[asterisk-users] Issues with call dropping

[Nick Awesome]

Hi guys, have really annoying problem with trunks when I calling over voip provider..


after awhile provider sends INFO packages but for some reason Asterisk doesn’t answer on it.
after 8 packagers provider just drops the call, here is the package

<--- Received SIP request (555 bytes) from UDP:192.168.53.1:5060 --->

192.168.53.1 - operator IP
192.168.53.9 - asterisk IP


Any idea how to fix this?
