Neither.  It's a voice over layer 2 phone.  It does indeed go over ethernet,
but not at the IP level.

But, as I said, it's not a VoIP phone.  It's VoL2, which might have
problems.

Jeremy, you seem to think that the only type of ethernet phone it could
be is VoIP.  That's obviously not the case.  Because it's layer 2, I
can easily believe that some sort of interference affected the phone's
connection.

Have we sent the "Don't shoot, we're pathetic" transmission yet?
