For travelling, no SIP based device will be "configure and forget".
Perhaps if you travel only within the US, you may be lucky most of the
time but pretty much anywhere else where IP addresses are scarce you
will be out of luck.

I have been travelling a lot on all inhabited continents, using hotel
provided internet connections, internet cafes, client's office LANs,
hotspots in public places, cafes, airports etc etc.

The most common experience is "SIP doesn't work at all" and the second
most common experience is "SIP only works after messing around a lot".
Even if you get SIP to work, you are likely to spend so much time on
fiddling with settings that it has a negative impact on your schedule.

I haven't used an IAXy yet but I run Asterisk on my Powerbook and use
IAX to connect back to my company's Asterisk server. That works all
the time and is "configure and forget". I assume it will be the same
when using an IAXy.

The only situation I can think of where the IAXy alone will not work
is with hotspots that require you to log in from a web browser in
order to activate the service, probably setting a cookie or something
like that. In this case you would need to run your IAXy on a NAT
provided by your notebook because the hotspot will not give you access
unless it sees the cookie or the MAC address of the machine that was
used to first sign in.

hope this helps
