Hi all experts!
I'm in the process of changing our telecom central to a newer system which runs SIP directly (through the firewall), instead of a separate SIP box.
I am a newbie to Cisco ASA, and know nothing about the so-called SIP. I've received information regarding which ports to open, and the public IP's I must allow in the firewall.
My question is: What do I do regarding priority of the SIP lines. Do I have to configure anything in the ASA, or will it automatically detect this so-called SIP trunk and do priority?
