Thank you Daniel.

We tried with -s udp:10.25.1.1:7722, but received the same result.

 

We see in log file of rtpproxy and in tcpdump in Kamailio, that remote rtpproxy send response to all requests from Kamailio.

 

Best regards,

 

Julia

Hello,

from logs, kamailio cannot communicate with rtpproxy. I never used
rtpproxy with -s udp:*:7722, so I don't know if it is valid, you should try with -s udp:10.25.1.1:7722

Cheers,
Daniel

Hello,

I try to run RTPProxy on a different machine than Kamailio (Kamailio IP is 10.25.1.5 without NAT) for rtp recording.

Remote machine has an IP Address of 10.25.1.1 and started with

 /usr/local/bin/rtpproxy -l 10.25.1.1 -s udp:*:7722  -F –P –r/log/rtp_trace

In Kamailio configuration file:

modparam(“rtpproxy”, “rtpproxy_sock”, “udp:10.25.1.1:7722”)

And then, we receive an error after Kamailio start:

/usr/local/sbin/kamailio[24510]: ERROR: rtpproxy [rtpproxy.c:1527]: timeout waiting reply from a RTP proxy

/usr/local/sbin/kamailio[24510]: ERROR: rtpproxy [rtpproxy.c:1536]: proxy <udp:10.25.153.149:7722> does not respond, disable it

/usr/local/sbin/kamailio[24510]: WARNING: rtpproxy [rtpproxy.c:1404]: RTP proxy went down during version query

/usr/local/sbin/kamailio[24510]: WARNING: rtpproxy [rtpproxy.c:1430]: support for RTP proxy <udp:10.25.153.149:7722> has been disabled temporarily

 

In netstat  -a:

udp        0      0 KAMnet-JAF-TST-01:53522     vm-kamnet-dev01.bgtehi:7722 ESTABLISHED

udp        0      0 KAMnet-JAF-TST-01:36633     vm-kamnet-dev01.bgtehi:7722 ESTABLISHED

udp        0      0 KAMnet-JAF-TST-01:32925     vm-kamnet-dev01.bgtehi:7722 ESTABLISHED

 

It works, when Kamailio & RTPproxy are configured in the same machine, with  

modparam(“rtpproxy”, “rtpproxy_sock”, “udp:localhost:7722”),

Is there something wrong in configuration of remote mode?

Thanks for any help,

Julia
