Translation Profile is used on Voice Gateway to perform Digit Manipulation on the Calling and Called Parties. The Translation Pattern is doing the same digit manipulation. The translation profile can be applied BEFORE the incoming dial peer is matched (if the profile is applied under the voice port) or AFTER the incoming dial peer is matched (if the profile is applied under the dial peer) But it is always applied after the outgoing dial peer is matched. Now the Translation Pattern on CUCM can be matched before the route Pattern in the outgoing call. and can be matched in the incoming calls coming from SIP trunk or a gateway. The logic is not the same between a voice gateway and CUCM.
