Thanks for the help, it sounds like that is the answer. I went online and read up on what SIP is and how it is used. Now that I know a little it becomes obvious that the OneSuite support doesn't know much, so I gave up on trying to install it on my 1032 Sp2 and put in another GV number.
On SP1 I have had Anveo for a few years and removed it a week ago. This evening I installed CallCentric on SP1 and got the same result as with OneSuite "Register Failed: 403 Incorrect Authentication". CallContric had sent me Emails with the proper numbers to use so I know I got it all right.
Also I can't receive calls on GV on SP2. It gives one quick ring and quits, then I get a voice mail by Email from the Anveo that I removed at least a week ago.
I'm hoping for another answer.
