I’m hoping someone might be able to shed some light on the following issue.
I’m trying to get a Cisco 7906 to register with Asterisk. I’m sure that I’ve configured the phone correctly and the auth user and password values are definately correct, but Asterisk constantly returns a SIP/2.0 401 Unauthorized error. I’ve followed suggestions on forums to set NAT=never and qualify=no for the extension; this worked one time, but now doesn’t seem to make any difference.
I’d appreciate any help or advice anyone can offer.
I am a newbie, but I just configured 6 Cisco 7960 phones. Start with:
Are you running the phone’s original firmware? The phones do not support SIP out of the box, you need a different firmware.
You have to set the password the phone uses to login to match the “secret” setting you gave it in asterisk. You can telnet to the phone or use the phone console, but there are going to be a lot more settings, so the best way is to use tftp. Run tftp on a server, go to the phone, press setting, 9 to unlock, the default password is “cisco”, and change the tftp server address.
#2 has a lot more steps, that was just a general procedure list.
You have to register the phone lines to asterisk and the phone params have to match asterisk, again you can use the phone itself or a tftp server. If you need it I can post the config files you will want the phone to download.
I, like yourself, have several Cisco 7940 and 7960 phones setup with SIP firmware, which work perfectly. My issue lies with the Cisco 7906 which is really being a pain. I’m sure that I have the configuration files right, so I assume that it must be Asterisk that is at fault as it is returning the aforementioned 401 error.
