7960 and DSP errors

Good morning.

I have a 7960 phone in a remote building that is experiencing DSP errors. The user says her phone will "crackle" and she is dropping calls.

When I have looked at her phone, I don't see the errors and haven't actually seen a call get dropped.

When I look at the phone's webpage, on the debug display I have the "DSP Error [0xffffdfd1, 0xffffdfd1, 0xffffdfd1, 0xffffdfd1](3) -8239 - (0)" repeated many times. I also have "29: DSP Keepalive Timeout [0xffffffff, 0x14, 0x0, 0x2](3) 19 - (0) (43)" entries in the log.

I have reset the phone, and also upgraded the software to the 8.0(4.) version that was released in August. The phone is still having problems.

I checked the switchport that the phone is plugged into and it has no errors.

There are 15 other phones in the same building and none of them show any DSP errors.

I am correct in thinking this is a hardware issue with the phone? Or does anyone have suggestions where to look for more details?

Thanks!

Steve

Re: 7960 and DSP errors

This DSP error messages has 2 cause:

1- There are some bugs with this error:

CSCdw76866: DSP Keepalive Timeout displayed on the phone

This bug been fixed in load P00303020200 or P00303010400 or later. If you are running a

higher load most likely that is not the cause.

CSCee82974: DSP Keepalive Timeout when phone is rebooting

This is a duplicate of

CSCee05802: 7960 struck with Booting Dsp alarm on its display

This bug is fixed in 03.3(03)ES56 and 03.3(04)ES18

2- Every other cases that we have seen with this error was caused by hardware failure (DSP crash on the phone) and have to replace the phone.

Thanks.

It's running the latest load, and it's not happening on any other phone in the building.

Just my luck, that phone is not under warranty...
