IP Video Doorphone
The IP Video Doorphone (IP3NE-IPCDH) can be connected to SV9100 system
through a PoE Data Switch and is normally used to monitor an entrance door. When
pressed, the Doorphone sends a chime tone to all extensions programmed to receive
the chime. To answer, the called extension user just lifts the handset. This lets the
extension user talk to the visitor at the Doorphone location. In addition, a user can
view the outside image using the DR-viewer application (installed on a PC in the
same network) or the image can be viewed using a Polycom IP VVX 1500 terminal.
Each Doorphone has a Normally Opened and a Normal Closed relay contact that
can be used to connect to the electric door strike. These contacts are used to
remotely control the entrance door. After answering the chimes, a Multiline Terminal
user can press the Recall key and activate the Doorphone contacts. This in turn
releases the electric strike on the entrance door.

SIP Trunk E.164 CLIP Enhancement
With the SIP Trunk E.164 CLIP Enhancement enabled, when an incoming
SIP call from an external ITSP is presented at the system with a + in the
From header field as the international access code, it is recognized and
displayed as an international call at the terminal display and also logged
in the terminals incoming caller history, allowing any outbound calls made
from a multiline terminals caller history possible using this numbering
scheme.
This presentation can be a requirement of certain SIP ITSPs (Internet
Telephony Service Providers) so it is necessary the PBX can handle
these calls and modify any SIP messages to the correct format
accordingly.
