I've been toying with the idea of combining my PSTN & VOIP lines
through one ATA, but I seem to remember reading that some users had low
volume on PSTN calls on the SPA3000. Can anyone who has used the
SPA3102 tell me whether it suffers from this problem or not?

Changing the FXS impedance to the UK spec of "370+620||310nF" and
altering the VoIP-PSTN gateway/PSTN-VoIP gateway gain levels should be
able to solve that. It's a balancing act between getting the volume
high enough without introducing echo on some or all calls. The same
applies to most VoIP equipment connected to analogue lines although in
some cases with the more expensive VoIP cards you get built-in echo
cancellers.

So if I understand you correctly this will apply equally to the 3000
and the 3102? Since I already have a router with QOS the built-in
router in the 3102 is superfluous to my requirements. Will I then be
just as well off technically (and better off financially) in buying a
3000?

Yes that applies to both the 3000 and the 3102. You might as well just
buy a 3102 even if you don't need the router functionality as they
should be the same price.

Thanks Paul. Please excuse my ignorance, but how do I disable the
router? Do I just connect the LAN port to my switch (as my current SPA
1001 is) and ignore the WAN port completely?
Alternatively if I replace my existing router will the connections be:
ADSL filter ->SPA 3102 ->switch ->LAN ?
Can't seem to get my head round this one, and I haven't found a simple
schematic for it anywhere. A confusing factor (to me anyway) is that
the Linksys documentation uses the terms "Ethernet port" and "Internet
port", which I presume equate to LAN and WAN ports respectively.

More or less. I can't remember if the WAN port is plugged into your
router's LAN port & the SPA's LAN port is ignored......or the other way
around.

No, it doesn't have an ADSL modem in, so it would have to be
ADSL filter -> ADSL Modem with ethernet out ->SPA 3102 ->switch ->LAN

Yes plug the WAN/Internet port into your existing router and just ignore
the LAN/Ethernet port on the SPA-3102. No need to actually disable
anything, just ignore it.
The only problem is you'll have to temporarily plug a PC into the
LAN/Ethernet port to be able to access the web interface to configure
the SPA-3102 as you can't access it using the WAN port by default. Once
you are in there is a setting to enable configuration using the WAN port.
I think I'm almost ready to order, but a thought has just struck me.
Can you only make outgoing calls through VoIP or can you specify PSTN
as one of your outgoing providers?
I have a specific requirement for a particular destination to be called
via my PSTN line (probably through the Orchid dialler which will sit
between the 3102 and the line). If it needs an access code, I can
specify this in the short code dialling of the telephone set.

You can, yes. Even to the point of saying only a particular number
should be dialled over the PSTN (or VoIP)

If you're going to use a proviedr such as voip.co.uk, you could
actually choose to present your PSTN number on your VoIP line.

The AVM Fritz!Box range can do this; either a prefix (for example 0870) or
a particular number can be made to route via any specified account or the
PSTN line.

Yes, send the number to gateway 0 (gw0) just add it to your dila plan

Thanks for your help (and to everyone else - again!)

Well, I took the plunge and bought one. Having got lots of good advice
from you good folks I was up and running quickly. So far so good; I
have all my providers set up and working and the PSTN line rings.
However, I get no CLI (or CID as Linksys call it) on incoming PSTN
calls. I have googled a bit and found that some people have had a
similar problem, while for others it seems to be OK.
That leads me to believe that it must be doable, so does anybody have
any idea of the settings that I need to change to achieve this? (I have
already changed the Caller ID Method under the Regional Tab
(Miscellaneous) to "ETSI FSK With PR(UK)" and the VOIP CID works fine).

More bad netiquette in replying to my own posts, but I managed to solve
the CLI problem. All I had to do was to upgrade to version 3.2.10,
available from the Linksys site, and it worked straight away. I thought
I'd post this follow-up in case anyone else in the UK facing the same
problem googles for it.
