Possibly, though you'd need more help on the dial plan than I can
offer, without something in between, like Asterisk.

These are some of the things I use my 3 for:

an analogue phone to a Voip service.
an analogue line to the same box/phone
an analogue line to a Asterisk PBX
an analogue phone to a pbx
a remote analogue line (I can make and receive calls on my Mum's
landline)
a remote analogue phone connected to my PBX
a GSM gateway connected to my PBX

So, I can, using Asterisk in between, dial out on my fixed line, or my
Mum's, from any of my IP phones and, of course, answer the landlines on
any phone.

Look at http://www.provu.co.uk/support.html in the Linksys section for
some interesting articles.

Note the SPA3000 was superceded with the SPA3102.
