What does the above message means . CCO says it is a DSP Timeout error . We have two E1 working on a 3660 router . The error comes in only one of them. Cisco's suggestion is to talk to cisco technical support

Phone Calls at randam does not gets thru.

this is a bug with DSP possibly, could also be hardware. Are you on newer IOS, 12.2.6a fixed this bug but I suggest running latest 12.2 or 12.3 code as more DSP bugs have been fixed since this one.

If you have NM-HDV, use the 'test dsprm slot#' command where slot# is where HDV is and choose option 1. Need to have 'term mon' on first to see output. This will ping each DSP and tell you if it is alive or not.
