B-channel oos and protocol error 510

abakarsintal · ‎10-22-2012

Dear all,

I have some some issue couple of days ago. The telephony system of my client worked well and suddenly the cannot make external calls via E1. I checked the config and for me it seems to be ok. When I checked the SDL file, I can see the B channel out of service error message following by the

"MGCP PROTOCOL ERROR: <S1/SU1/DS1-0/29@ATD-CCM-GW.xx.xxxx.xxx> CRCX error code: 510". They have A CUCM 6.0 and Cisco 2821 as gateway with 12.4 (25f) advance IP service IOS.

I perform the following actions without success:

-From the CUCM in the advance service I forced the Bchannel to bring it in service,

- no mgcp/mgcp, -reboot the CUCM and the Gateway,

-reset the controller throug CUCM,... in vain.

They contacted telco and has confirm that everything seems to be ok. Find below the information that can help you to undestand better
