    *Cause No. 18 – no user responding.*
    This cause is used when a called party does not respond to a call
    establishment message with either an alerting or connect indication
    within the prescribed period of time allocated.

    What it means:
    The equipment on the other end does not answer the call. Usually this is
    a misconfiguration on the equipment being called.

  • Thanks for reply,

    But I’m able to call those number from my cell phone and othere pri.

    I’m only having this issue on 2 pri line rest are working ?

  • Ist the same operator connected to the pri-line? Perhaps another
    telco-operator can not connect to the desired destination – for whatever
    reason.
