Registering an Adtran 706/712 IP phone with Asterisk
The Adtran 712 was a little puzzling when I went to register it with Asterisk. Once you set up the “ProxyServer.Address.1 (xxx.xxx.xxx.xxx)” and “RegServer.Address.1 (xxx.xxx.xxx.xxx)” on the SIP settings page and the “Reg.AuthUserID () ” and “Reg.AuthPassword()” you would be done on most phones. But the Adtran would not register and was not even indicating it was trying on Asterisk using SIP debug. Popping over to the phone summary page it did not indicate any line was configured.
So the trick turns out to be heading over to the buttons configuration page and set a button up with “Button.Type (Line)” and “Button.Realm (PBX)”. There may be other variants of these but these options worked for me. Once you have done this and reset the phone, the phone should register itself to Asterisk.
I haven’t done a whole lot of testing with the phone yet but it seems like a good phone, maybe on par with a Sipura or a Polycom. The phone itself does not have any power inputs other than the PoE so an injector is needed if you don’t have a PoE switch. It has an RJ-style jack for a headset. There is also a button for the headset pickup next to the speakerphone button. Unfortunately the flat black finish of the phone shows finger and face oils. The backlit display is nice and reminiscent of a Polycom set.
