u could make a trik
for example lets say ur outgoing calls with Client matter code on the route pattren is
9.XXXXXX
and u have discard pre dot
make another route pattren and make it without Client matter code
for example
8.XXXXXX
also put discard pre dot in the called number transformation in the route pattren setting page
and in thecall forward put the one start with 8
good luck
