There are two methods: translation-rule and dialplan-pattern. The first is more powerful, the second easier to configure (single command)\


In both cases you need to know the format the called number is sent, to do that, take "debug isdn q931" with "term mon" for an incoming call.


After that you configure accordingly to the above.

I did one a little differently. My DID range didn't match my extension number scheme so I did this:


ephone-dn 100

mailbox-selection last-redirect-num

number 491

name Incoming DID

call-forward all 104


All calls that come in with digits 491 are forwarded to extension 104.


The mailbox-selection last-redirect-num line makes sure the messages get left in the right mailbox if there is no answer. Without that line, messages would be left in mailbox 491 (which doesn't exist in my system).



If you have lots of phones, you wouldn't want to do this, but I had 10 so it was easier than figuring out a translation rule.


Hope that helps.
