Subject: [VoiceOps] Calls to Verizion Failing
We have a client complaining that calls to the 818 area code are failing with a "No circuits available" message. The only common link we have found is the calls are terminating over our Verizon Wholesale trunk. We have other calls completing without issue across the rest of the country.
I don't know why Verizon would be generating an audible error message instead of sending us a SIP 503 error code so we could progress on to another carrier, which is what we have always seen them do in the past. Is anyone else seeing a similar behavior on Verizon?
