If you have a TDM network you should be able to call your SS7 provider and ask them to do a trace on it so you can see where it's dropping. Then you can call and put in a trouble ticket with the carrier. I always have the customer stay on the phone so you can do a 3 way call with the carrier. That way they don't have to talk about things they don't know and you can get to the correct people.

I have a customer saying that they are getting reports from their customers that they're getting "number is no longer in service" errors when calling them.
I checked Metaswitch SAS for a number that experienced this issue and we don't see any inbound attempts from that number. The call would have come in via a traditional TDM connection to a tandem.
I reached out to the Primary contacts in NPAC for the originating caller (Comcast). They told me to bugger off and to have the end user call support. Did I make the wrong move?
