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

Dear friends,<br class="">
<span class="Apple-tab-span"> </span>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”).<br class="">
<br class="">
<span class="Apple-tab-span"> </span>Unfortunately I got debug
message like this:<br class="">
<br class="">
<span class="Apple-tab-span"> </span>ERROR: rtpengine
[rtpengine.c:1710]: send_rtpp_command(): can't send command to a
RTP proxy<br class="">
<br class="">
<span class="Apple-tab-span"> </span>ERROR: rtpengine
[rtpengine.c:1746]: send_rtpp_command(): proxy
<udp:10.109.247.90:7723> does not respond, disable it<br class="">
<br class="">
<span class="Apple-tab-span"> </span>ERROR: rtpengine
[rtpengine.c:1616]: rtpp_test(): proxy did not respond to ping<br class="">
<br class="">
<span class="Apple-tab-span"> </span>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?
