The following table summarizes the types and number of calls you can make with your DECT
phones via the ZyXEL Device.
The ZyXEL Device does not control how your DECT phone distinguishes between internal
and external calls. Typically, a DECT phone has a button labeled int to indicate an internal
call. Consult your DECT phone documentation for differences in making internal and external
calls.
12.10.2.1 DECT Phones - Internal Calls
To make internal calls, you need to know the phone numbers of the other DECT phones
registered with the ZyXEL Device. The ZyXEL Device assigns numbers based on the order
that the DECT phones registered with the ZyXEL Device’s DECT base station. The first
DECT phone that registered with the ZyXEL Device’s DECT base station receives the number
1, the second the number 2, and so on up to the last registered DECT phone.
Refer to your DECT phone documentation for specific details regarding your phone’s calling
functions.
12.10.2.2 DECT Phones - External Calls
To make external calls, follow the same procedure as with the analog phone connected to the
ZyXEL Device. You must also:
• Specify the SIP accounts for incoming and outgoing VoIP calls.
• Specify whether each DECT phone should receive calls on the PSTN line.
12.10.2.3 DECT Phones - Supplementary Services
There are two ways to perform supplementary phone services like call waiting, conference
calling and so on.
• Via the handset - refer to your DECT phone documentation.
• Via the flash key function - refer to Section 12.12.1 on page 209. On most DECT phone
models the flash key is the “R” key.
12.10.3 DECT Phone Screen
Use this screen to configure your DECT base station settings. To access this screen, click VoIP
> Phone > DECT Phone.
