H.323 VoIP Attributes
– PGM 130
The VOIP channels are 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 PGM also allows setting the IP TOS bit for Diffserv, a commonly recognized packet prioritization protocol.
Higher priority packets are given priority in the Router 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 Table 3.3.4.1-1 for a description of the features and the input required.
