I am hoping someone can provide useful information as to how this is supposed to be used. What I have: an asterisk (pbx in a flash) server behind the ASG. UDP/5060 and UDP/10000:20000 forwarded to the pbx with a DNAT rule. I have a QoS rule giving precedence to traffic marked as low delay from the pbx. I haven't seen any posts recently that really talk much about the SIP helper, although I get the impression from a post of Gert's from a couple of years ago that if I used this, almost all of the config stuff would not be needed. Can anyone clarify this?
