I have an Obi200 with Google Voice as SP1. It was set up about four months ago for testing with a GV-assigned number. I recently decided to start actively using it, and ported over my longtime ATT landline number (with an interim port to T-Mobile prepaid).
Today I went to the ObiTalk interface to add CallCentric Pay-As-You-Go as SP2 for 911. But when I clicked configure SP2, I got some sort of brief error message along the lines that it was unable to configure now, try later or contact support. Waiting didn't help. Then I noticed that there was a delete-configuration symbol next to SP2 (as well as next to SP3 and SP4). So I clicked delete-configuration (and confirmed that I wanted to delete), which also caused "not configured" text to appear to the left. Then I was able to configure SP2 as CC with no problem.
While it was an easy fix, any ideas on why I might have had to do that? I nosed through the forums and didn't see any reference to any such issue. BTW, even though I don't need SP3 or SP4 right now, I went through the motions of choosing to configure those as well, with the same error and same resolution. Also, I am doing the configuration remotely, rather than from the same WAN ip the Obi is connected to. That couldn't cause such an issue, could it?
