[asterisk-users] Messages out of calls. Is it really possible?

[Rodrigo Pimenta Carvalho]

Hi.

I have read in some web sites that ASTERISK can support messages out of calls. What does it exactly means?

1 - Can a dialplan script accept and handle a message from a callee party, even before the call be connected?

2 - Can a ringing callee send SIP MESSAGE to the ASTERISK even before answer the call?

3- Could I use dialplan function MESSAGE() to receive SIP messages from callees, even before the call be connected?

Any hint will  be very helpful!

Best regards.
