    One PRI to two servers

    kb9mfd New Member

      I have a application that I have one pri that two sip PBX's need to access. How to I define that incoming numbers go to what sip server and have both sip servers access the PRI. I have one server working, but the other not yet. Here is the config so far, PBX (T02) works, but PBX2 (T03) does not, and I am not sure how to define what numbers to go to PBX2 (T03). Both PBX's are the same make/model. Thanks! - Jeremy
