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?

Yes is the easy answer.

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.

Not impossible at all.

You *may* find that some routers don't like it, but the majority of them
are just fine.

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).

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.

Go read this:

http://www.voip-info.org/wiki-Asterisk+SIP+NAT+solutions

(Although I don't think that page is quite correct as
I can make their
'3'
scenario "just work" ...)

You pickup another phone and dial 200.

My office phone is a SIP desk-phone (GXP 2000) which is behind a NAT
router, and is an extension on a "virtual" PBX - a server in a co-lo
facility. I have no problems with accepting calls on it. It uses STUN and
there are no special rules on my NAT firewall to make it work.

On my laptop, I use an IAX softphone (IDEFISK), and its "just works" too.
It accepts calls once it's registerd with the same server, or other
servers, some of which are behind NAT firewalls themselves.

Use the qualify to help, but yes the soft phone registers and the
system sends calls to it.
