I am trying to get a 7912 Cisco IP working with an internal SIP server. Was able to upgrade the firmware which I done successfully.
I config all the parameters via the phone web portal. However, when the config try to register with the sip server, I got unauthorized.
U 209.150.20.xxx:5060 -> 10.x.x.x:5060
