[cisco-voip] route patterns/callerid mask/callforward

[IT]

But that wont fix the problem. I want to see the actual callers
caller-id. The original callers cell phone number will now be covered up
by the telco with my companies main number. Many people here forward all
their calls to their cellphone, and this basically eliminates caller-id
for them...

A really easy fix for this problem is to call your Telco and request a
'screening range'.

They can populate a screening range with all the DIDs on your PRI. 
Then whenever an outbound call is placed from your site the Telco
checks the ANI that CallManager is sending.  If the ANI is a valid DID
then it is passed without modification.  If the ANI is something
outside of your DID range then the telco overwrites your ANI with your
main phone number.

All the major telco's I've dealt with support the screening range
concept in one way or the other.

Of course, a side effect of this problem is you can no longer prank
your friends - and other legitimate things such as wanting to send out
a toll-free number as your ANI.

the phones external calling mask or the route pattern mask? I don't use
wildcards, I simply populate the field with our main number. If I have
the external mask set per phone, I will see the original caller's
number, but if I use the mask on the RP I will see my main number?
