SIP-UA missing

[LyRa]

Hi all!

We have Cisco 881 routers at the branch offices and only on one of them we've got that problem when sip-ua suddenly disappears:

Reboot solves the problem.
All configuration across routers is the same.
How can i troubleshoot this problem?

Hello,

Can you check if you use the same IOS as with the rest of the routers?

Yep, it's 15.4(3)M7.

Hi,

On registrar configuration, add a refresh ratio timer.

Eg.

registrar ipv4:195.211.120.9:9060 expires 900 refresh-ratio 50

Thanks, i'll try that.

Unfortunately, today sip-ua gone missing again :(

Maybe i can retrieve some logs about sip-ua somewhere?

[Maren Mahoney]

What is the output of show sip-ua statistics? You many need to clear the statistics so you can show new errors.

I'm also thinking that debug ccsip errors or debug ccsip non-call might show what's happening with the sip-ua.
