[SR-Users] Kamailio 4.4 + rtpproxy behind the NAT (debian stretch 9.13)

Fri Oct 1 20:29:16 CEST 2021

Dear all,

I just compiled the rtpproxy from sippy github repo.

I have installed the rtpproxy with advertise.

Now, when trying to start kamailio, I have those errors :

 /usr/sbin/kamailio[784]: ERROR: rtpproxy [rtpproxy.c:1060]: child_init():
> Name or service not known
>  /usr/sbin/kamailio[784]: ERROR: <core> [sr_module.c:922]:
> init_mod_child(): Error while initializing module rtpproxy
> (/usr/lib/x86_64-linux-gnu/kamailio/modules/rtpproxy.so)
>  /usr/sbin/kamailio[784]: ERROR: <core> [pt.c:328]: fork_process():
