If you wish to have VoIP stations outside your network that
connect back to IC and place calls without using VPN , there are
several things you will need to configure. Primarily you cannot use
the Mediant 800 for your primary Data router. You will instead need
a Secondary router that will handle the HTTP(S) traffic from the
WAN Phones. See the diagram below:
For IC to function properly with a
WAN Phone & Switchover, all
HTTP(S) traffic will need to be
routed through a separate device.
Ports 8088 and 8089 will need to be
sent through your firewall using
port forwarding, static NATs, or a
separate method of your choosing.
The end result being that a WAN
phone can contact either server for
its configuration files, depending on
which server is Active , and that the
HTTP(S) traffic does not go
through the M800.
The reason for this is due to a
limitation of the Mediant 800. If a
DNS record returns more than one
IP, the first IP returned is the only
IP Address used.
One other thing to note is that this
configuration disallows provisioning
managed phones by end users,
and rebooting the phones remotely.
All phones will need their MAC
addresses entered at the time of
creation.
