Prestige 2002 Series User’s Guide

Your Prestige can add IEEE 802.1Q VLAN ID tags to voice frames that it sends to the network. This allows the Prestige to communicate with a SIP server that is a member of the same VLAN group. Some ISPs use the VLAN tag to identify voice traffic and give it priority over other traffic.

6.5 QoS Configuration

Click VoIP in the navigation panel and then QoS to display the following screen.

	SIP.
RTP TOS Priority	Type a priority for voice transmissions. The Prestige applies Type of Service
	priority tags with this priority to RTP traffic that it transmits. Priorities 6 and 7 are

	group to communicate with the SIP server.
