Hi.

I have a beginner conceptual question about Asterisk:

Let's suppose that there are 4 softphones registered in my Asterisk and all of them are currently online. In addiction , there is no call.

Suddenly, one of these softphones sends a SIP message to the Asterisk. In this case the dialplan will execute the instruction ' exten => 2005,1,Dial(SIP/2000&SIP/2001&SIP/2002, 30) '

All softphones (2000, 2001 and 2002) will ring. These are proprietary softphones and all of then will reply with SIP 183 message. SIP 183 will contain SDP with media information.

The question is:

Will the caller receive SIP 183 from each callee? That is, will it receive 3 SIP 183 messages? It is important to the caller receives a SIP 183 message from each callee, because this caller needs to send early media (video) to every callee.

Or, will Asterisk send just one message SIP 183 to the caller, with some kind of generic SDP message?

Any hint will be very helpful!

Thanks a lot.
