Re: Incoming Digit Converter

There are a number of ways you can do this. One easy way to do this is in the gateway configuration in CallManager, check the Sig Digits box and set the Number of Digits to 3.

Sorry, I assumed that you meant you wanted to convert 4530 to 530.

Another way you could do this instead of what I said before is to configure Translation Patterns in the CallManager. For example, go to Route Plan -> Translation Pattern. Set the pattern to 4530 and set the Called Party Transform Mask to 623

Then repeat for however many numbers you have.

Or if you have a relatively small number of these to do (I think the limit is around 250) then you can perform this in the router. An example would be:

num-exp 4530 623

And repeat this for however many translations you have. Note that if you do it this way then the voip dial-peers should point to destination-pattern 623 (not 4530) because the num-exp takes place before the dial-peer routing. If you do it the other way then the dial-peer would point to 4530 and the CallManager would do the translation.
