[cisco-voip] H.323 DID forward internal Ext

There's a bunch of different ways.

Somewhat depends on what you get from Telco for digits.

I usually only get 4 digits from telco

so I would do something like this:

num-exp 5566 1919


You can get fancier and do pattern matching (using RegEX) like this:

num-exp 55.. 19..

So 5566 would be translated to 1966

You could also add and remove digits

num-exp 55.. 5519..

That would take 5566 and make it to extension 551966

Did this help?
