PFsense has no inherent problems for VoIP. Make sure you’re using an advertised public address for SIP and RTP and also make sure you’re forwarding RTP port range from outside to RTP engine.

Hi all, I am using kamailio as sip server and asterisk as media server behind pf-sense firewall (NAT) with a public ip. Sip signalling as well as rtp packets are flowing correctly when the endpoints are within a network. But when trying from outside network sip signalling is working perfectly but there is no RTP.

Public ip behind pfsense -> 182.70.xx.yy kamailio+rtpengine and asterisk servers are on private ips --> 192.168.1.x kamailio ip - 192.168.1.x asterisk ip - 192.168.1.y

Please, feel free to ask for more information.

Hi Arish,

Can you provide asterisk's sip.conf and example SDP messages related to your calls initiated from outside.

You must use advertised address in kamailio config as below. listen=udp:192.168.1.x:5060 advertise 182.70.xx.yy:5060
