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:
