Repeat calls"rejected by service provider ... reason 480", Obi 100, simonics, GV
rhk1:
I'm using an Obi 100 to a Google Voice account, using the simonics GVGW gateway since some time in December,2017. (I had been using the Obi 100 with my Google Voice account with no problems, or, at least no unresolved problems. The setup including the GVGW had been working fine up until a few days ago (or, at least that's when I noticed the problem--the window of time in which the problem might have started might have been as long as two weeks as I don't make phone calls very often).
The problem now may have two symptoms:
* The first thing I noticed was that I could make a call to a given number, but if I later had to call that same number for whatever reason, the second attempt did not work, and I got a voice message saying (approximately) "rejected by service provider ... reason 480"
* Then yesterday, I tried to make a call that, iirc, to a number I hadn't called previously and I got the same message.
Since then I've googled a fair amount, and didn't find anything helpful.
Aside: Obviously, I want to solve my problem, but, in addition, I find the whole thing of using Obi and now the simonics gateway and google voice using a POTelephone pretty confusing, and would like to understand more, including these specific questions:
* Where is that message generated--in my Obi 100, at simonics, at obi, at google, or somewhere else?
* Which is the service provider who rejected the message--is it simonics, obi, google, or something else?
* What is the definition of reason 480? Is there a list of such messages, what they mean, where they are generated and such? Are those messages unique--I mean if I get a message 480, does it always mean the same thing, or might the meaning vary depending on what device or service provider generates the message? (See next paragraph.)
Today, I found DSL reports, and, in an old post that might or might not be relevant, I found a reference to reason 480 and it seems that it means (at least sometimes) "No route to host". So now I have similar questions--or just let's say, what does it mean, no route to host--what specific device(, server, or host) doesn't have a route to what other specific server or device?
Aside: BTW the post that mentioned reason 480 is: http://www.dslreports.com/forum/r28918051-Can-t-register-2nd-ATA-phone-line-with-FPL?search=reason%20480
Continuing: I have trouble believing I have any connectivity issues at my end, but let me describe "my end".
I have a DSL modem, in bridge mode connected to a Ubiquiti edge router (that was added to my setup to allow me to setup some QOS "stuff" to make the Obi work better--that has been in service since something like September, 2017 with no unresolved problems), the Ubiquiti has Etherlink links to Ethernet switches at my desk and my son's desk. At my desk, I have two PCs connected, the Obi100, and sometimes I plug in either a laptop or a WAP to use a tablet. The permanently connected devices use static IP addresses, and I have no recent or current problems with connectivity (to the Internet) for any of those devices.
Sorry for writing so much.
Obviously, I want to get the current problem resolved, so that is my highest priority. But, like I say, I would like some better understandings re the questions I've listed.
Thanks for any help you can offer!

That voice message is generated in your OBi when it receives the 480 error code.
List of codes: https://en.wikipedia.org/wiki/List_of_SIP_response_codes
The only calls which use OBihai servers are calls over the Obitalk network (ie calls to a 9 digit OBi number like that on the bottom of your OB100). GV calls (through Simonics gateway or not) do not use any OBi equipment except your OBi100.

Thank you very much, drgeoff!
For anyone also viewing this thread, this does not resolve my problem, but it certainly helps--an update of my thinking:
1. This rules out the Obi servers as the source of the message (and as the source of the problem).
2. See below--reason 480 could be a problem on the callee's end (i.e., neither (my) Simon Telephonics nor (my) Google Voice account) but, because it has happened for 3 different callees, at three different business or government facilities, I still suspect my end more than the callee end. (I guess from my Obi 100's perspective, the callee could include my Simon Telephonics or Google Voice "accounts".)
3. The other thing that I can hope for (although I prefer not to depend on luck), message 480 says that the callee is temporarily unavailable which implies that the problem is temporary, and maybe the problem won't recur when I retry the calls tomorrow. ;-) (I've made a few calls today just for test and haven't had the problem--I guess I should try the numbers that had the problem, even though no one will answer today.)
I'll also read that Wikipedia list of messages a little more carefully, I may get some insight (in the way of ruling out problems) based on the messages that I'm not getting.
Further information / insights will be appreciated!
From the list of messages on Wikipedia, reason 480 is:
<quote>
480 Temporarily Unavailable
Callee currently unavailable.[1]:§21.4.18
</quote>

Just a further update--if my hope is that the problem is temporary, it is not temporary enough--still having the problem today.

Things to do and things to consider.
To do:
Go to simonics.com/gw and use the button that reads Offline/Online to toggle your account offline and then toggle it back online. If it's already listed as Offline, then maybe your device isn't registered. Check on that.
To consider:
Google Voice via XMPP does not provide us any useful information about why a call doesn't go through. It either rings or we get a generic failure message back from Google that is translated by the SIP gateway into 480 Temporarily Unavailable, lacking any better info. It could be busy, disconnected, rejected because of insufficient funding, or other things. This is unfortunate but it's out of our hands.
Also, Google Voice is kind of flaky, and for some people more than others. Why? We don't know because Google doesn't talk about it. A number of people have experienced problems in the last week where their incoming calls (either to Obihai GV connection or to Google Voice Gateway) have no media and thus get rolled over into voicemail. This isn't the first time and there have been other strange issues.
Neither Obihai (correct me if I'm wrong, but I havent seen it) nor Simon Telephonics will provide any guarantees about Google Voice service for these reasons. But when it works, it's pretty nice. :)
As a general status update, I am not seeing any widespread issues with GVGW nor with the several accounts I have configured there for testing/regular use. But if you think there's a problem with the service or your account on the service please let me know directly.
