Configuration Settings: System
· Media Security (H.323): Default = Disable. Release 6.x+
This setting defines the Media Security setting for all H.323 extensions whose Media Security field is set to the value
System Default. Note that Secure RTP (SRTP) is not supported on H.323 lines. When a new H.323 extension is
added, the default setting in its Media Security field is System Default, for which the operation is determined by the
setting that is defined here. The Media Security (H.323) options are:
· Disable – Media security is not required. All media sessions (audio, video, and data) will be enforced to use RTP
only.
· Enforce – Media security is required. All media sessions (audio, video, and data) will be enforced to use SRTP
only.
· DSS Status: Default = Off
This setting affects Avaya display phones with programmable buttons. It controls whether pressing a DSS key set to
another user who has a call ringing will display details of the caller. When off, no caller information is displayed.
· Auto Hold: Default = On.
Used for users with multiple appearance buttons. When on, if a user presses another appearance button during a call,
their current call is placed on hold. When off, if a users presses another appearance button during a call, their current
call is disconnected.
· Dial By Name: Default = On
When on, allows the directory features on various phones to match the dialing of full names. When off, the directory
features use first character match only. See User Directory Access .
· Show Account Code: Default = On
This setting controls the display and listing of system account codes:
· When on: When entering account codes through a phone, the account code digits are shown while being dialed.
· When off: When entering account codes through a phone, the account code digits are replaced by s characters on
the display.
· Inhibit Off-Switch Forward/Transfer: Default = Off (Italy = On)
When enabled, this setting stops any user from transferring or forwarding calls externally. See Off-Switch Transfer
Restrictions .
· Restrict Network Interconnect: Default = Off.
When this option is enabled, each trunk is provided with a Network Type option that can be configured as either
Public or Private. The system will not allow calls on a public trunk to be connected to a private trunk and vice versa,
returning number unobtainable indication instead.
· Drop External Only Impromptu Conference: Default = Off.
If selected, when the last remaining internal user in a conference exits the conference, the conference is ended,
regardless of whether it contains any external callers. If not selected, the conference is automatically ended when the
last internal party or trunk that supports reliable disconnect exits the conference. The Inhibit Off-Switch Forward/
Transfer option above is no longer applied to conference calls.
· Visually Differentiate External Call: Default = Off.
This setting is applied to the lamp flashing rate used for bridged appearance and call coverage appearance buttons on
1600 and 9600 Series phones and on their button modules. When selected, external calls alerting on those buttons will
use a slow flash (200ms on/50ms off). If not selected or if the call is internal, normal flashing (500ms on/500ms off) is
used.
· Unsupervised Analog Trunk Disconnect Handling: Default = Off.
When using analog trunks, various methods are used for trunk supervision, ie. to detect when the far end of the trunk
has disconnected and so disconnect the local end of the call. Depending on the locale, the system uses Disconnect
Clear signalling and or Busy Tone Detection. This setting should only be enabled if it is know that the analog trunks do
not provide disconnect clear signalling or reliable busy tone. When enabled:
· Disconnect Clear signalling detection is disabled. Busy tone detection remains on.
· Unsupervised transfers and trunk-to-trunk transfers of analog trunk calls are not allowed. The Allow Analog
Trunk to Trunk Connect setting on analog trunks (Line | Analog Options ) is disabled.
· If Standalone Voice Mail is being used for external call transfers, Supervised Transfer actions should be used in
call flows rather than Transfer actions.
· High Quality Conferencing: Default = On.
Supports the use of the G.722 codec . IP lines and extensions using G.722 are provided with wide band audio. If
High Quality Conferencing is enabled, when several wide band audio devices are in the same conference, the
system will ensure that the audio between them remains wide band, even if the conference also contains other lines
and devices using narrow band audio (analog devices, digital devices and IP devices using codecs other than G.722).
· Strict SIPS: Default = Off. Release 6.2+
This option provides a system-wide configuration for call restrictions based on SIPS URI.
· When this option is off (unchecked), calls are not rejected due to SIPS. A call is sent according to the configuration
of the outgoing trunk or line that it is routed to, regardless of the way the call came in, even if the call came in as
a SIP invite with SIPS URI and is being sent with a SIP URI onto a non-secure SIP trunk.
