[SR-Users] RTP Proxy to integrate with kamailio

[amar Smart Telecom]

HI,

 

1.       In wireshark we can check the OK message for parameter ‘C’. If RTPproxy is used the IP shall be that of the server.

2.       In the wireshark if we see the RTP packets shall be between server and the SIP clients. If rtpproxy is not used, the RTP packets will be directly between two clients (although the SIP messages will be between the server and the client).

 

Regards

Hi Daniel,
Your suggestion helped me a lot.Thanks.

But now i am running both rtp proxy and kamailio on same computer(i.e. localhost) and according to syslog there is no error.
Further will you tell me how can i test that they are working together or not, like in wireshark or any other method to trace out their signals.
How should i proceed furher now?

Hello,

you need to configure rtpproxy to listen on udp:192.168.5.97:7722 for control commands, not on 127.0.0.1:7722. The 127.0.0.1 network interface is available on inside same system, not from a remote system.

Cheers,
Daniel

Hi friends,
Its been two days and still finding a way to install rtp proxy and integrate it with kamailio.
I have checked running status of rtp proxy by netstat command in this way...

#netstat -pln | grep rttpproxy

 

and i got the output like that(i assume its working):

 

udp  0  0  127.0.0.1:7722  0.0.0.0.*:


Well here is my setup of kamailio and rtp proxy...

1.I am using two computers one for running kamailio and another one for rtp proxy.

2.Both are running seperately.
3.Two android mobile phones to test the service(App using imsdroid).

I am little bit confused with ip settings in kamailio configuration file in the part where rtpproxy_sock

is given.For now i have given the ip:port of the computer on which rtp proxy is running separately.

And i am getting the error message in syslog like this

can't send command to a RTP proxy

 

proxy <udp:192.168.5.97:7722> does not respond, disable it

 

can't get version of the RTP proxy

 

Actually i want to record the calls.

Any kind of help to configure kamailio with rtp proxy is appreciated.
