[cisco-voip] ringback issues

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
