A friend who has no router ,and only a laptop, wants to use voip.
I've never tested the SPA-3102 as a router. Has anyone tested it in
the UK (PPoA) and found it to work reliably? This would be operating
with a VM supplied cable router.

PPPoA has nothing to do with cable, so forget about it. It should just work.

I wondered about that. Thanks for pointing that out.

Why use the 3102 as a router if the friend already has one supplied by
VM? Just stick it on an unused port.
However do beware of one problem with VOIP - if the router is using NAT
then you will almost certainly need multiple port fowarding. I had a
Belkin wireless router which would only allow one port to be forwarded
to any one given IP address downstream and I just could not get VOIP to
work. Switched it with a Netgear and all worked/works perfectly.

You are correct. I see the mistake I made. Yes, he has no router just
a cable modem.
Presumably though, if this was an ADSL situation, then there would be
problems using it as a router unless, possibly, on AOL, where,
certainly at one time, if not now, I do believe they used PPoE.
I have set up an SPA-3102 on VOIP, not my own, but I never bothered
with the router part. In the case of someone without a router, who
only wants to run one computer, it is an ideal product to operate with
a cable modem but not, generally, I would assume with the vast
majority of UK ADSL ISPs who use PPoA. Why Linksys don't make it
compatible with PPoA I can't imagine. It seems to be typical US
parochialism.

Sorry to argue Jono, but I'm only speaking from experience.
I signed up with Sipgate (no credit) and downloaded the free
ready-customised XLite softfone. It would work with incoming calls but
no way outgoing (to their free test number or another Sipgate user.)
Interminttently I spent about a month trying to get it to go with no
joy. Then I bought the SPA2000 - and had <exactly> the same problems. It
wouldn't work with voip.co.uk either, as wouldn't a non-customised
XLite. Even Sipgate and voip helplines were unable to come up with a
solution.
I picked up a Netgear at the right price and had the same problem. I
then set the router to fixed internal addresses (still using DHCP from
the cable modem,) put on the port forwarding, and behold it worked and
still does.
my configuration to the one in question is almost identical
VM - cable modem - linksys 2102 voip/router - single pc
Line 1: Voxalot - 2 VSP - Voipcheapcom for outgoing and Orbtalk for
incoming
Line 2: Voxalot only - so I can natter with friends & family who also
have a Voxalot account, and leave Line 1 free for business calls!

The Linksys SPA-3102 doesn't have an ATM interface, so PPPoA would be of no
use whatsoever.

I guess that's why the SPA3102 worked for me instantly, because i
connected the SPA on a LAN port of my router, only did set the LINE1
voice menu, en left DHCP on router still running, guess that QoS is not
running, so this would be a other case, if i had a ADSL modem only

SPA3102....with DHCP switch on, on SPA and swited off on router ?
