We are trying to turn up a new PRi circuit and I am having issues getting it to stay connected. According to ATT everything is set correctly on their end.
I have the following when I run a “pri show span 1” I get the following.
Primary D-channel: 24
Status: Up, Active
Switchtype: National ISDN
Type: CPE
Remote type: Network
Overlap Dial: 0

and when I run “pri set debug on span 1” I get the following over and over.

I have a ticket open with Sangoma but haven’t heard back yet and was hoping someone could shed some light on this issue.
I appreciate any help.
