Hi Llandry,
It's easy enough to change.
look in
/etc/e-smith/templates/usr/local/operator/op_server.cfg/30-out
It's about halfway in - code looks like this...
; Formatting of the callerid field
; where 'x' is a number
clid_format=(xxxx) xxxxxx
Change to whatever is best for you, do a commit, that should do it.
Best
S
