Browser
The Polycom VVX 1500 D phone supports a full browser. This can be launched
by pressing the App key or it can be accessed through the Menu key by
selecting Applications.
Two instances of the Browser may run concurrently:
• An instance with standard interactive user interface
• An instance that does not support user input, but appears in a window on
the idle display
Configuration changes can be performed centrally at the provisioning server
or locally. For detailed information on configuration file settings, refer to
on page A-5 .
H.323 Protocol
Telephony signaling support via the H.323 family of protocols enabling direct
communication with H.323 endpoints, gatekeepers, call and media servers,
and signaling gateways is supported on the Polycom VVX 1500 D phone.
SIP and H.323 signaling can be supported at the same time, including bridging
both types of calls during multi-party conference calls. Automatic detection of
the correct or optimal signaling protocol is available when dialing from the
contact or corporate directories. While SIP supports server redundancy and
several transport options, only a single configured H.323 gatekeeper address
per phone is supported. H.323 gatekeepers are optional, but if available, they
must be used. If a gatekeeper is not configured or unavailable, calls can still be
made if so configured.
Support of the SIP protocol for telephony signaling can be disabled on the
Polycom VVX 1500 D such that all calls would be routed via the H.323
protocol.
Video calls are supported to the following Polycom endpoints/bridges/call
servers (or gatekeepers)/media servers:
