[SR-Users] kamailio + asterisk + webrtc
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, I am using this command for starting RTPengine - /usr/sbin/rtpengine --table=0 --interface=192.168.1.x\!182.75.xx.yy --listen-ng=127.0.0.1:2 --pidfile=/var/run/rtpengine.pid --log-level=6 --log-facility=local1 in kamailio.cfg --> listen=MY_SIP_ADDR advertise 182.75.xx.yy:5060 But still there is no RTP from outside network. Still not able to sort out what is the issue.If pfsense is blocking rtp packets or any other. but i have very config on pfsense.

Hi Daniel,
Within a network above tech stack is working fine for VOIP calls.
But when i am trying from outside there is no sign of RTP.
Cmd for rtp -
/sbin/rtpengine -p /var/run/rtpengine.pid

5 -M 55000 --log-level 6 --log-facility local1
106.51.78.78 - public ip
192.168.1.249 - priv ip (kamailio + RTPEngine)
Kamailio config when call is b/w WebRTC --> WebRTC
rtpengine_manage("trust-address replace-origin replace-session-connection

[SR-Users] authentication using auth_db module
Hi all, I'm trying to establish mysql database connection inside request route (at runtime) based on the type of user, as credentials are stored in multiple databases (may be different servers) for the users. Therefore, I am trying to find out that is there anyway to connect to mysql dynamically in request route or pass 'db_url' parameter dynamically to auth_db module. Hope this explains the requirement. Looking for suggestions. With Regards, Arish ___ Kamailio (SER) - Users Mailing List sr-users@lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
Re: [SR-Users] authentication using auth_db
Hi David, Thanks for the reply. I checked out sqlops module, this will solve the problem only when I get the authentication password (secret) of the user inside request route. For this I tried checking kamailio pseudovars but haven't found one. Therefore, I am sticking with auth_db module.If this is possible by any other way do let me know. thanks, Arish ___ Kamailio (SER) - Users Mailing List sr-users@lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
Re: [SR-Users] authentication using auth_db
Hi David, This can solve the issue but depth(records) of that view would be too much. The architecture is like this: One kamailio fronting multiple asterisk. Each of asterisk boxes have their Specific users databases. Thus, I'm trying to create db connections inside request route or completely write my own authentication service if I get the user's Password. So, that would be great if I would be able to pass the db_url to auth_db module in request route. Let me know what you think.
