I tried advertising udp port like this listen=udp:192.168.1.x:5060 advertise 182.70.xx.yy:5060.

How to advertise RTP ports?

Kamailio+RTPengine on a Centos s/m with a priv ip - 192.168.1.x

Asterisk is on another CentOs s/m with a priv ip - 192.168.1.y

pfsense on pub ip - 182.75.xx.yy 

PORT FORWARDING on pfsense-

 sip and rtp ports to kamailio+rtpengine server 192.168.1.x.

Config and logs are attached.

Thank you for the reply!

With Regards,
