7961G keeps registering repeatedly

Unanswered Question
Sep 12th, 2009

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

I have this problem too.

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

Hi,

If you havent tried, please perform a factory reset.

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