Yes. It looks like a SIP device to Asterisk. (well 2 SIP devices) It's
the HT-503 model.

Downside is that it's a stand-alone device and not USB, so needs Ethernet
and PSU plumbing. Actually, that's not really a downside in the grand
scheme of things, however...

Obviously you need a POTS phone provider that passes through the caller-id
number.

If I phone home from my mobile, I see:

    -- Executing [1234@fromSIP-pstn:1] NoOp("SIP/pstn-000001f7", "Incoming SIP
call from ""  @ pstn calling 1234") in new stack
