial-peer voice 5076 voip
tone ringback alert-no-PI
destination-pattern 5076
progress_ind setup enable 3
session target ipv4:172.16.1.20
dtmf-relay h245-alphanumeric
codec g711ulaw
The CallManager server has the flag set for progress as false
