[cisco-voip] [External] Re: Help with Test Calls

[JASON BURWELL]

I just called from a Verizon mobile in the Charlotte NC metro area and get the auto attendant. Works fine.

I have seen these types of problems before where the routing table the carriers use to send traffic between each other is “broken” somewhere. I don’t know enough about carrier transport to say exactly but that’s how it’s been explained to me in the past.

We did call trap with Centurylink, our tandem provider, and problem calls are not reaching them. They recommended having the callers open tickets with their local providers.  This hasn’t resulted in any success with getting a carrier to address this issue. This started on Thursday, 2/20/2020, and we have been unable to reproduce it with our local phones and have been relying on other callers to open the tickets.
