[SR-Users] Call drops after 1 minute

Greetings!

I have a CentOS setup in AWS where all my calls are dropped after about a
minute or so. I realize this typically is a NAT problem, but I can't see
where my error is.
Sound is fine both ways.

Kamailio is set with WITH_NAT and I use rtpproxy like this:
OPTIONS="-l 10.1.2.10 -s udp:127.0.0.1:7722 -d INFO:LOG_LOCAL5 -m 35010 -M
35110 -A 54.171.168.48"
(10.1.2.10 is the local IP for CentOS)

Tested with MicroSIP and Linphone and tried numerous configurations. It
seems the receiving client is not able to verify the call has been set up,
and disconnects. MicroSIP has the status "Connecting..." until it
disconnects.

All tips appreciated. Will post configuration and logs if needed.
Kamailio version 5.6.2 from rpm and rtpproxy 2.1.0 compiled from source.
