ATT Voice Call Routing Issues

[John Stitt <jstitt () hop-electric com>]

Anyone on the ATT voice side of things able to reach out off list?

We’re seeing inbound call issues from AT&T and firstnet phone numbers across multiple providers. Outbound calls have no 
issue. 

So far we’ve had no success with normal channels of support. 

The calls are dropping after five seconds, but they do initially make it through and you can have a few seconds of 
audio if you answer quick enough. If you don’t answer, you’re get a recorded message that says your call could not be 
completed as dialed and then gives an error code of “message six US01LV”

Thanks
