first of all, NAT-triversal depends greatly on which VoIP protocol you are
using.
Astiersk' native IAX2 does veryw ell in this case, SIP will probably work
too.

It also depends on the otehr site (the VoIP provider).

http://www.voip-info.org/tiki-index.php?page=Asterisk general docs
http://www.automated.it/guidetoasterisk.htm some general notes and
config-stuff for www.freeworlddialup.com

Don't be too overwelmed as Asterisk can do too much for what you need :)
look at exten.conf and trhough everything out you don't need.

only thing you need is probably a line saying dial,console (and the
appropriate alsao ro oss config)
and lines to dialout to yoru VoIP-provider (and vociemail if you are
feeling up to it :) ).
