Although this topic has deviated (a lot) from the original post that talks about "...has not received a response from service provider..", it is still valid and still a problem. Please lets keep this on topic for those receiving this message. If you do not hear this message then this thread does not relate to your problem.
First no reset nor changing the device has helped . When I first tried those solutions, I thought it helped at first then the problem came back
Now I mention "Toxic Numbers" these are numbers that I can see in my mother's call logs when she mis-dials a number that causes the problem to start. recently she dialed this one (it is not a valid number in use so no harm done in posting it) +1 503 503 3811 . Previously I posted another similar number, also unassigned) , +1 360 238 5631 that when I dial any one of these or other identified numbers it causes the obi 200 to start giving me the "...has not received a response from service provider.." message on that and subsequent calls, even to valid numbers. I have confirmed this happens with multiple numbers which explains why it is such a problem for my mother who is elderly and frequently mis-dials numbers. Then she gets stuck at the recording exacerbating the problem and mis-dialing more numbers. Usually the device will reset itself
My other post was here
http://www.obitalk.com/forum/index.php?topic=18882.0I suspect something in Obi or GV is not properly handling the disconnection with some numbers that are not in use, and thus not allowing a connection to the next dialed number. Since Google allows multiple simultaneous calls, I do not believe it to be Google more likely because of the single call limitation in the Obi, that is where the problem lies. SOmeties however the Obi goes into this mode seemingly on its own, but I suppose this too could be related to a call not properly disconnecting, even an incoming call.
It seems to me that if someone were able to monitor these calls from the server end it would be easy to identify where the problem lies but then again GV is a free service and nobody really seems to care.
Possible solution, is it possible to force the obi to re register at the end of each call? This is at lease worth investigating and might be the reason the problem clears itself, because a re-register.
ATTN NAYSAYERS: please refrain from eluding to this being a problem related to MY configuration or MY obi or something like that. It has been tested and confirmed on MULTIPLE Obi 200s all have been reset at one time or another and tried again only to return to the same problem.
