No Audio at all! what went wrong?

General Help

Guys, I am not sure what has gone wrong but I have no audio either way on outbound, inbound or internal calls. To top it off the line gets hung up on presumably for a lack of audio.
Can anyone point me into a direction please? I even loaded a backup so I presume a system file got messed up or something and this time I do not think it was something I did…lol

Asterisk v 1.8.4.2

Weird, ok you can stand down… I guess it must of been me! I was working adding in the iSymphony system and added a part to the iptables that got crammed in the middle of the failtoban stuff.
Anyway I removed it and now its working again, I don’t know why that would stop my audio but it did, all is well now and working as it should.
