I have a cisco IP PHONE 7941G-GE already with SIP firmware, but when i upload the config file with asterisk extension, etc the phone keeps saying “Registering” and never finish registering.

There are any log that i cant use to see if asterisk is blocking the phone or something like that ?

Can anyone help me out ?
