Cisco 3905 phones rebooting automatically

[Mohammed Asif C Y]

Hi,

I have CUCM 8.6 and combination of 7900 and 3900 phones in my VOIP network, recently i have started facing issue with 3905 phones, they are resetting automatically and says Registering.

I just wanted to know what logs i need to collect from RTMT to identify the reason for this issue.

Thanks

Check you network as these issues are generally caused by loss of connectivity.

Hi,

The phones reboots up for 50-60 per Day.

If I take a look in the CUCM the phone ist registered,

But the issue is facing only the 3905 phones. All other phones working fine.

Do you have an idea how I can troubleshoot These issue ?

From RTMT can you see the reason code of the phones there are rebooting?

Or you can connect via CLI:

Event Viewer-Application Log

    File get activelog syslog/CiscoSyslog*.*

    File get activelog syslog/AlternateSyslog*.*

Event Viewer-System Log

    File get activelog syslog/messages

And access the IP Phone messages status to see whats happens:

Hi Lenardo,

How do we check the reason code using RTMT? i think we can get the route cause if we get reason code.

I have the same issue, only with the 3905 phones. The phones register fine but after 2 minutes tries to re register and they fail, so the phones resets and then register again.
I can call or receive calls fine while the phone is registered.

Any advice?
