Hello list,

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 reliable?

Kind regards,

Thank you,
