When looking for matches from the Redial List and the Directory, the SPA-841 will skip any leading
*codes, so that the match is purely based on the target number. The *code that will be skipped are (if
configured in the phone):
•
All call forward activation and deactivation codes
•
Secure call activation and deactivation codes
•
Block CID activation and deactivation codes
•
Block anonymous call activation and deactivation codes
•
DND activation and deactivation codes
•
All the Prefer codec and Force codec codes
•
Referral services codes and Feature Dial Services codes
Time/Date
The SPA-841 obtains the current time information from one of the following ways:
•
NTP Server – One or two NTP servers can be configured to the phone. When it first boots up, the
phone will try to contact the NTP server to get the current time. Then the phone periodically
synchronizes the current time with the NTP server. The synchronization period is fixed at 1 hour.
In between the update, the phone tracks the time with its own internal clock.
•
SIP Messages – Each SIP message (request or response) sent to the SPA may contain a Date
header with the current time information. If the header is present, the SPA will use it to update its
current time.
•
Manual Setup – SPA-841 also allows the user to manually enter the current time and date from
the phone GUI or from the web page. However, this value will be overridden by the NTP time or
SIP Message Date whenever they are presented to the phone. Manual setup requires the user to
enter the time in 24 hour format only.
Note that the time served by the NTP Server and the SIP Date Header are GMT time. The local time is
obtained by offsetting the GMT according to the time zone of the region. <Time Zone> can be configured
from the web page or provisioning. This time can be further offset by <Time Offset (HH/mm)> parameter,
which must be entered in 24 hour format only. This parameter can be configured from the Phone GUI
also.
The <Time Zone> and <Time Offset (HH/mm)> offset values are not applied to the manual time/date
setup.
Daylight Saving Time
The SPA-841 supports auto adjustment for daylight saving time. To enable this feature, the administrator
must configure the <Daylight Saving Time Rule> (regional) parameter. This parameter is a rule with three
(3) fields. Each field is separated by semicolon (;) as shown below:
start=<start-time>;end=<end-time>;save=<save-time>
where
<start-time>
and
<end-time>
are of the form
: <month>/<day>/<weekday>[/HH:[mm[:ss]]]
<save-time>
is of form:
[/[+|-]HH:[mm[:ss]]]
<month> =
1,2,3,…,12 (for Jan, Feb, …, Dec)
