DSP module test

Found in the net:
test voice driver and select 0 (for DSP slot in my case), 2 (DSP) then 16 (Display DSP Keepalive Status)
Result as below
DSP Keepalive Status Display:
=============================
DSP 1 is Alive, State: 4, Keepalive Sent: 130, Skip 131
DSP 2 is Alive, State: 4, Keepalive Sent: 97325, Skip 97329
DSP 3 is Alive, State: 4, Keepalive Sent: 97326, Skip 97328
DSP 4 Not Exist


Another DSP issue and error 0x80AA

I had to solve another problem with switching congestion equipement.
Again
Cause i = 0x80AA - Switching equipment congestion
However dspware version from “show voice dsp detail” was OK I tried:
test dsp device 0 all reset but it hasn’t changed my status. Resetting router aka reload and no change at all.
What I found was here:
router# Show voice dsp group all
DSP groups on slot 0:
dsp 1:
State: FAIL, firmware: 23.8.0
Max signal/voice channel: 16/16
Max credits: 240

dsp 2:

Another time another DSP module to replace.

DSP issue and switching equipment congestion

A few weeks ago I faced an issue with DSP module. I was looking for a solution but there was a poor description in the network. Even Cisco error decoder hadn’t help at all. I hope this will help someone.
The problem waswith calls establishing. Phones were calling but no voice channel was created. In logs just short info.
Cause i = 0x80AA - Switching equipment congestion
I checked translation-rules, dial-peers etc. but when no changes have been done it wouldn’t be so simple. Some more discoveries and diagnostic as below:

Warning! DSPs1, in slot 0 are using non-default firmware from flash:
This is not recommended, the default version is 23.8.0

Difference between DSP NUM 1 and 2 shows that number 1 was broken. Fast change corrected and issue and all came back to normal work.
