Hi,

I have terminals of video conference which are in public IP ( DMZ). I installed kamailio (4.2) which works correctly, it is also in IP pulique (DMZ). I wish configured the kamailio.cfg file, so that kamailio works in proxy SIP. And declared my CODEC of visoconférence in URI, example: 'DR London@domaine.fr'. 
In what part of the file ( kamailio.cfg ) do I have to make these modifications ? This to avoid the flooding. How possibly write the rule of corresponding ACL.

Thank you for your help.

Best Regards,
