Unable to register few extensions

Hi,

I am able to register about 7 - 8 extensions except two. Configuration is same for all extensions.

1010/1010 (Unspecified) D N A 0 UNKNOWN

I am using asterisk 11.7 and Cisco 7960 phones with firmware 8-12

What happens when you try to register your extensions?

Bad Pattern Match?

Duplicate Extension Warning?

Config not loading period?

Nothing…I have enabled max verbose but doesn’t show anything on CLI

Also I am able to call out from those extensions but not able to call them.
On the phones they have valid IP address.

Resolved…The issue was it was with phone setting, registering with proxy was disabled

Thank you for quick reply
