T1 PRI + Reject Frames = Dropped Calls

Hi all,

I’m having an issue with my Asterisk setup, we’re running a T1 PRI with 24 channels on a single span TE110P Wildcard. I’m using the latest Asterisk as well as Zaptel, including libpri.

The problem I’m seeing is calls seem to drop when some console error messages come across such as:

My configuration in zaptel.conf is:

   span=1,1,0,esf,b8zs
   bchan=1-23
   dchan=24 

Inside my zapata.conf:

   switchtype=national
   context=vicidial
   signalling=pri_cpe
   group=2
   channel => 1-23 

I’ve done some searching online and most people attribute these messages to incorrect timing set on the span, I really have no clue what else to do, could anyone help?

Thanks

Run the command “pri debug span 1” from the Asterisk CLI. It will show any hangups(DISCONNECT) and why.
