Hi Tito,

A SIP call can have only 2 end-points. What is not clear for me is: 
after inserting the media server, what is the final configuration in 
terms of who's talking to who? Still A talks to B, but media server is 
recording ? or A talks to media server (like VM) and B drops out ?

Best regards,
