It can easily modify your external calling party number.

Here is my dilemma.
All the phones in my callmanager 4.0 setup do not have "external phone
number mask" setup.  Instead, I have put the number mask in to the
translation pattern for outbound calling. For example.
My extension is 4990
I dial a call that matches the 8.@ route pattern, and the call gets
routed out the PRI Gateway, and the pattern applies the "Calling Party
Transform Mask" of 323860XXXX
This results in the caller-id showing up as 323-860-4990. Perfect.
Now here are the problems with this solution. If I enable callforwarding
on my phone (sending them to my cellphone), the caller-id gets messed
up. Here is why:
Let's say my friend at 310-833-5625 calls me on my cisco phone. The call
hits the phone, but there is a CFwdAll set.
The call forwards to 813239438833 (my cell with the outgoing prefix of
8).
When the call forwards, it runs through the route pattern 8.@
The call exits the PRI Gateway, and the Calling Party Transform Mask
applied is 323860XXXX.
The call reaches my cellphone, and the caller-id says 323-860-5625
So, only the last 4 digits are from the original callers phone number,
and the rest are from the route pattern's transform mask.
Needless to say, this is a problem.

One solution I have found is to eliminate the "Calling Party Transform
Mask" from all route patterns. Then, I add an "External Phone Number
Mask" to each and every line on my phone. This way, when I call out from
my phone, the caller-id is correct, and calls forwarded through my phone
retain their caller-id when they go through the route pattern. This is a
serious maintenance nightmare, as I would have number mask's all over
the place. However, the upside of this route, is that the 2 people in
the office who want caller-id blocked on their outbound calls can do
so...(anyone know an easier way?)

I know other people have had to deal with this, but I cannot find the
answer in my archives of this mailing list.

Have you ever dealt with this, and do you have a solution that will
allow me to keep the number masks in the route pattern?
