I bought a SPA-3000 from Voipsupply and a SPA-2100 from Telephonyware,
and in both cases they came with RJ-11 connectors and cables. UK or
other types of adapters for the power supply are available at a small
surcharge, but I find it cheaper to buy them (and the RJ-11 adapters as
well) in the street.
Anyway, for the SPA-3000 a cable adapter may not be required at all,
because typically those devices are inserted between phone and line,
and many phones have an RJ-11 socket on their body: so one can just
unplug from the phone the cable coming from the line and plug it into
the "PSTN" port of the SPA-3000, and use the RJ-11-to-RJ-11 cable that
comes with the SPA-3000 to connect the latter and the phone.
