Question
How do you connect and use the Philips 4331 phone to a Magic Jack system?

Answer
The simple answer is no.

The complex answer is yes,
but you would need a bunch of
other components. If it would then still
be worth your while or not is another
thing.

You could use Asterisk to act as a
phone server. Then connect your VoIP
phone to it.

The majic jack can then be cracked and the
registration credentials entered into the
Asterisk server instead. I dont think you
could put these credentials directly in you
phone, as the last time I checked magic jack
was reading the client type field out of the
SIP message and it had to match their
string exactly to fake it. Asterisk allows you
to change this field on the fly to anything
you want.  

You could then dial via the Asterisk server
using your majic jack credentials to
make PSTN calls.

Its work... Why not just buy a cheap $10
analog phone and stick it in the majic jack?
