Please keep us (me) updated on what the call quality, echo, cut-outs are
like.

No echo noticeable. So far, unable to tell any difference between fixed
and voip calls. Audio quality is fine, however, like most modern DECT
phone there is no side tone which takes some getting used to. Managed to
register my 2 existing handsets with the base station without any problems.

Got mine from DST (UK) via Amazon, not the cheapest, but they had stock
and I had an Amazon voucher.
Phone has now arrived and I am pleased with it. I do like the ability to
download/edit/upload the phone directory. Much easier to type on a keyboard.

I've used 2600's in the past with good results. However they seem to have
bugs with NAT handling. Not sure if I've found a good replacement for
them yet though - currently looking at Zyxels...

The QoS (traffic shaping) will help with uploads, but not do much for
downloads.

You could put a 2nd router (one with 2 ethernet interfaces) after the
2wire router, but it them becomes messy..

I'm not a fan of Wi-Fi phones, but saying that, I have a nokia E90 and
it's been working very well - however my desk is only a few metres away
from the base station and the Wi-Fi network is very lightly loaded.

The coverage from the Siemens units has been very good - especially if
you mount their base stations on a suitable wall.
