[Asterisk-Users] SIP phones with dual ethernet.

The polycom phones (ip 500) have a simple switch built in.  I say simple
because we had an issue were a network device was generating large
amounts of traffic to nonexistent mac addresses and the computer behind
the phone would not receive some packets.  Probably not an issue though
as once we got the network device to behave correctly, we haven't had a
single problem.

Hi list.

Some of the available phones out thera have dual ethernet ports.
As we all know using SIP behind NAT could be frustrating.

Some vendors sells phones with dual ethernet ports. Are these just
incorporating a hub/switch functionality? The reason for my question is
that the normal case for a DSL customer is the possibilty to use one MAC
adress from their service.  With MAC cloning or other functionality this
could  work out to be a solution.

Does anyone of you out there have any experiences in this matter?
