Re: CME High CPU with 3911 SIP Phone

Hi Evandro - Tough to say without show run or any information. Please make sure that IP CEF and IP routing is enabled in show run. Check as well for any tracebacks. During high CPU, please collect debug ccsip messages or debug ccsip all. We have to be careful when enabling the debugs so we do not cause the router to hung.

Please log the debugs in the router buffer. Disable logging monitor and logging console. Make sure that the router buffer size is set to 10000000. That should be able to tell you what kind of SIP messages migt be causing such high CPU
