No audio on T1 calls

I am having an issue with a T1 line. I see the calls coming into the system, but I don’t hear any audio. I set it to put a person on hold forver (just to play moh) and its not working either. In the logs I see the calls, but no audio
Any suggestions?

Is the PBX local to the phones?

what hardware does the T1 terminate on?

Digium t1 Card, Ill get the exact model shortly.
The pbx is local, but I even tested sending to an IVR and I dont hear any audio

from Asterisk

pri set debug on span 1

lots of stuff there, so watch the log file as a call is handled , all “ins” should have a corresponding “out”

You should see the PRI conversation, if the call is well negotiated, chan_dahdi then answering the call and bridging it with another endpoint, be that MOH (local) or any other endpoint.

They are Digium - WCTE23X
The strange thing is that when I do service Dahdi Status, it is showing up as unkown even though I have it configured in the module.
It used to show a PRI now nothing.
I have it configured as:
Framing: ESF/B8ZS
Signalling PRI-CPE
Nation ISDN2
Context From-trunk

Stop asterisk, then try stopping and starting dahdi and look at the status

service asterisk stop (fwconsole stop)

service dahdi stop
service dahdi start
service dahdi status

I am getting the below. As a quick experiment I tried switched it to FXS and then the status shows that instead of unknown
Thank you

Is your T1 really carrying a PRI or is it just a good old 24 channel RBS? Because a PRI can’t do FXS and if a RBS then likely you should be using e&m

Its a verizon PRI. I had just toggled to FXS to just see if any changes I am making are actually being reflected in the status.
Thank you

For PRI’s to work on top of dahdi you need libpri compiled and working.

Kind of hard to do message by message, perhaps

https://wiki.freepbx.org/pages/viewpage.action?pageId=1048598

and choose your flavor and do the libpri/dahdi bit. . .

Is there a way for me to test to see if it currently is compiled? I have asterisk 13 installed (new install) should I try 16?

If its dahdi/libpri properly compiled against your running kernel then it will automatically load and

pri set debug

will spring into life.

When I run pri set debug on span 1, it does say that it is starting debuging

And when a call is initiated?

What about

service dahdi status

At this stage if there is paid support, I would use it as the system has been down for a while already.

Thank you
