Signaling Settings Local Cluster Configuration

Polycom, Inc. 71

If H.323 signaling is enabled, the Polycom DMA system’s Call Server operates

as a gatekeeper, receiving registration requests and calls from H.323 devices.

If SIP signaling is enabled, Call Server operates as a SIP registrar and proxy

server, receiving registration requests and calls from SIP devices. If both are

enabled, the system automatically serves as a SIP <–> H.323 gateway.

Either H.323, SIP, or both must be enabled in order for the DMA system’s

Conference Manager to receive calls for multipoint conferences (virtual

meeting rooms, or VMRs) and distribute them among its pool of MCUs.

On this page, you can also:

•Turn on H.235 authentication for H.323 devices.

•Turn on SIP digest authentication for SIP devices.

•Click a Device authentication settings link to go to the Device

Authentication page, where you can configure SIP device authentication

and maintain the inbound device authentication list for both H.323 and

SIP devices (see “Device Authentication” on page 264).
