[SR-Users] Kamailio and Asterisk in K8s

[David Villasmil]

So here's my rtpengine conf:

[rtpengine]
interface=internal/[PRIVATE_IP];external/[PRIVATE_IP]![PUBLIC_IP]
foreground=true
log-stderr=true
listen-ng=[PRIVATE_IP]:22222
port-min=23000
port-max=32768
recording-dir=/tmp
recording-method=pcap
recording-format=eth
log-level=6
delete-delay=0

and in Kamailio, you listen on 2 ports, one for the public side, the other
for the private:

listen=LISTEN_PRIVATE_PROTO:LISTEN_PRIVATE_IF:LISTEN_PRIVATE_PORT advertise
ADVERTISE_IP:ADVERTISE_PORT
listen=LISTEN_PRIVATE_PROTO:LISTEN_PRIVATE_IF:5080

This is basically my setup, it should be straightforward.

Hope that helps
