Hi!
This sounds like a pre-configured conference group, where you dial into
a conference, and then the conference server invites all the other
participants. The problem is, that you have to wait until all
participants have accepted the call before you start speaking.
Maybe a nicer solution would be the PoC (PTT over Cellular) Service,
which was recently published by several cell phones manufacturer. This
service allows you to use SIP/RTP enabled cell phones in a walky-talky
like mode. Info and the specification can be found at:

Subject: [Serdev] SIP "braodcast"
Hi Jiri, Jan, Raphael and all other Ser users and developers,
--------------------------------------------------------------
as I have already mentioned the demining scenario in our
project there is the need of a Voip SIP "broadcast"
functionality. This means the resonsable operator should be
ready to reach the whole demining group
with one call. Because we do not have real braodcast like VHF
radio a approach could be the following scenario:
The operator will send a SIP invite to all members of his
team and when the user ansers the phone call the call will
automaticly transfered to a SIP conference. This is what I
have discussed with Raphael. What do you think how to realize
such a "broadcast" functionality ??
regards
Olaf
