I have CUCM 9.1 and customer request is to:
group A - some phones
group B - rest of the phones
A calls B - calling party number is masked
A calls A - calling party number is untouched.
I tried to:
put calling party transformation of A sources on A phones settings level, but this masks all calls from A group (either to group A or to group B),
there is option of calling party transformation for incoming calls (on the phone settings level). So I put different CSS defining A sources and keeping
identification but as transformation is made whe call leaves the phone A you probably cannot influence source again when call comes to phone
to group A.
Dont you now how to setup phones in order to follow requested function (preferable via transformation patterns). I dont want to make another tranlation patterns...
