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:

Hi Zodiac,
1. Can you see your configured rtp node on: "kamctl fifo nh_show_rtpp all" ?
2. Can you ngrep the commands being sent by kamailio to rtpengine?(on both kamailio and
rtpengine machine)
3. Do you have some firewalling rules that may block that 7723 port?
Stefan

Dear friends,
I am working on a program on Kamailio and rtpengine proxy. I am wondering whether can I
set Kamailio and rtpengine daemon on different physical machines. 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”).
Unfortunately I got debug message like this:
ERROR: rtpengine [rtpengine.c:1710]: send_rtpp_command(): can't send command to a RTP
proxy
ERROR: rtpengine [rtpengine.c:1746]: send_rtpp_command(): proxy
<udp:10.109.247.90:7723> does not respond, disable it
ERROR: rtpengine [rtpengine.c:1616]: rtpp_test(): proxy did not respond to ping
And, I also tried to set Kamailio and rtpengine daemon in a same machine,and use
modparam(“rtpengine”, “rtpengine_sock”, “udp:localhost: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?
