Termination code for discontinued phone numbers

[lmora]

Hello all


I've noticed that my termination call provider is sending a specific message for calls dialed to discontinued phone numbers and those calls are automatically dispositioned as NAs in ViciDial.

As I use to redial all NAs because they include genuine non answers I also end up redialing those discontinued phone numbers, so I'm wondering if there is a way for ViciDial to label/disposition discontinued calls exclusively.

This is the sample of the last part of the sip messages sent from my provider.

I have no idea about this too.

Im also trying to find out why disconnected numbers are being disposed as NAs

Well, About 30% of the time what your carrier sends you in the US is wrong. PRI hangup cause codes and SIP codes are not standardized from carrier to carrier so we default to NA.

We have analyzed millions of calls through a dozen different providers to come to this conclusion, and sadly you will often get the same response from a carrier for network congestion as you would for a disconnected number, just because one of the carriers in the path of the call was sending an improper termination code.
