Appendix B: ITU H.323 Protocol
Overview
H.323 is a basic interface that may permit limited feature
applications accessed via in-call dialing. Certain proprietary H.323
architectures use DISA (Direct Inwards Service Access) to access
telephony services. In these systems, the handset automatically dials
the DISA number when
Start Call is pressed.
Contact your system administrator for additional information about
the exact features available in your facility.
Feature Access
Mute
The Mute feature is assigned to
FCN 1.
Custom feature programming
All other features in your H.323 system accessed via in-call dialing
are available by the appropriate dial sequence. The
Start Call key will
send the hookflash (
!) signal.
Language
If custom feature menus have been made available in multiple
languages, these will be listed on the Standby menu. Select the
desired language from the Standby menu.
Custom feature menus
When configured at the system level, two feature menus can be
activated, one from the standby state—the Pre-dial menu—and one
from the off-hook state—the Post-dial menu.
The Pre-dial menu is activated from the standby state by pressing the
MENU key. An option can then be selected from the Pre-dial menu
and the handset will dial the programmed sequence. There may be
up to 31 Pre-dial options in each programmed language.
The Post-dial menu is activated from the off-hook state by pressing
the
MENU key. An item may be selected from this menu which will
initiate the programmed dial sequence. There may be up to seven
Post-dial options per language.
If no option is selected from the menu within ten seconds, the
handset reverts to the previous standby or off-hook state. Any call in
progress when entering the Pre- or Post-dial menu will be
unaffected.
Pre-dial menu
The Pre-dial menu is used when not in an active call. The Pre-dial
menu is accessed only when the handset is in standby mode.
Post-dial menu
The Post-dial menu is available only during the off-hook state or
while in an active call. If the handset is in standby mode and the user
presses the
Start Call key, the user will hear a dial tone, indicating the
off-hook state. In many cases the Post-dial code is not operational
before a phone number is dialed, but this is managed by the PBX.
