Hi guys.

I'm fairly new at the voice game, and this is my first port of call.
Please correct me on any incorrect assumptions I may make (read: n00b).
Please excuse if this ends up as a repost, as I tried posting this b4, but it's gone unposted for some reason

Current scenario:
I've signed up with WorldExchange (GREAT service/speed, poor billing; story for another day) on their "torrent" pand, and got my "free" SIP account through the VFX.

I use a Linksys WAG54GP2v2 to "dial-up" & keep connection open, host my physical phone line (aka. hw-based SIP client), & act as my first firewall. DynDNS coming soon. So far, so good

Next I have a Endial firewall, that I may scrap in favour of good-ol' IPCop (ol' faithfull). Endian had a facility to act as a SIP gateway/proxy, so that's got me really exited. Squid cache, SPI, DNS, DHCP, blah, blah, blah

Next, on the 'inside' of my network I have a windoze (XP/2k) box (testing, NTFS, all the other cr4ppy stuff it's just easier having a box for), Ubuntu to manage my scheduled torrents via TorrentFlux & act as a media server (SlimServer), and optionally as a Asterisk box (?), source compilation, testing & some other stuff.
I also have a dd-wrt v24 rc6 flashed Linksys WAP54G for my WiFi. Looking ar setting up a Public WiFi in my neighborhood to resell & make some money off my killer connection (via hotspotsystem).

Other clients include my MacBook Pro, Mac G5 & Asus eeePC 701 UME (& then some)

All seems good so far

A few questions arise around my setup.

Can I set up Asterisk on my Linux box to act as a gateway & use Gizmo5 SIP VoIP client to connect through it out to my SIP account hosted by WorldExchange VFX? Would I be able to connect from outside my LAN to my Asterisk box to make international calls with my VFX account?

Am I going about this the right way?
ANy other goodies anyone could suggest for my setup?

Your 2c's worth will be valued

Once you have Asterisk installed you can plug a phone in anywhere on the net and have a remote extension. You just need to ensure you have the correct settings configured since NAT transversal of SIP & RTP packets can be a big issue.

Thanks for the info,

Figured as much.

Scrapped my endian for good ol' IPCop. May add the endian fearures I liked via extensions.

Want to use my home setup to proxy my SIP connections from any of my VoIP clients; thinking Gizmo5/GizmoCall, and break-out calls to landlanes to be billed (& listed) to my VFX account.

Maybe make free SIP calls to my home point

Seems feasable/standard practice from what you're decribing

What kind of scale are you talking about here?

Small-fry. Very small fry. 1 SIP account; 2 @ most

I'm trying to learn & get my head around the SIP protocol & get more familiar with VoIP tech.

I work for a messaging company ( conversions between mail, fax, sms, voice, etc, etc), and looking @ ways of integrating IP telephony.

As XNet/VFX already provide me with a SIP account, but do not support my "hacking" mucking about (term VERY loosely used here), this would be the place to get my info.

At this stage it's all really just proof-of-concept, as I'l propably break stuf, and then break it some more.

I'll read up on maverick's posts in the upcoming weeks, if only to just to avoid all those "RTFM" flames I'm bound to get.
Done fair bit of wikipedia reading already, so I *should* be able to follow most conversations
