AS5300 and ATA186 DSP Releasing Problems

Has anyone had DSP difficulty with ATA 186's sending voice calls out an AS5300. It seems like after awhile, the AS5300 is not releasing the DSPs. The codec is set to g723r63 under 2.14 on the ATA 186 and 12.2 (2) XB3 on the AS5300.

After all the DSP's are used up, the AS5300 doesn't take any more calls until a reload.

Show Call Resource Stat output:

DSP Statistics:

Utilization: 25 percent

Total channels: 96

Inuse channels: 24

Disabled channels: 0

Pending channels: 0

Free channels: 72

DS0 Statistics:

Utilization: 1 percent

Total channels: 96

Addressable channels: 92

Inuse channels: 0

Disabled channels: 0

Free channels: 92

Any help would be greatly appreciated

Re: AS5300 and ATA186 DSP Releasing Problems

This is a well know bug where the DSP's hang and are not available to the router anymore until a reload. The DSPmanager does not reload the DSP when the DSP timesout and this bug was fixed in later versions of IOS than you are running. Check bug ID CSCdu53333 for more information. If you go up to XB(5) or above or 12.2.6 mainline or aboe or 12.2.8T or above on the AS5300, this will fix your problem.
