4.3.4.1 H.323 VoIP Attributes – PGM 130
The VOIP channels are used for Distributed Networking, SIP or H.323 networks, and 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) and 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.
During a connection, DTMF Digits can
be sent in-band or out of band (H.245).
0: In band, 1: Out band, 2: 2833
