7961G keeps registering repeatedly

[palominoandrew]

Two 7961G phones on the same switch keep registering repeatedly on their own. I didn't find any strange settings with the switch but then again I am fairly new to Cisco.

Any help is appreciated!

Thanks,

Andy

Are you using CME or CM ?

[palominoandrew]

CME 4.0

Thanks,

Andy

[paolo bevilacqua]

Can you check the phones are getting an address from the router and there isn't a rogue dhcp server around.

[palominoandrew]

No rogue dhcp going on anywhere on the network. Any other thoughts?

Thanks,

Andy

Send show interface for the ports involved.

I hope this is what you mean...

Also, they are both 7931 models, not 7961. Sorry.

[paolo bevilacqua]

Allright go ahead and upgrade firmware. I haven't checked what the latest is.

Hi,

If you havent tried, please perform a factory reset.

that has helped in one of our phones doing similar things.
