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.  
10.3.2.1  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.
10.3.2.2  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 the DECT phones should receive calls on the PSTN line. (P-
2302HWUDL-P1 model only) 
When you assign a specific SIP account to be used with the DECT phone for outgoing or 
incoming calls, all of the DECT phones registered with the ZyXEL Device use this SIP 
account for making or receiving calls. 
10.3.2.3  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 
models the flash key is the “R” key.
