    PRI Delay

    jlanning New Member

      First let me thanks for any help I can get here.  I have a 908e and am very new with the Adtran brand.  What I am trying to accomplish is receiving a SIP connection from my carrier and then pass off a PRI to my Asterisk server (going to be a shortel system eventually).  I have things working kind of but I get a 2 second or so delay when dialing in, and all audio is delayed for 2 seconds at least.


      Here is my config. any help would be greatly appreciated.

          Try adding the following two commands to the PRI interface:


          interface pri 1

            isdn name-delivery setup

            calling-party name-facility-timeout 1

          This kind of delay on a PRI connection is often due to the Adtran device waiting on CNAM from the PBX that is never sent. The above should greatly reduce or eliminate it.

              My device doesn't have the calling-party name-facility-timeout command in it.  Here is the Adtran version I am running.

              After having issues with getting a license error after upgrading the firmware so I called support.  They found that the Adtran was trying to send calls from one SIP trunk to another SIP trunk and that was causing the delay.  to do this we had to add a permit and deny to each trunk group.


              Thanks for your help.
