Hi All;
Did anyone try to use IAX IP Phone behind NAT, and let
it receive calls from Asterisk without doing port
mapping at the router existed at the site where the
IAX IP Phone existed? Is the need just to let the IAX
IP Phone that is NATed to register on the Asterisk and
at asterisk I set nat=yes for the IAX client
configuration?
Or it is impossible to let the NATed IAX to receive
calls without doing a port mapping at the router?
What about SIP, any luck?
Regards
Bilal

I do this all the time fromn my laptop at friends/colleagues/other locations where I get a broadband connection, and don't ever fiddle with their routers.> Or it is impossible to let the NATed IAX to receive > calls without doing a port mapping at the router?Not impossible at all. You *may* find that some routers don't like it, but the majority of them are just fine.> What about SIP, any luck?Same again, it "just works". Not router fiddling required. I visit client sites with a small number of differnet SIP phones - plug them into their network and let them make calls, and unless they have weird routers with broken SIP ALGs or strict firewalling, it "just works". We've been through this with you recently. Are you not getting list emails? What about google or the VoIP WiKi? There is plenty of stuff there all about it. I can easilly make SIP calls from SIP phones behind a NAT router to an asterisk box behind a different NAT router. It just works and there is a good page on the VoIP WiKi all about it.

Hi Gordon; They are able to receive calls? Origination is not a problem I know, but what about receiving calls from the Asterisk to them? For example, how I can call the extension 200 that is behind NAT? (Assuming that extension 200 is registered on the Asterisk).
