H.323 Protocol

VVX 1500 phones and video-enabled VVX 500/501 and 600/601 phones support telephony signaling via the H.323 protocols.

H.323 protocol enables direct communication with H.323 endpoints, gatekeepers, call servers, media servers, and signaling gateways.

Note: You need a license key to activate H.323 video on your VVX 1500 phone; the license is installed on the VVX 1500D. For more information, contact your Certified Polycom Channel Partner.
