[SR-Users] rtpproxy does not response, disable it

[Zodiac]

Hi, I am very glad that you can answer me for that.

I’ve already set modparam("rtpengine", "force_send_interface", “10.109.247.80”) in my kamailio.cfg from the very beginning.

The port 7723 on 10.109.247.90 which rtpengine daemon runs is not blocked by firewall.

There is nothing prompt out on command “kamctl fifo nh_show_rtpp all”

There is nothing captured on "ngerp -W byline -d em1 port 5095” on Kamilio machine.

There is an prompt “404 rtpproxy not found” on command “kamctl fifo nh_enable_rtpp ump:10.109.247.90:7723 1”

What other reasons can there be for my case?

Furthermore, 10.109.247.80(Kamailio) and 10.109.247.90(rtpengine daemon) are both private IP address, not public address. Dose this affect?


This is the kamailio.cfg portion:



This is the rtpengine daemon startup config:

For example, I set Kamailio on a machine with IP address:10.109.247.80, and launch rtpengine daemon on another machine with interface parameter as 10.109.247.90 and ng port 7723. I set parameter in Kamailio.cfg with modparam(“rtpengine”, “rtpengine_sock”, “udp:10.109.247.90:7723”).

And Kamailio can work functionally under this situation. rtpengine daemon can receive ping message from Kamailio and rtpengine daemon can work as suspected. So for the later case, is it supposed that Kamailio be in the same machine with same localhost address? Otherwise, what’s the reason for my ERROR?
