System Default Codecs - Avaya IP Office H.323 Telephone Installation Manual

2.2.5 System Default Codecs

By default, all VoIP devices added to the IP Office configuration use the system's default codec preferences. This is shown
by the Codec Selection setting on an IP trunk or extension being set to System Default.
In addition to changing the default codec preference order for all VoIP trunks and extension, the codec preferences used
by a particular trunk or extension can be adjusted. However, the use of the common system settings ensures codec
consistency between trunks and extensions.
Changing the Default Codec Preferences
1. Using IP Office Manager, retrieve the configuration from the system.
2. Select System.
3. Select the Codecs sub-tab.
4. The Available Codecs list shows which codecs the system supports. The codecs in this list which enabled are
those that can be used in other configuration forms including the adjacent default selection.

codec lists where it was being used.
5. The Default Selection section is used to set the default codec preference order. This is used by all IP (H.323 and
SIP) extensions and lines on the system that have their Codec Selection setting set to System Default. This is
the default for all new added IP extension and lines.
6. If these settings need to be changed, do so and then save the configuration back to the system.
