    Adtran 908 PRI Routing

    pitviper0717 New Member

      We have a customer set up with 2 SIP backhauled PRI's.

       

      Customer is dialing (slowly) and their PBX inter-digit timer expires. Upon expiry, the customer PBX sends a PRI SETUP with an invalid number. The Adtran 908 receives the PRI SETUP and sends the SIP INVITE to the soft-switch. The soft-switch rejects the call with a SIP 484 (Address Incomplete) back to the Adtran 908. Which is what we expect to happen.

       

      Once the Adtran 908 receives the SIP 484, it tries to route the call down the 2nd PRI back into the customer's PBX.

       

      1) What could be causing this behavior?

      2) How can it be corrected?

       

      Configuration is below. IP addresses and passwords have been changed to protect the innocent...
