· Local Number Length: Default = Blank (Off). Range = Blank (Off) or 3 to 15.
Set the default length for extension numbers for extensions, users and hunt groups. Entry of an extension number of a
different length will cause an error warning within Branch Gateway Manager. This field is intended for B5800 Branch
Gateway systems where fixed length extension numbering is a requirement. Note that the Branch Prefix and the
Local Number Length must not exceed 15 digits.
· Proactive: Default = 60 seconds. Range = 60 seconds to 100000 seconds.
The B5800 Branch Gateway system sends regular SIP OPTION messages to the SM line in order to check the status of
line. This setting controls the frequency of the messages when the SM line is currently in service. Note that centralized/
survivable extensions use their own settings.
· Reactive: Default 60 seconds. Range = 10 to 3600 seconds.
The B5800 Branch Gateway system sends regular SIP OPTION messages to the SM line in order to check the
status of line. This setting controls the frequency of the messages when the SM line is currently out of service.
Note that centralized/survivable extensions use their own settings.
· Time Setting Config Source: Default = See below.
The time is either set manually (see Date and Time ), obtained using Time protocol (RFC868) requests or obtained
using Network Time Protocol (RFC958) request. This field is used to select which method is used and to apply ancillary
settings based on the selected method.
· None
Set the system to not make any time requests. The system time and date needs to be set using a phone with
System Phone Rights (User | User ). The system can then automatically apply daylight saving settings to the
manually set time.
· Time Zone: Default = Match to system Locale
The value is defaulted to match the system locale.
· Local Time Offset from UTC: Default = 00:00
This setting is used to set the local time difference from the UTC time value provided by an SNTP server. For
example, if the system is 5 hours behind UTC, this field should be configured with -05:00 to make the
adjustment. The time offset can be adjusted in 15 minute increments. If also using the daylight time saving
settings below, use this offset to set the non-DST local time.
· Automatic DST: Default = On
If enabled, the system will apply daylight saving time (DST) changes to the displayed local time.
· Clock Forward/Back Settings
This drop down lists the currently configured dates and times for the start and end of daylight savings when
Automatic DST above is enabled. Branch Gateway Manager initially applies up to 10 default values from the
current year based on the system locale. However, these should be checked to ensure that they match the
expected values and any recent changes to local DST requirements.
· Each of the 10 entries can be edited by selecting it in the drop-down list and then clicking Edit.
· An existing entry can be deleted by selecting it in the drop-down list and then clicking Delete.
· If less than 10 entries are setup, a new entry can be added by selecting <Add New Entry> from
the drop-down list and then clicking Edit.
· DST Offset
Set the amount by which the time should be changed when DST is applied or removed.
· Clock Forward/Back
This drop down can be used to set the paired dates for the start (go forward) and end (go back) of the
daylight saving period.
· Select Clock Forward and double clicking on the required date and set the Local Time to Go
Forward. Then select Clock Backward and double click on the required date and set the Local
Time to Go Back.
· Local Time to Go Forward
Set the time at which the DST Offset should be added to the local time when DST is started.
· Local Time to Go Back
Set the time at which the DST offset should be removed from the local time when DST is removed.
· Voicemail Pro/Manager
Both the Standalone Voice Mail service and the Branch Gateway Manager program can act as RFC868 Time servers
for the system. Use of other RFC868 server sources is not supported. They provide both the UTC time value and
the local time as set on the PC. The system makes a request to the specified address following a reboot and every
8 hours afterwards.
· IP Address: Default = 0.0.0.0 (Broadcast)
The address to which the RFC868 request is sent. 0.0.0.0 means default operation. In this mode,
following a reboot the control unit will send out a time request on its LAN interfaces. It first makes the
request to the Voicemail Server IP address in its configuration if set and, if it receives no reply, it then
makes a broadcast request.
