[cisco-voip] DSP timeout.... TAC says echo cancel

64 is the default. 128ms requires a daughter card for your VWIC2's.

Subject: [cisco-voip] DSP timeout.... TAC says echo cancel

so I have a DSP timeout issue I've been working on and off, on for months.

Lead TAC engineer says I should change my echo cancellation to 128 (which should be the default)  My only options in CM (being it is a MGCP VGW) are 24, 32, 48, and 64.

if I look at the voice port I have other options 80, 96, 112, 128.  How do I fix it so that I can do 128 per the TAC engineers request to fix my DSP timeout issue:

4/11/2011 8:48 AM : DSMP-3-DSP_TIMEOUT  1244: Apr 11 15:48:51.382: %DSMP-3-DSP_TIMEOUT: DSP timeout on DSP 0/1:1: event 0xDC, DSMP timed out, while waiting for statistics from the DSP. DSMP State = S_DSMP_COLLECTING_STATS

TIA

Scott
