[Asterisk-Users] ignorepat changing the sound of dialtone

[Andy Hamilton]

This depends on what kind of phone you are using.
With most (any?) SIP phones, nothing will be sent by the phone to the
server until it actually dials (whereas Skinny phones sent out on/off
hook and digits realtime).

If you're using a Cisco phone with a sip image, my guess is that you
can set something in dialplan.xml (or whichever file it is that the
Ciscos look at to match numbers).
That way, if you wanted someone to press 0 to get an outside line, the
phone would see that an 0 was pressed and immediately dial.
Obviously, you would catch this in Asterisk. Once *'s gotten the
"call" from an extension that has dialed an 0, an RTP stream with the
phone would commence and * would wait for the number that the party
wishes to call (I believe there is a setting to change the tone...
check your conf files or the wiki; I'm not sure where exactly it is.
Once * matches a dialing pattern, it would dial out.

Hope this helps.
