Double digits with OVERLAP

    Hello,

    I have v. strange problem with Cisco 1760 (IOS ver 12.3(7)XR).
    The problem is connected with the look of called phone number comming
    from PBX to Cisco (BRI interfaces).
    Every dialed digit is doubled (in case of using OVERLAP dialing).
    For instance if i dial 506047553 (on PBX side) i get 550066004477555533
    which is then sent further through IP.
    The situation is quite opposite if i use ENBLOCK (by pushing redirect
    button).
    Deriving from the logs below I am almost sure that PBX is sending the
    digits properly thereby the problem is located somewhere in Cisco
    configuration.

    A part of my config is as following,


    interface BRI2/0
    no ip address
    ip nbar protocol-discovery
    isdn switch-type basic-net3
    isdn overlap-receiving
    isdn protocol-emulate network

    isdn incoming-voice voice
    isdn map address . plan isdn type national
    isdn static-tei 0

    destination-pattern .T
    session target ras
    dtmf-relay h245-signal h245-alphanumeric
    codec g729br8
    !
    dial-peer voice 10 pots
    permission orig
    huntstop
    destination-pattern 99999
    port 2/0


    There is no translation rule set.


    I've spent many hours struggling with this case, unfortunately without
    any success.
    Does anyone have any ideas what might be the problem?

    Thank You,
    Mac.
