Viewing Settings and Network Parameters on IP Phones
Use the Configuration (Debug) Menu on IP Phones to view the settings and network parameters
on an IP Phone. The procedures to access the configuration menu on Single Mode IP Phones
and Dual Mode IP Phones are different. You can identify a Dual Mode phone by checking the
label at the back of the phone. The label will specify the phone as “Dual”.
CAUTION: If you change the Amphenol connector on an ASU it will affect all
users who are connected to that ASU.
Note: The default setting from the factory is MiNet mode. The procedures described
here are based on MiNet mode. The phone menus may vary in SIP mode.
