Figure 4.4.3.1-1 H.323 VoIP Attributes
The VOIP channels may be used for Distributed Networking, access to SIP or H.323 networks
and for remote iPECS devices. When the standard H.323 VoIP protocol is employed for an
external VoIP call, several attributes of these channels can be assigned. The H.323 call set-up
mode and tunneling (H.245 Encapsulation) can be established.
Also for H.323 support, a RAS (Registration, Admissions and Status) channel can be defined.
The RAS channel IP addresses (uni-cast and multi-cast) as well as the IP port Numbering Plan
and other H.323 set-up characteristics are defined.
This page also allows setting the IP TOS bit for Diffserv, a commonly recognized packet
prioritization protocol. Higher priority packets are given priority in the Default gateway or Layer 3
Switch queue. However, they are the first to be discarded in the event of long queue delays,
which may cause excess packet loss and poor voice quality.
Refer to the following table for a description of the features and the input required.
