I took some time to gather nformation.

Having multiple RTP receivers is not a problem.

The SRTP master key must be conveyed to each receiver (sharing all the same key).

I want to ask how the mechanism that occurs when the linphone source has to send the srtp packet to more than 1 linphone receiver? Is srtp_protect done once and then duplicate as many receivers? or is srtp_protect done for each different receiver?

If I want to know the target of the packet sent (linphone receiver), what variables can be accessed from the process_on_send method in the ms_srtp file that store target identifier ?

Note: the target can be the ip address or sip number of the receiver

Thank you
