Subject: [Sipping] Call and call-id

Hello,
 
I have a doubt concerning the definition of a call-id.
I read that a call "consists of all participants in a session invited by a
common source".
I understand that one INVITE request (and so one call-id) may result with
several call-legs due to forking.
My question is :  
 Is it possible to use the same call-id in 2 differents INVITE requests to
2 differents User Agents ? 
 
Let say User Agent A invites User Agent B and user Agent C. Will it use the
same call-id in the 2 INVITE requests, is this allowed ?
 
Thanks for any help,
Marie-Noelle.
