Dear Forum,

Please can anyone offer any insight, or prior experience on this matter.

I have recently transferred my VFX fusion service from a provisioned voice service, to an asterisk server. I have installed and setup Asterisk, with internal extensions. I have registered 2 trunks successfully, and can make, recieve and route calls between Asterisk, internal softphones, a SPA922, and the big bad world.

VFX have kindly sent down a blank config and I am able to configure the settings on the 2 voice lines myself. When I was testing the wag54gp2, i was able to register either of the lines to asterisk, using an the internal proxy address of my Asterisk box, and successfully connect an analogue phone and fax to my internal VOIP network. It seems I am still able to do this when I am not using the router as an ADSL modem.

HOWEVER, when I am using the router as an ADSL modem, I get 'failed' registrations every time. As if it is perhaps looking for the internal ip address (192.168.10.65) on the WAN, not the LAN.

Is there a simple config setting I am missing? I've tried disabling NAT, editing the voice DNS address etc etc. Is there some way of making the wag54gp2's voice hardware default to internal IP addess? is it a firewall issue blocking the asterisk from talking back to the router? Has anyone else successfully done what I'm trying to do.

I have found this forum http://forums.whirlpool.net.au/forum-replies-archive.cfm/510162.html, and some unresolved threads on Geekzone.

I am considering returning the router already, as it won't allow me to assign IP addresses (see http://www.geekzone.co.nz/forums.asp?forumid=65&topicid=24789). But if I can successfully use the phone ports for my internal network, i may keep it.

Or am I just wasting my time with this dodgy hardware, and should I swap it for a solid netgear adsl/wireless/router and get an individual analogue-voip converter for my fax machine.

(on this last point, can anyone recommend a solid VOIP-ANALOGUE converter which with T38 codec support?)

Thanks
Nick

I spent countless hours trying to get this to work and came to simialr conculsions to you, that it will only register on the WAN and it won't look at the LAN. Have a look here for a thread I started http://www.geekzone.co.nz/forums.asp?ForumId=43&TopicId=20793

That would be right. The WAG will always try to register via the WAN port.

What you need is a normal ADSL router without VoIP ports and then a separate ATA or Router with VoIP.

As Filterer has already said, you are wasting your time on the WAG.

Because you want T38 support, I would recommend the Linksys WRP400 which provides 2 VoIP ports with T38 support. You can plug its WAN port into a LAN port on whatever ADSL router you end up with, and then the WRP400 will register with your Asterisk box

Ubergeek and Filterer, thanks for your posts.

Actually, i did, much to my suprise, resolve the issue of the phone ports not registering with my asterisk box (this may be of use to you, Filterer). Basically, if you go into the WAG controlpanel, under 'Settings' -> 'Voice Connection', there is a drop down box, which corresponds with any PPOE settings in the main adsl screen. The dropdown was set to 1, which means that voice was trying to use my ADSL connection to glean it's IP addresses and connections. I simply changed this to 8 (or any other, unused connection), and now both voice ports are registering just fine with Asterisk. So at least I have use the phone ports.

In the advanced voice settings of the WAG54GP2, it appears to allow T38 (a drop down called 'enable T38, yes/no'), although the default codec is set to g711u. Although I am successfully routing calls to my fax number, through the the fax machine, I have not yet succesfully transmitted or recieved a fax. I've enabled T38 passthrough in Asterisk, but I'm fairly sure there's a little more work to be done before I give up the ghost on this one, and buy a telecom line just for the fax (b**ger me, why is fax even still a standard??)

I'm also still a little miffed about the non-functioning DHCP assignment in the WAG54GP2, and may yet be returning it. I hear VFX are trialling a new bit of hardware, to bring to market v soon. Would have been nice to know this before I went and forked a couple hundred on a somewhat lame bit of hardware..

Thanks for the info! I'll have to have another look at it

Let me know how you get on.

I am now recieving calls on the phone ports, and making internal calls. Outgoing is unusual - it works fine calling my other VFX line (and, i think, anyone else on the VFX network), but for mobiles or landlines, it dials, and the other party rings but I don't hear anything.

I think it may be a conflict between asterisk outbound dialing rules, and the preconfigured dialing rules in the WAG54GP2.

I am also yet to recieve or send a fax successfully.

I would be very interested to know what the exact configuration settings VFX send down when they provision the WAG themselves, so I can be sure to use the optimum codecs and settings at all points (WAG -> Asterisk -> VFX). Is there any info on setting up one of the ATAs or WAG router/phoneports manually? I know VFX prefer to provision, to remove the hassle of dealing with exactly this sort of thing.
