XML-error on cisco 78XX phone-very irritating :(n :(

[Ajith Nayak]

Hello Friends,

We have cisco 7840 and 7821 models we frequently get XML error issue.

Is there any bug?? with only this particular model?

Or in ? CUCM 9.1.2?

We have cisco call manager 9.1.2

We are on latest firmware

We have extension mobility configured

When we get this issue we ask users to unplug the cable and plug it back that fixes the problem but we need a permanent solution for this.

And when we  get this XML error we also cant open corporate directory even login logout don't work 

Please help !!!!

Hi Ajith,

I did not find any specific bugs for such behavior. Can you capture the console logs from one such phone when the issue is reported before unplugging and replugging the phone. The corresponding extension mobility traces from cucm will also provide details of what the issue could be.

Dear Manish,

Good morning..!!

We have already opened TAC case a month ago but still no proper fix... if you have access to TAC tcketing tool propbabley i can share the TAC case number we have all logs case troubleshooting everything there...

This issue will happen suddenly on any random phone. 2 to 3 times in a week in any of the office location.

Hi Ajith,

My suggestion would be to get the TAC case reopened if the issue is not resolved yet. The existing engineer can involve his escalation team if he is unable to diagnose the problem with the logs that he has collected.
