is possible to create a System Speed Dialling directory for a site by grouping all extensions at that
site as a tenant (® 5.1.3 Tenant Service).
Networks that span multiple time zones
The time zone is set independently for each PBX in a One-look network. The PBX can acquire the current time
either automatically from the Master unit, an NTP (Network Time Protocol) server or caller ID information over
ISDN, or the time can be set manually.
Certain PBX features use the local PBX’s time information during operation, and other features use the Master
unit’s time information. The following table lists which features use which time information:
Feature Time Source
Times in the Incoming log Local PBX
