    Busy out channels in Dual PRI

    garabedy New Member

      Would someone be able to provide guidance on busying out channels on a PRI to test that calls are flowing to the second PRI? I followed the example on SIP to Dual PRI and am able to receive and place calls just not sure how to test the calls going to the second PRI if the first is full.

          Garabedy,

           

          You could add an overflow route to your second sip trunk in your call controller to test, you could MMB the first trunk in the call controller and then test in the adtran by showing isdn resources to see b-channels in use.

              Could you explain this in more detail, I have the same issue with 3 PRI's on a NetVanta 640. Only I am the SIP provider through my Soft switch.

                Patrick,

                 

                 

                Thank you for your response. Do you know, If I used the sample explained in the  “ Total Access 9XXe - SIP to dual PRIs sample configuration” document, as far as the Adtran is concerned it  should overflow to the second PRI, it just a matter of testing on the call controller?

                    Garabedy,

                     

                    In the adtran unit using firmware R10.9.6

                     

                    Isdn-group 1

                    Connect pri 1

                    Connect pri 2

                     

                     

                    Pri 1 will overflow to 2.

                     

                    How is the pbx set to route calls?

                    How is the call controller set for call limit on sip trunk?

                    How is call route set on that trunk group?

                            1. On T01 I have max-number-calls 46 (since I am using 2 PRIs with 23 b channels a piece)

                            2. On ISDN-Group 1 I also have max-channels 46

                            3. on the PRI interfaces - role network b-channel restarts disabled

                            If you'd like to test your overflow, shutdown the first pri link by issuing a shutdown command on interface PRI 1. You can then place a call and use TA908e# show isdn resource to see your call connect or alert on the 2nd pri.

                            If the call does not come in on the 2nd pri with the first one shut down, verify you have operational status of your pri interface

                             

                            TA908e# show interface Pri 2

                             

                            you should make sure your PBX and your adtran unit are agreeing on framing, coding, and isdn switch type.

                             

                            framing and coding are handled on the T1 interface, and isdn switch-type commands are handled on the PRI interface.

                             

                            on my T1s I use ESF framing, and b8zs coding, and the isdn switch-type is NI2. Yours may be different, but as long as they match you should be fine. Also, I would remove the lbo setting until you test your switch type, framing, and coding.

                             

                            Make sure when you're finished to issue the no shutdown command back on your PRI 1 interface.

                             

                            Hope that helps,
