[Asterisk-Users] [PATCH] allow announcements in app_dial

[Brancaleoni Matteo]

Hi.

Since a customer requested us that feature, I wrote this
little patch for app_dial to allow to play an
announcement to the called party, as soon he answers.
you can define the file to play in the dial() option,
using A(filename).
for example:

exten => blah,1,Dial(Zap/blah,30,rA(/my/own/announce)Tt)

that doesn't break anything ...
feel free to blame me for anything bad this patch could do ;)

if for the list is ok, I'll submit to the bug tracker, under
a feature-request.

Matteo
