I had an interesting experience with the zoom.  Their SIP
implementation doesnt' expect to see SIP traffic on the internal lan,
and running * on the internal lan would lock up the modem.  Completely
repeatable, just start up * and the modem locks up hard, lights go
solid, etc..

Tech support didn't seem to think that this was an issue, and told me
that they only supported voip using their own service.  Tried telling
them that regardless of what they support, if traffic on the lan locks
up the modem, it's a bug.  I finally just returned the unit and got my
money back.
