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.
