Packet Marking for Media

You can set the TOS/DiffServ values that define an individual type or class of service for a given realm. In addition, you can specify:

• One or more audio media types for SIP and/or H.323
• One or more video media types for SIP and/or H.323
• Both audio and video media types for SIP and/or H.323

For all incoming SIP and H.23 requests, the media type is determined by negotiation or by preferred codec. SIP media types are determined by the SDP, and H.323 media types are determined by the media specification transmitted during call setup.
