Why are you loading rtpengine module first :

# loadmodule for RTPENGINE
loadmodule "rtpengine.so"
and later on do this:
#!ifdef WITH_NAT
loadmodule "nathelper.so"
#!ifdef WITH_RTPENGINE
loadmodule "rtpengine.so"
#!else
loadmodule "rtpproxy.so"
#!endif
#!endif

doesn't make much sense...

Same here, though this is more consistent with WITH_NAT check above:

#!ifdef WITH_RTPENGINE
# ----- rtpengine params -----
modparam("rtpengine", "rtpengine_sock", "udp:127.0.0.1:2223")
#!else
# ----- rtpproxy params -----
modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7722")
#!endif

but the following line is also unnecessary:

# RTENGINE MODULE
modparam("rtpengine", "rtpengine_sock", "udp:localhost:2223")

On :
if (is_method("INVITE")) {
setflag(FLT_ACC); # do accounting
}

You should add in T_RELAY route (for example) a call to rtpengine_delete, to free up RTP ports once the call is cancelled or terminated

if(is_method("BYE|CANCEL")) { # if(check_route_param("proxy_media=yes")) { rtpengine_delete(); xlog("L_INFO", " RTPEngine Delete from BYE|CANCEL message in route(RELAY)!"); # } }

Add in failure_route a call to rtpengine_delete() call, to free up RTP ports once the call is cancelled or terminated

You should also set the advertising IP address (the public IP address?? the VPN IP address?? not sure...)

Also, the script seems too complex for your needs. Do you need REGISTER? do you need route PRESENCE? and route LOCATION?

Hi @Sergio Charrua,
