H.323 Call Setup Info (PGM 361)
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 Registration, Admissions and
Status (RAS) 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.
H323 Call Set-up allows configuring 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 for a description of the
features and the input required).
