I have two OBi devices on my network. They've worked pretty well throughout the past 2+ years but today, mid-day, they both quit working.
On the OBi1062, when trying to place outgoing calls, I get a busy signal tone and the error displayed on the screen says "Call Failed: 403 Forbidden".
On the OBi100, it says "the number you dialed xxx-xxx-xxxx was rejected by the service provider. reason is 403"
When I login to
obitalk.com, my OBi Dashboard shows both OBi devices status as green/connected.
When calling either phone, the OBi phones ring but when I answer them, I can't hear anything on the OBi phones. The phones calling the OBi phones continue dialing and go straight to voicemails after they ring x times.
Any ideas what could be going on or where I could test/troubleshoot to figure out what's happening?
