Network Quality - Polycom realpresence group series Administrator's Manual

Notes: AS-SIP restrictions
Consider the following restrictions when you enable AS-SIP on a RealPresence Group system:
• Be sure to register the system only to AS-SIP-aware proxy/registrar servers, because AS-SIP
signaling can be incompatible with other types of proxy/registrar servers.
• If the Cisco Telepresence Interoperability Protocol (TIP) software option is installed, turn off TIP
signaling on the RealPresence Group endpoint by going to Admin Settings > Network > Dialing
Preferences > Dialing Options and disabling the TIP setting. TIP signaling is incompatible with
AS-SIP signaling.

Network Quality

Set the Network Quality options for the way your network handles IP packets during video calls.
To configure quality of service settings:
1 In the web interface, go to Admin Settings > Network > IP Network > Network Quality.
2 Configure these settings.

Description
Specifies your service type and lets you choose how to set the priority of IP packets
sent to the system for video, audio, FECC, and OA&M:
• IP Precedence—Represents the priority of IP packets sent to the system. The
value can be between 0 and 7.
• DiffServ—Represents a priority level between 0 and 63.
Note: If AS-SIP is enabled and you select DiffServ, the DSCP values for audio and
video defined for the negotiated call precedence level in the default network domain
that was configured for outbound calls override the Video and Audio settings
defined on this page of the web interface. If you have not enabled AS-SIP, the Video
and Audio values defined here are used.

RTCP traffic.
Specifies the IP Precedence or Diffserv value for audio RTP traffic and associated
RTCP traffic.

following channels:
• H.323—H.225.0 Call Signaling, H.225.0 RAS, H.245, Far End Camera Control
