I have calls failing inbound from Level3 to my Chicago SBCs?related? Area code 215 Opening with them now. Sean Salvadalena | Network Engineer From: VoiceOps [mailto:voiceops-bounces at voiceops.org] On Behalf Of Tim Donahue Sent: Monday, May 18, 2015 10:07 AM To: voiceops at voiceops.org Subject: [VoiceOps] Calls to Verizion Failing Hi all, 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? Tim Donahue

I stand corrected. Verizon didn't say NTF, they said they resolved it but were not specific on how.
