Hi
i have CUCM 10.5 and a voice gateway 2921 connected to PSTN over BRI and then SIP trunk link this :
CUCM ====> voice gateway (SRST)=BRI==>getway PSTN=====SIP========PSTN
calls over CUCM are good (in /out)
calls en srst mode (in =ok) (out ==nok) we get as message (Cause i = 0x829F - Normal, unspecified)
we contacted the PSTN and he said that there is mismatch codec
plaease find in the atached files the debug and config gateway and capture of the codec that we used actually send from PSTN:

Can you explain further? The call is going out the PSTN via BRI? or SIP? I don't see any SIP config (dial peers, etc.).

This is a SIP capture. Which device is terminating the SIP call? Is the carrier's gateway doing SIP and handing off BRI to you?

Hi
my srst gateway to PSTN gateway over BRI and this pstn gateway connected to swisscom by sip connection
srst==BRI===> pstn gateway ====SIP==> PSTN
pstn said the the codec must be PCMA so what config should i do to resolve this pb
regards

Do you control the SIP gateway? If so, post the config. This is where the change will need to be made.

for info: the calls over cucm are good
