style='font-size:10.0pt;font-family:Verdana;color:blue'>I think Asterisk should
have no problem with NAT, even when used with SIP. I mean just listen for the
first RTP packet and send the stream where it comes from (that’s called symmetrical
NAT). I think everybody is doing it like this now and they are selling their
stuff for thousands and thousands of dollars.</span></font></p>

<p class=MsoNormal><font size=2 color=blue face=Verdana><span lang=EN-GB
style='font-size:10.0pt;font-family:Verdana;color:blue'>Well we do try to look
over our shoulders. There is a lot of tempting stuff out there, and making
decisions is difficult. At the moment I think it would be a mistake for us to
start another development branch. We simply have too many open issues with SIP
already. We hope to have a great phone (some day.-) that fits Asterisk pretty good
although it’s just using SIP…</span></font></p>
