ICS7750 with MRP which has a T1 card. It's been runnig for a long time. today we had the following issue: when receive inbound call from outside the quality is good,and internal call between ip phones are good, but call from ip phone to outside, the called party will hear very serious static. Show controller t1 1/0 only shows a lillte error in the very first interval which should not cause this kind of serious static issue. I think maybe something to do with the carrier or the dsp module, the top couple channels have the issue when make outbound calls, but lower channel are ok when calls incoming.
Any idea? Thanks

This sounds like a hardware or telco issue. Do you have more than one PRI that you can swap with this one to eliminate hardware?

I have the same feeling it's telco issue. It recovered today.
