Each DAP communicates with the subscribed DECT handsets in the
coverage area, and each DAP interacts with the CS 1000 and with other
configured DAPs in the company network.
You can run SIP DECT on the following configurations:
•
Communication Server 1000M or Communication 1000E
•
Signaling Server running SIP Gateway (SIPN only) or Signalling Server
running SIP Line Gateway
Use the SIP Redirect Server or SIP Proxy Server to perform the
appropriate NRS configuration for SIP DECT (SIPN connection type):
•
You can run SIP Redirect Server on Internet Server Platform (ISP)
1100s, Call Processor Pentium Mobile (CP PM) signaling servers,
or on IBM or HP Commercial-off-the-shelf (COTS) servers under
VxWorks.
•
You can run SIP Proxy Server on IBM or HP COTS servers under
Linux. You can run SIP Redirect Server on the same Signaling Server
as SIP Gateway dedicated to SIP DECT.
•
You can run SIP Redirect Server on a stand-alone Signaling Server.
If you install SIP Proxy Server you must use a stand-alone COTS server.
You cannot run SIP Gateway on the same server as the SIP Proxy Server.

Universal extension support

DECT handsets subscribed on DAPs are external to CS 1000. The CS
1000 does not control the state of DECT handsets. Therefore, the CS
1000
•
cannot detect individual key presses on DECT handsets
•
cannot control cadences on DECT handsets
•
cannot detect if a DECT handset is switched off and on
•
cannot control the handset display content
A DECT handset subscribed on a DAP cannot use the same range of
features available to analog, digital, or UNIStim IP phones on the CS 1000.
The Universal Extension (UEXT) feature on the Call Server provides
Configuration and status information for subscribed DECT handsets.
