Hi all. I'm trying to setup Asterisk to act as a purely SIP PBX for Internet based VoIP. I've got it configured with with a couple of users in sip.conf like so: [andrew] type=friend username=andrew secret=<secret> host=dynamic defaultip=192.168.26.21 dtmfmode=inband Calls addressed as 'sip:username@asterisk.server' or 'sip:extension@asterisk.server' work fine from unregistered clients and for the registered ones a simple username/extension works like a charm. But, I haven't worked out how to let the registered SIP clients access anything outside of Asterisk. E.g. if they enter 'sip:user@someother.server' they get 'Session rejected: 404 Not Found' I'm sure it's obvious and is simply solved, but I'd love a hint :-). So then there is the million dollar question. Once this is working on the test network can I make this work with a NATed connection to the Internet. All registered clients are on the same network as Asterisk. I would like to setup a static/destination NAT on the firewall to point the appropriate (but limited) ports to the Asterisk server. Obviously Asterisk would have to also be set to use the right IP in outgoing packets. Is this going to be possible? Regards, Andrew Radke
