I have installed kamailio 5.1.4 version in ubuntu server. I need to route
RTP packets through kamailio with SIP packets. I will explain the way i
have set up everything.
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 0 127.0.0.1:7722 0.0.0.0:*
1437/rtpproxy
So i think the rtpproxy is currently running fine.
Now we can go to kamailio part.
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:127.0.0.1:7722
index: 0
disabled: 0
weight: 1
recheck: 0
}
I have enabled rtp proxy using "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. 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 -1
as result. syslog shows some errors like below,
Aug 13 10:28:57 ip-172-30-0-10 rtpproxy[1437]: DBUG:handle_command:

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.

Hello Anoop,
I am not an rtpproxy expert. But I would suggest that you look into the error
quoted above. This means that rtproxy can't bind to the respective port and or
address. There are several possible reasons for that:
- this IP is not configured (correctly) on the server
- the port is already allocated to another process
- there is some other error in network configuration
Best regards,
Henning

Are your ports open?

I do not know how to make that ports open. I am using aws EC2 instance as
server. So when i open the specified port and reboot my server, this error
telling me that again it can not bind with a new port. Each time it
changing the port.
Shall i provide my cfg file here? Can you guys check it and tell me what is
wrong in it?

Hello Anoop,
have you checked that the IP address configuration also is ok? Regarding this
ports issue you should probably refer to the documentation or support of the
particular cloud provider.
Generally speaking - you could provide your cfg here, sure.
But another option would be to simple test your setup on a local (not AWS)
machine. This way you can see if the issue is related to your cfg, Kamailio,
AWS or something else. This would be my suggested next step.
Best regards,
Henning
