    NetVanta 3430 phone registration issues

    d3hunt New Member

      Greetings everyone,

       

      I have NetVanta 3430 router connected to T1 and few IP phones connecting to asterisk PBX in the cloud behind it.

      I'm switching to new PBX and the issue I encountered is that with new PBX I can register one phone and it will work fine, but if I add second phone it registers and within few minutes becomes unreachable.

      I ruled out issue with PBX by registering phones from different location.

       

      Attached is config with some settings removed for security.
