Hi, Freeswitch is sending re-invites in each 60 seconds. And it comes with SDP which causes our WebRTC client on Mozilla browser to stop sending media. Is there a way to tell freeswitch not to send the re-invites with SDP?

If you, for example, used pieces of the original (Vanilla) FreeSWITCH configuration, there are bind_meta_app bindings which send the call into another context ("features"). Once it's done, the user's limit counter is lost, and you need to increment it again in the new context. Also, why don't you implement daily and monthly minute limits and block the user as soon as these limits are reached?

Not by brouteforce on other site and I defenetly use fail2ban. That;s not the issue. I don't have any transfers within meta bind app. I think it was some kind of sip reffer attack. 2014-10-22 6:46 GMT+06:00 Steven Ayre <steveayre@gmail.com>: Also do you know how the password was gained?
