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.
