Callmanager Routing Issues

    I have a Cisco CallManager in a mixed environment with a Nortel PBX. I
    am starting to take individual extensions(for test purposes) and rout
    them to the CallManager. This way when I start to roll it out company
    wide people do not have to change their phone numbers. Here is my
    problem. When I put my old extension on my IP phone this is what
    happens.

     I can call out to IP Phones, PBX phones and the outside world
     The outside world cannot call me
     PBX phones cannot call me
     IP phones on my network can call me.

    I have looked and I am unable to find the problem. My PBX person
    assures me it has been routed properly to the CallManager. I am sort
    of new but if the extension has been associated to my IP phone it
    should work, I think,

    Any thoughts.

    I would check if PBX is sending all digits needed for call routing on IP
    telephone network for a start...

    What kind of gateway are you using? If it's IOS based, try the
    command:

    csim start <phone_no>

    That should ring your phone. If it doesn't, then your gateway is not
    configured correctly. If it does, then you need to find out what the
    PBX is sending you. Unless it's a PRI, you will have to use debug
    voice ccapi inout. Unfortunately, the output from this is very
    verbose, and very difficult to read. If it's a PRI, debug isdn q931 is
    much easier to read, and will give you the information you need.

    If it's a CAS T1, a FXS port or (I think) an E&M port, Ask your PBX
    vendor if there's an access code for the trunk. If you dial the access
    code, you should get dial tone grom the gateway. You should then be
    able to dial your extension. If the call goes through, then it's a
    problem between the digits the PBX is sending you, and how your
    gateway is configed.
