PRI out-bound noise issues (Urgent)

Answered Question

CM 6.1.4

Our PRI Provider is AT&T

Guys,

All of a sudden today we started getting a loud (static noise) on out bound calls only

Sometimes the sound is more like a buzzing

We have 4 MGCP gateways on Cisco 2851 Routers

We have never had any problems like this and our equipment has been installed and running fine for years

We 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 know

I 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

I have this problem too.

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.
