Thread: FXO outbound disconnect

  1. #1


    When I access an fxo port connected to my PBX and dial a pbx extension the connection works fine EXCEPT if the called extension has call forward to voicemail enabled. If it is enabled on the inter-tel pbx for the called extension at the point the call is rolled over to voice mail the 4X shows tha call as "disconnected" . Does anyone know a work around for this problem?

    It sounds like your central office might be interpreting the vmail tone as a disconnect signal (busy tone). The best method to procede would be to open a support request to have someone pursue this. Be sure to collect the system logs as they will be needed.
