    Intermittent Call Rejection    UNASSIGNED_NUMBER

    timlytle New Member

      I have an Total Access 908e (3rd Gen) with a SIP trunk in and a 2 ISDN PRIs out to  a subscribers Phone system,     intermittently (like every 3rd or 4th call) on outbound calls from the Customers PBX calls are rejected by the TA,    when that happens I see the call attempt in the ISDN Debug, looks like the TA is disconnecting the call with a cause code of (UNASSIGNED_NUMBER)  however it never send an INVITE out the SIP trunk to my switch, My assumption is that the customers PBX is sending something invalid on theses calls but I can tell what from the debug  

       

      Any help is appreciated!

       

      Thanks
