Is there stand-alone IP desk phone which will do all of the following:

Incoming calls via a single PSTN line
Incoming calls via 3 SIP accounts (different providers)
Outgoing calls via 2 or 3 other SIP providers
Allow a minimum of 1 call for each incoming number/account to be in
use, held, or visibly ‘ringing’ at any time.

Alternatively is anyone aware of a 3 or 4 line POTS phone available in
the UK?

I'm currently achieving this with a Fritzbox and a PBX, which seems a
bit of overkill to feed calls to one user.

There are some DECT phones which can do more or less what you want. The
Siemens range can take 6 (I think) SIP accounts and one PSTN port. Not
quite a desk phone, but ...

The other alternative might be a PBX with a single analogue port - one
that can handle many SIP accounts - Build your own using pbx ina flash,
trixbox, etc. out of a spare PC.

What are you actually trying to achieve?
