For the PHONE 1 and PHONE 2 ports, an extension number is composed of a group number
and a sub number. If group number is not enabled, the extension number is simply the sub
number. You can assign a group number to the two phone ports. When you dial a group
number, all phones belonging to that group ring.
The MSNs you configure are used by the ISDN phone(s) connected to the ISDN port. You
must also configure your ISDN phone(s) to use these MSNs. You can use the MSN to call an
ISDN phone from another phone connected to the ZyXEL Device.
"
If an ISDN phone already has a MSN configured (for making and receiving
ISDN calls), do not change it; otherwise ISDN calls may not work.
Use the Ext. Table screen to configure the extension number of the PHONE 1 and PHONE 2
ports, and ISDN phones connected to the ISDN PHONE port on the ZyXEL Device. To
access this screen, click VoIP > Phone > Ext. Table .
"
Make sure each Extension Number you configure in the Ext. Table screen is
unique.
