Ok let us solve this with my kamailio 5.1.4 version in ubuntu server.
I have installed rtpproxy by apt-get install rtpproxy.
i have edited "/etc/default/rtpproxy" file with the line 'EXTRA_OPTS="-F -s
udp:127.0.0.1:7722 -l 34.201.122.249 -d DBUG:LOG_LOCAL0"'
i have edited "/etc/init.d/rtpproxy" file as follows,
DAEMON=/usr/bin/$NAME
PIDFILE="/run/$NAME/$NAME.pid
I have provided "#!define WITH_NAT" and "modparam("rtpproxy",
"rtpproxy_sock", "udp:127.0.0.1:7722")" in my cfg file.
started rtpproxy "service rtpproxy start"
when i try "netstat -tulpn | grep rtp" it shows
udp 0 0 127.0.0.1:9000 0.0.0.0:*
1422/rtpproxy
So i think the rtpproxy is currently running fine.
Now we can go to kamailio part. I have attached my cfg file in this mail.
Ip addresses of my client servers are named as dummy.
I have gone through the document "
https://www.kamailio.org/docs/modules/5.0.x/modules/rtpproxy.html" to set
up rtpproxy in the cfg file.
checking the rtp ports "kamcmd rtpproxy.list" showing
{
setid: 0
url: udp:localhost:12221
index: 0
disabled: 1
weight: 1
recheck: 14661928
}
{
setid: 0
url: udp:127.0.0.1:7722
index: 1
disabled: 1
weight: 1
recheck: 14661928
}
I have enabled rtp proxy using "kamcmd rtpproxy.enable udp:localhost:12221
1" "kamcmd rtpproxy.enable udp:127.0.0.1:7722 1".
So i think ports are ready for rtp proxy.
Now i will explain the call flow. please take a look at my cfg file. I have
enabled log using L_BUG.
when i try a call from hangout number through my twilio trunk to my
asterisk freepbx extension,
set_rtp_proxy_set("1"); giving true value. But rtpproxy_offer(); giving -3
as result. And also my header is not changed. As a result actuall rtp is
going end to end between asterisk and twilio not through kamailio. Please
help me with the details.
