where and how to use translation profiles

Unanswered Question

Looking at doc #64020 I can see that translation profiles can be added to dial-peers, voice-ports and even controllers. This is good to know but one thing that the doc does not cover is how and when to use the different techniques. For example, assuming that I have trans profiles on all three, which order are they applied? Or does one override another? In the case of using a trans profile on a dial-peer how do the prefix and forward-digits commands affect the translation? Any help and ideas would be greatly appreciated.


Thanks,

Diego

Hi


"Voice translation rules are associated with voice translation profiles. Using a voice translation profile gives you flexibility and

scalability by allowing the use of multiple voice translation rules. You can apply voice translation rules to called, calling numbers in the same translation profile. And yes it's typically associated with a dial-peer or a voice port or trunk group.


Where the voice translation profile is applied affects the matching of inbound and outbound dial peers.


A profile that is applied to a voice port is carried out before the inbound dial peer is matched.


A profile that is applied to an inbound dial peer is carried out before the outbound dial peer is matched.


A profile that is applied to an outbound dial peer is carried out before the call is transmitted."



This explanation is included on the Cisco Voice Gateways and Gatekeepers book Chapter 10 Digit Manipulation. Authors: Donohue, Mallory and Salhoff. Available at ciscopress.com. It's quite good and has couple of examples.
