I just started getting this same error on the OBI 200. I have a wifi dongle in it.
I have placed calls on hold before pressing the flash button when receiving a new incoming call, but this time I was on a long hold, and so pressed flash, got a dial tone, and attempted to make a new call with the first on hold.
That is when I got the no service configured error. Did this cause this?
Am I supposed to be able to make a new call with one on hold?
Following the solution, I logged into my dashboard and don't see any yellow triangle. Navigating one step deeper, still don't see it. Only a green active dot.
I only have one line.
Am I supposed to go into a secondary menu to see this?
UPDATE - just before I posted this, tried making a call again, and it's working without me doing anything. What was going on that this got solved? Still would like to know where to find the triangle in case the issue repeats.
Thanks.
Bob
