Configuration Settings: Extension
· SIP extensions report the type of SIP phone registered or Unknown SIP device if no SIP device is currently
registered as that extension.
· Module
This field indicates the external expansion module on which the port is located. BP indicates an analog phone extension
port on the base or control unit. BD indicates a digital station (DS) port on the control unit. For an IP Office Aura
Edition control unit, BD and BP is also followed by the slot number. VoIP extensions report as 0.
· Port
This field indicates the port number on the Module indicated above. VoIP extensions report as 0.
· Disable Speakerphone: Default = Off (Speakerphone enabled).
When selected, disables the fixed SPEAKER button if present on the phone using this extension port. Only supported
on Avaya DS and H.323 IP phones. An audible beep is sounded when a disabled SPEAKER button is pressed. Incoming
calls such as pages and intercom calls are still connected but the speech path is not audible until the user goes off-
hook using the handset or headset. Similarly calls made or answered using other buttons on the phone are not audible
unless the user goes off-hook using the handset or headset. Currently connected calls are not affected by changes to
this setting.
· Force Authorization: Default = On.
This setting is used with SIP extension devices.
· Extension Mode: Default = Local/Native
Select Local/Native for SIP extensions that are registered with the B5800 Branch Gateway system. Select
Centralized/Survivable for extensions that are registered with the Avaya Aura® Session Manager during normal
operation and only register with the B5800 Branch Gateway when in survival mode due to lose of connection to the
Avaya Aura® Session Manager.
· DID Numbers: Default = Blank
This field is optional for systems where there is a clear mapping of DID numbers to extension number, for example
DID 01555364123 and extension 884123. Another usage is if the phone registers with extension number using branch
prefix, but expects to be dialed using short format. This relies on the behavior that when SM lines are out of service, if
the branch has a call (internal or external) targeted to the SM line, it tries to first target any matching centralized
extension DID and then any centralized extension number before checking any alternative routes configured.
