I've just about had it with Vestalink. This AM, all of my incoming calls are going to their voicemail service (which is disableed in the GUI). Callers hear: "You cannot leave a message because the mailbox has not been set up".
Because I'm still using GV as a forward, all calls are intercepted by this message and no one can get a hold of me. For now, I've disabled the Vestalink forward in GV.
Further, on the Obitalk page, the device shows Unauthorized. I verified that all the settings were correct, still same. So I ran the auto configuration option. Now it says "Service not configured".
I've sent them an email, but this is pretty much the last straw. Between the excessive latency on GV forwarded calls, to the complete unreliability of "call has been rejected by the service provider" to now this latest "Unauthorized" error - I've about had it.
FWIW, my dad's box is also showing the same symptoms - so this is definitely on their end.
