Is SIPROXD still needed in 2.0?

Okay, so STATIC works if you have only 1 Asterisk server. Or you don't even need static port since pfSense does the re-writting on all ports except for SIP and stuff need for VPN. That is per book. If you have more than one Asterisk server and that is what I am working on right now then some tingling is needed. To complicate things more, also one of my Asterisk servers accepts clients from Outside.
But I think I am getting my way into RTP ports now and restricting each Asterisk to 1000 UDP ports for RTP and hence I should be able to handle 250 channels with 1000 ports.
1- I would love to hear some comments on my previous post please.
2- Does anyone know why 4 UDP port is used for media with a single call? Is that part of the SIP RFC?Thanks

That is cool. However, why do I have to setup 10000-20000 for NAT PORT FORWARD to my Asterisk server which sets behind pfSense v1.2.3 for the both way audio to work?
Because the phones initiate the RTP, if you have remote phones and want the RTP to get in from outside you have to open that. If you're just communicating outbound through a normal SIP trunk to an outside provider, you don't, as everything comes in over the connections initiated outbound.
