Hi Arron,

You're in luck. I've been using sipgate for quite a while but I only
added Asterisk to the mix last week and it's been working fine! My
config is quite minimal so here it is. Note that I'm using the newer
syntax that doesn't require a "register" statement. I'm not sure which
version of Asterisk introduced this but I'm using 1.6.

Glancing at your config, I'm not sure what's missing. I know
insecure=invite is sufficient so you don't need insecure=very. My
situation may be a little simpler though because my server is also my
router so there's no NAT going on between Asterisk and sipgate. Still,
that shouldn't be an issue. I did have to open the RTP ports on the
firewall. I suspect you may have to forward them as well but you've
already done this. Maybe put your server in the DMZ to be sure. It's
not necessary to allow 5060 though unless you want people to be able to
call you directly without going via sipgate. You may want this since
sipgate blocks incoming SIP calls, except from select providers.

Hope this helps,
James

P.S. If you want, I can show you my really nifty trick for fading down
the volume when a call comes in and fading it up when the call ends. ;)
It takes multiple calls into account.
