Anyone have 2talk running on a Linksys WRTP54G? Used the following generic SIP settings from the 2talk website, but it doesn't want to register.

IP Address: Use DHCP
Sip Server: 2talk.co.nz
Outbound Proxy/Proxy Server: 2talk.co.nz
SIP user ID: <2talk phone number>
Authenticate ID: <2talk phone number>
Authenticate Password: <2talk password>
Voice Codecs available: iLBC,G729,GSM,PCMA (alaw),PCMU (ulaw)
Video Codecs available: H.263,H.264
Voicemail user ID: *55
STUN Server: should not be required ('stun.2talk.co.nz' if needed)

Any advice?

I didn't look around their website enough. The "installation guides" section had info on a Linksys SPA-2102 ATA router that I copied the settings from. I think the main prob was that I had entered my 2talk number in the AuthID field (as per the generic instructions), but not in the UserID field. Seems it needs this number in the UserID. Anyhoo, works now, but my router is defective and produces a lot of noise in the voice ports. Not a problem with my PAP2T adapter, but that's tied up with Xnet VFX. Anyone have an idea of what can go wrong with these routers to make the voice calls noisy? Would have to think it's something simple, as the router functions are fine and voice does work, in a fashion...

I have the WAG54GP2 (similar but not the same), which also started to develop static on the VOIP ports, which I could not resolve. In the end I had to return the device for replacement. The newer router was working fine the last time I tried the VOIP ports. You could try a firmware upgrade to see if that clears it, but - from my experience - if its reasonably new, call Linksys and report it as faulty and get a replacement.

try putting your 2talk number of the open 2nd line of the PAP2T device and see if the issue is still there, will help you nail it down to a hardware or service problem

Haven't had the inclination to put the 2talk service on the PAP2T yet, but the WRTP54g router's voice ports were noisy when I had my XNet VFX service on it. Cleared right up when I transfered the VFX to the PAP2T. Signed up for the 2talk service so I could muck with the setting to try to resolve the problem, but anecdotal evidence seems to indicate there is a hardware problem. I am reasonably handy with a soldering iron if anyone has an idea of how one would begin diagnosing this problem.

I think you will find that all the internal circuitry is surface-mounted components. You need a vacuum desoldering station to remove the components and then some sort of hot-air reflow gun in order to resolder them again. Unless you have excellent eyesight and the super-steady hands of a surgeon, it would be a daunting task, even if you knew which components were faulty.

Why not return the WRTP54G to your supplier for repair under warranty?

Router was purchased used on ebay; return is not an option, and neither is surrender. For all I know the problem could be an easily-replacable $.30 capacitor. Hoped some smart cookie out there might have an idea and be willing to share it.

Well, a good start would be to get hold of a circuit diagram and then you could see which components are in the Analogue part of the device and hence could introduce noise into the phone circuits. As you say, it could be a faulty cap. It could also be a noisy resistor or noisy voltage reference diode. Or one of the analogue amplifier chips could be causing the problem.

Without a circuit diagram you are really clutching at straws so have a hunt on the web and see what you can find. During various searches for documentation on Linksys devices, I found Administrator Manuals in obscure places on the web, but don't recall ever seeing a circuit diagram. Most of the Asian manufacturers will not release such diagrams as they regard them as their Intellectual Property. If you want something repaired, they will point you to the nearest authorised service agent.

However, with a company as big as Linksys, maybe they do have circuit diagrams available. I remember buying genuine copies of the IBM Technical Reference Manuals for the PC/XT and PC/AT. In the back pages of both of those manuals was a full circuit diagram of the motherboard, extending over many, many pages. Unfortunately I think those days are gone, never to return

P.S. One thing you can do in the absence of a circuit diagram is to poke around the board with a long plastic nozzle on the end of a can of "Freeze". Try squirting various components with the nozzle one at a time and listen to the noise in your phone handset. If the noise reduces drastically when you squirt a particular component -- maybe, just maybe you have found the faulty one. Then you just have to figure out what type it is and where to buy a replacement.

The rationale here being that when an electronic device is colder, it produces less thermal noise, hence the reason why they used to run microwave receiver front-ends refrigerated in coolant to keep the noise level down. This was before the availability of modern "LNB" type circuitry.

I hope that helps.

Cheers,
Grant.
