Cisco CME, High CPU Utilization

Hello.

There is Cisco router 2851 with CME 7.1 on it with PVDM2-48 (the result of show version and show inventory is attached).

There is SIP trunk connected to this router. Also this router serves for 50 SIP phones Linksys SPA922/Cisco SPA504G. The transcoder is configured on the router for detecting dtmf signals from rtp flow (only for inbound calls; provider sends inbound dtmf signals in inband g711). Outbount calls are not processed by transcoder.

Some times (a few times a day) I see the following warning:

*Aug 13 14:56:53.479: %IVR-3-LOW_CPU_RESOURCE: IVR: System experiencing high cpu utilization (97/100).
Aug 13 17:59:22 192.168.90.2 4830:      Call (callID=26073) is rejected.

Also debugs and partial config are attached.

I don't understand what is a cause of my problem.

Thank you.

P. S. Sorry for my english

Try 15.0(1)M3 that is very stable.

Thank you for answer.

But I have no enough hardware resources to store this IOS on my router:

FLASH: 64 MB

RAM: 256 MB

No, that is fine.

Re: Cisco CME, High CPU Utilization

Thank you for answer.

Sorry, but can you give it to me (if you able to go to cisco support), I have no access to cisco software resources.

Sorry once more if my question was not correct.
