I would like to change the caller-id of a specific phones when he do a PSTN call.
I understand that I can do this with a route pattern..
is there any way to change it straight on the phone without playing with the CSS, just like changing the "party mask" or something like that
You change the ANI you send in:
External phone party mask
If you use the external phone party mask it changes it for any call that is made thru the RP with that checkbox
You can try using a translation pattern to modify the ANI as well.
In any case if this is only for a set of phones (or 1 phone) it requires you to play with CSS and partitions.
if this helps, please rate
