Can't configure Callcentric extension on OBi2182

[N7AS]

I have been having problems setting up Callcentric on SP2 of my OBi2182. Previously I had one of my GoogleVoice numbers on SP2, but I have been having no audio problems for a while. I have several extensions on my Callcentric account and want to route a Voxbeam DID to Callcentric via SIP URI. This works ok on my OBi200.
I have set-up my OBi2182 with the same settings, and Callcentric will not register. I am getting...
Connect Failed: 407 Proxy Authentication Required (server=204.11.192.160

In my credentials I have
Username: 1777*******102 that's Extension 102
Password: ***********

I manage all my configurations using the Local UI.

There must be some little thing that I am missing.

Any ideas?

I contacted CC. They suggested that I do a factory reset. Well, I didn't want to do that drastic move. What I did was to turn on auto-provisioning for the ObiTalk portal. I deleted SP2 through SP6 and started from scratch and put all 5 of my GV numbers back. This also cured the loss of 2-way audio on my GV numbers. I then disabled auto-provisioning on the ObiTalk portal. So all is well.

I am having a problem with just one of my GV numbers (Boston) but I guess I will ferret it out sometime.
