Allo,

I got VFX provisioned on my line cause I could and it's free... YAY! Umm, I know nothing about Asterisk / VoIP :P

Has anyone got any cheat sheets, links to resources, etc... what I am looking for is a basic "What you need for Asterisk to work with your provider cheat sheet..." and a "How to use your softphone..." type guides. I don't have an ATA yet... just testing the water before I jump ship to fusion (and cause I like to try stuff like this).

I got it installed and running, when I do a "sip show peers" I get this...

*CLI> sip show peers
Name/username              Host            Dyn Nat ACL Port     Status
Walter/Walter              192.168.1.100    D          10086    Unmonitored
VFX/<AUTHHERE>     58.28.20.150         N      5060     Unmonitored
2 sip peers [Monitored: 0 online, 0 offline Unmonitored: 2 online, 0 offline]

Walter is the softphone running on my pc... does this mean its registered? What now?

Check Tony Hughes blog, some old posts have a complete Asterisk configuration for VFX IIRC.

Here is a good start Point

which leads into this great little guide from Tony Hughes http://www.geekzone.co.nz/tonyhughes/4186

Thanks guys, wow, I didn't think I would get the Ops Manager @ Xnet and the Geekzone admin both replying to my post... <g>

I did check out both Maverick's Asterisk post and also Tony's blog. I have got the settings in Maverick's post configured and really just need a basic guide about some of the fundamentals of Asterisk and most (if not all) of Tony's posts refer to Trixbox and hence web interface configuration which isn't relevant. I am not interested in using something that basically hides all the configuration behind a shiney web interface (yea yea I know stupid of me but hey, you don't learn anything that way).

I want to know stuff like

What's a dial plan, where you need to use it
What's a trunk, how you configure it
etc, etc

I have done some quick searches on the net, but not found anything that's been really helpful and instead of wading through a "Dummies guide to Asterisk" just to get a basic understanding of the components I was hoping some of the knowledgable forum members might have just such a resource book marked.

No worries, will keep searching.

Have a read of this - it's a very comprehensive book on how to set up asterisk, what all the terminology means etc. It's also very easy to understand, and freely available - kudos to O'Reilly for this.

Thanks Bletch, just what I was after, will post some confs and links once I get this all working :)

Have also found chris021's blog post on the basic sip.conf for VFX which got me registered.

Will check with Xnet to see if I have something wrong in my setup to stop registration.

Glad you found it useful. I recommend you remove your phone number from that last post though.

Can you paste your sip.conf here?

Thanks man. Just spoke with XNet and they can see that I am registered even though the Asterisk console is still spitting out :

Other than having no incoming context for your VFX trunk, that config looks fine. What's your firewall setup like?

Righto... so would add

context=incoming

to the sip.conf section [VFX]?

I have a Cisco 877, haven't allowed anything in specifically for VFX... do I need to open a port and nat it to the VFX box?

JDNZ: Righto... so would add context=incoming to the sip.conf section [VFX]?

Yes, assuming that you wish to receive incoming calls in that context.

I have a Cisco 877, haven't allowed anything in specifically for VFX... do I need to open a port and nat it to the VFX box?

You shouldn't need to add extra NAT rules. The reason I asked is because your exact symptoms can be caused by a firewall that's missing an ESTABLISHED,RELATED pass rule - this is a mistake commonly made by new iptables users.

Cool, so no need for anything specifically setup on the router then as I don't use a local firewall on NIX-1.

Guess I will keep playing around with it see if I can sort it out. Thanks for your help, at least I know I am on the right track.

Cheers,
Brad

umm, yup its official, I should pack up all my computer equipment, take it back to where I bought it and tell em I am too stupid to own a computer.

It was the firewall on the router... when I finally got around to checking it it was blocking the packets from as.wxcnz.net...

Haha, glad to hear you have it sorted :D

Don't feel too bad, we've all made that kind of mistake at least once.... firewalling yourself out of a remote server is far more embarassing - trust me on that ;-)
