Deployment Guide for the Polycom VVX 1500 D Phone

For more information on all of the configuration parameters that you can change, refer to the latest SIP Administrator’s Guide at http://www.polycom.com/support/video/business_media_phones/vvx15 00d.html .

Time and Date Display

The phone maintains a local clock and calendar. Time and date can be displayed in certain operating modes such as when the phone is idle and during a call. The clock and calendar must be synchronized to a remote Simple Network Time Protocol (SNTP) timeserver. The time and date displayed on the phone will flash continuously to indicate that they are not accurate until a successful SNTP response is received. The time and date display can use one of several different formats and can be turned off.

For instructions on turning off the time and date display, refer to Polycom VVX 1500 D Display on page 3-2.

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 Microbrowser <mb/> on page A-6.

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.
