Hi all,
How can I implement a full-featured Call-Waiting behavior on the Asterisk level
(e.g. I don't want to relay on end-equipment capabilities)?
I found it very strange that such a basic feature is not built-in in Asterisk
(and I've googled a lot in search for this).
Here is what I need:
If you use zap then asterisk already does it. With sip the phones will
not tell asterisk about the hook flash. However you can play around
with dynamic features and assign a key that will mimic hook flash.
Injecting the beep sound might be hard though. Playing a different
ring to 2nd caller based
