DECT Handset features
The user of a DECT
Handset subscribed on SIP DECT can perform the following actions:
• Make calls to DNs except restricted or blocked DNs.
• Receive and answer calls from the Call Server. If CPND is available, the name of the
caller and DN appear on the Handset display. The position and appearance of the name
DN on the display depend on the firmware installed on the Handset. You must configure
the required CLS in the UEXT block (CNIA/CNDA/DNDA) and username in LD 95. SIP
DECT also supports CLID restrictions (for example, CLBA, NAMD, DDGD). SIP DECT
Handsets support display update during established calls; this allows SIP DECT on SIP
Line to show a new display name for the connected party. During transfers (both Blind
and Consultative), this provides the new party’s name on the DECT Handset after the
transfer is complete. The display name is taken from the CPND block created for SIPL
UEXT.
Note:
During a transfer
, only the display name updates, not the connected number.
• Place the active call on hold by pressing the R key on the Handset. Return to the held
call by pressing the R key. If a call is on hold, another call can be made from the Handset.
After the second call is established, the user can switch between the two calls with the R
key.
