PRI out-bound noise issues (Urgent)

Post by Guest » Tue Dec 28, 2010 6:30 am

CM 6.1.4Our PRI Provider is AT&T Guys, All of a sudden today we started getting a loud static noise on out bound calls onlySometimes the sound is more like a buzzingWe have 4 MGCP gateways on Cisco 2851 RoutersWe have never had any problems like this and our equipment has been installed and running fine for yearsWe have done no recent work or updates on our equipment I suspect AT&T they tend to do have equipment failures and not let us knowI have not restarted any GW’s yet. I will have to wait until tonight Any one heard of this type of issue before? Thanks, Tom

On t he gateway check "show controllers t1"(or e1 as case may be)and "show interface" look for CRC errors, slips, carrier transitions, and other errors.
