Hi MichiganTelephone. I read your blog when I was researching equipment, and it was very informative, and helped me decide to get the Obi.
I tried to resend the GV username and password in the portal, per your instructions, and it failed again. So, I did a factory reset, and used the wizard to redo my configurations, per Obi's instructions.
I did the factory reset by calling ***8, pressing 1 to confirm. Then, from the Obitalk page, I added the device. It re-registered the device, but kept my original device name and call providers, and showing both providers not registered/connected. I then configured using the wizard, and decided to start with Google Voice in SP2 first, since the wizard is designed for GV. It worked, first try, showing status "connected." Then, I used the wizard for Callcentric on SP1, and it worked, first try, showing status "registered." I tried test calls in and out with GV, and in with Callcentric (I haven't set up outbound calling with Callcentric yet). All worked! Big yaaaaay!
I think my problem stems from having gone back and forth from the wizard, to the expert configuration when I was first trying to set it up. I must have put in something incorrect, and it was never cleared out until I did the factory reset. I'm glad that I try the expert configuration though, because it did initially work for me to configure SP1, and gave me confidence that I can use it again in the future if needed (and understand this forum better).
Thank you both for your help.
