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?

Yes, you can certainly run rtpengine on a different host than the
Kamailio host.
Is it possible there are firewall rules on the remote rtpengine host
that are blocking UDP connections from your Kamailio box to port 7723?
That would be my first thought.

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?

You can try make use of the
below parameter:
# Which local interface/IP should be used for the control channel
modparam("rtpengine", "force_send_interface", "X.X.X.X")

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:

I solved this problem by changing the 127.0.0.1 in rtpengine startup config into
10.109.247.90 which is the eth0 address of the rtpengine machine.
Now Kamailio successfully connect to the rtpengine daemon.

I’ve already set modparam("rtpengine",
"force_send_interface",
“10.109.247.80”) in my kamailio.cfg from the very beginning.
Can you try force ping
from kamailio machine (.80) to rtpengine machine
(.90), on 10.109.247.80 interface? (it should work)
There is nothing prompt out on command “kamctl fifo
nh_show_rtpp all”
If there is nothing shown it means that kamailio sees no rtpengine
nodes. What kamailio/rtpengine version are you using? (are they both
latest upstream?!). The sock line should be fine: modparam("rtpengine",
"rtpengine_sock", "udp:10.109.247.90:7723")
Can you increase the log level(debug=3) and send some debug info on
what's happening right after you restart kamailio?(for rtpengine module)
There is nothing captured on "ngerp -W byline -d
em1 port 5095” on
Kamilio machine.
Wehn eventually you see something for the show ctl command, you
should
try capturing for dst port 7723, on kamailio machine, to see the
commands sent to rtpengine.

Hi All,
I am troubling with rtpengine and kamailio services on cent os core7 os, as
these service are not getting started, and when i try to start the services

The answer is actually right there, on your RTPengine startup screenshot (“invalid
interface specification”).
And if RTPengine fails to start because of that error, Kamailio cannot ping it, so the
Kamailio side of it makes complete sense.

Basically check the configuration on both side in terms of how they will
“talk”. When you bring up rtp engine make sure it’s listening on the right
ip:port/socket and make sure kamailio is configured to connect to that
port/socket.
