[Freeswitch-users] how to send messages to all members in a conference via freeswitch?

[ran zhang]

Hi All:

            I'm using Linphone as my VOIP client, i want 1 member to 
send instant messages to the conference and all other members in the 
conference should receive them.

           I can't figure out a way to do this,  Linphone only allows to 
send messages to other members on the contact list, even if Linphone can 
do it, can freeswitch handle this?
