Hi Experts,
         I am working on a call flow where one of the video endpoints joins the video call while the call is in progress. RTP is used for media.
So we trigger RTCP FIR packet to the existing video endpoints in the call when a new user joins.
To mitigate UDP packet loss, we are planning to have a retransmission mechanism for the RTCP FIR packet.

I am looking for inputs on what should be the frequency and how many times we might have to retransmit the RTCP FIR packet.
I know it would be greatly dependent on the network as such, but wanted some kind of default value that would mostly suffice.

Regards,
Priya
