Lately, our asterisk server has been experiencing additional audio during conversation.
after much research, I realised that it could be something call RTP injection or RTP sniffing.
I am trying to explain to my boss the possibility of being hacked and advice him to buy firewall software / hardware, but he is not convince.
I therefore need an expert to setup a RTP injection software / server for me to demonstrate to my boss.
