    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.

    Something wrong with puting all logs in this webpage.

    My config is as follows:
    interface BRI2/0
    no ip address
    ip nbar protocol-discovery
    isdn switch-type basic-net3
    isdn overlap-receiving
    isdn protocol-emulate network
    isdn layer1-emulate network
    isdn incoming-voice voice
    isdn map address . plan isdn type national
    isdn static-tei 0
    isdn timeout-signaling
    isdn skipsend-idverify

    dial-peer voice 1 voip
    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.

    I have just discovered the same problem with almost exactly the same setup as you. I’m going to open a TAC case to figure this one out.

    Feel free to get in contact with me so we can work this together.

    Adam,

    I really want to cope with that strange problem. Unfortunately i have no CCO account on Cisco web page.
    If there is anything i can provide you with please give me a message.
    I suppose that there might be a kind of IOS bug. As you well know Cisco has got many caveats covering OVERLAP method.
    Anyway please give me a message if you know anything.

    Thanks a lot
    Mac.

    Ok, well Cisco are still not working on it but I have found something that seems to work although its not how it should work IMHO.

    If you add the ‘direct-inward-dial’ keyword to your dial-peer voice 10 pots it should work but of course then no dialtone.

    Let me know …

    Hi,

    Yes it is working now (no dialtone)
    Btw, i am wondering why i got double digits instead of other aftereffect.
    Anyway the problem is solved.

    Thanks a lot Adam.

    Well it seems it is a bug and of course I am sure you would like a dialtone 🙂

    The Cisco bug id (although you will not be able to view it without a CCO account) is CSCeg87727 so you will need an IOS upgrade eventually to have a fully working solution.

    Rgds,
    Adam

    Yes another bug is Cisco software, ughhh.
    If you will have any further response from Cisco staff regarding this issue, please post it here.

    Big Thanks anyway.
