First of all I'm sorry for posting this twice. I forgot to subscribe to the mailing list. I'm running SipXecs 4.2.1. Everything works fine, I have some ATAs hooked up and running. However I bought some Nortel 1535 sets and I can't get them to register. After attempting to register for a moment they display a "420 Extension not supported" error. The IP phones register fine with my ITSPs and with Asterisk, somehow they seem to work with everything except SipXecs and SipXecs seems to work with everything except those phones. I've tried changing every setting on the phones and SipXecs and so far no luck. Googling for "420 extension not supported" yields no useful information. The phones are manually configured as they have firmware 2.5 and I can't find 1.92 anywhere. _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users/
