You turning down the audio gain, makes BT turning it up ?
isn't there a call-smart setting possible in your situation ?

Yes, since I mostly only use the VOIP account.

In fact, the echo is much worse on calls to the analog BT line, but I
only give out the VOIP number.

I've got a couple of SPA3000s. Both are acting as PSTN trunks on my PBX
and also as regular ATAs.

I get the old echo on PSTN calls but not on VoIP calls.

Frustratingly so.

You asked in your original post about the Fritzbox.
I have one and I also have an SPA-3000.
I would say that the Fritzbox performs well and is much easier to get
up and running, for the average person, than the SPA-3000.
However, for me, I would have the SPA-3000 every time.
My prime reason for saying this is the ability to customise the
dialling experience via the dial plan. In its effort to be simple the
Fritzbox loses out in this area. I have hardly used my Fritzbox 7140
but I am considering selling it just for this reason - so any offers
by email greatfully received.
Personally, I have experienced little trouble with echo on either my
SPA-3000 or the two SPA-3102 that I have set up for others.
It is important to get the line impedance set correctly - then I just
tweak the gain, as appropriate, and switch on the echo cancelling
options.

On a separate topic, not wishing to hijack the thread...
I remotely control one of the SPA-3102 so that I can sort out any
problems from home. I have found that it is impossible to get the web
'Voice' control interface to come up correctly on a Windows XP Pro
platform using Firefox, Opera or MSIE 7.
The problem I get is that all the tab contents displayed under each
other, in one long list, and then the egg timer just hangs as if
waiting for more data. I have tried emptying the RAM and disk cache to
no avail. I am aware that this web interface uses javascript so there
may be some problem there though I don't think that is the problem.
In Ubuntu Linux it will display OK most of the time but sometimes the
page needs to be loaded again for a correct display. So, I am tied to
booting up in Ubuntu if I want to access the SPA-3102 remotely.
Any ideas on this one?

So i guess you already overcome the problem of accessing the 3102
webinterface, i thought i had setup it correctly to do so, but i only
had access when the pc was straight plugged into the 3102, not both via
LAN :( what's the secret ?

Follow the instructions here, if I've understood your question
correctly.

I have similar problems with an SPA1001 & SPA3000; the advanced log-in
yields one long vertical page covering all the tabs with bits missing.

I overcame this by using a VPN at one site and Remote Desktop at
another.

This has the sound of an MTU problem to me. I would monitor your
network traffic with WireShark and watch what happens when it stalls.
And/or, try temporarily reducing your client's MTU to something like
512. That's not a fix, but if it temporarily solves the problem, you
can then examine the network to try to see what's causing it.

Cheers,

- Martin.

Well, at least it's not just my one that does that ;-)

Now that I've found the "more echo cancellation" tickbox in the v3.x
firmware, I will wait and see whether that solves or reduces the
problem. I did have one PSTN call earlier, and it seemed OK, but then
the thing always seems a bit intermittent.

Cheers,
