IP Phones reregister periodically

[Dmitriy Chindyaskin]

Hi, please help.

Cisco CallManager 6.1.3.3190-1.

Phones lose registration periodically with the server for 1-2 minutes, but only models 7965,7970,7975. Phones to other models 7940, 7941 such problems do not have. All machines are on the same LAN and connected to the same switch without PoE. All phones have a power supply.

I have not found nothing in Bug toolkit.

How we can help?

What firmware are you using on the phones?

Justin

Hello Dmitriy,

Can you confirm me or provide me the following informamtion:

Go to RTMT afther that go to the system logs and find one that says device transient connection look for the one with one of the mac address of the phones and post the complete alert as a reply to this.

Also can you confirm us your firmware version:

Is this happening on a remote site?

Can you send me a show interfaces of the port that connects either the phone and the CUCM.

Can you also provide us the show run of those ports?

Regards,
