Thanks @azrobert,
The ring pattern is set by X_DefaultRing in the SPx Service.
I don't know why I didn't notice that parameter. I was looking for something like "Ring Pattern"
You can use any Ring Profile you want. All SPx Services on my OBi110 and OBi200 have a default of Ring Profile A. Did you use a wizard to setup Callcentric? Maybe the Ring Profile was changed during setup.
I used the ObiTalk portal provider wizard to setup both Google Voice and CallCentric and that's how it defaulted the profiles. Ok, I changed my SP's to X_RingProfile=A and X_CodecProfile=A, (SP1 was set to A/A but SP2 was set to B/B).
Some tones are included in the Ring Profile. The Tone Profile is set in the Phone Port under Physical Interfaces.
Thanks, I didn't realize that the Tone Profile was assigned under Physical Interfaces. I had assumed it was set with the Ring Profile under Voice Services.
Thanks again
