[SR-Users] Kamailio-5.3.3. NAT and RTP not working

[supreeth herle]

Hello Pavithra,

Have you tried advertising the floating IP of the VM running RTPProxy as
follows?

Edit /etc/default/rtpproxy file as follows:

# Additional options that are passed to the daemon.
EXTRA_OPTS="-l 172.24.15.30 -d DBUG:LOG_LOCAL0"

here, "-l <PUBLIC_IP>"

Hope it helps.

Regards,
Supreeth
