[SR-Users] Handling of packet loss in the Kamailio to RTPEngine control protocol

Hope you are all well.
Under some load test simulations I've been facing cases where the command
Kamailio sends to RTPEngine times out with such message:
send_rtpp_command(): timeout waiting reply for command "" from RTP proxy
After checking RTPEngine logs, I can see the command was received and a
reply was sent, so I am thinking the reply packet could have been lost
somewhere in the network (they are in different servers). So my question
is, how resilient is the RTPEngine NG protocol to handle packet loss
situations? I saw TCP is not supported, so are there UDP retransmissions in
place to guarantee packet delivery? Any ideas to make this connection more
