[asterisk-users] Dealing with progress codes

Wed Oct 29 23:08:25 CDT 2008

Arka:
I thought you would reroute the call with (or without) the leading one, so,
just Dial again.

This will work and your users wont notice a BIG difference if the call is
answered. The problem is if the call is not answer, because if you have a
busy number, then your users will get something like "ring, ring...ring,
beep,beep...".

For a better solution I would recommend you to get at least your local
prefixes and use the correct dial string with patterns. This can be achieved
with a script.
