The IP Office control unit contains a battery backed clock which is used to maintain system time during normal operation and when mains power is removed. The time is normally obtained using Time protocol (RFC868) requests. Note that this is different from Network Time Protocol (NTP).
Following a reboot the IP Office control unit sends out a time request on its LAN interfaces. It first makes the request to the Voicemail Server IP address in its configuration and, if it receives no reply, it then makes a broadcast request.
The Voicemail Lite server (pre-IP Office Release 5 only), Voicemail Pro server and the Manager program can all act as Time servers, giving the time as set on their host PC. If you are running Manager when the Voicemail Server starts, then Voicemail does not start as a time server. It is therefore recommended that you have no copy of Manager running when you start or restart the Voicemail Server.
A specific address for the time server that should be used can be set in the IP Office configuration using the Time Server IP Address (System | System) setting. Setting this address to 0.0.0.1 also disables the IP Office's time update requests.
When using a time server located in a different time zone from the IP Office, there are two mechanisms for applying an offset to the time. If Manager is acting as the time server, the time offset for each can be specified through the Time Offset of the BOOTP entry for the system. Alternatively, the offset can specified in the IP Office configuration using Time Offset (System | System).
Manually Setting the System Time
For IP Office systems without access to a time server, a number of methods to manually set the system time exist. These are available in the IP Office 4.1+. The following method is only supported on these phones: 2410, 2420, 4412, 4424, 4612, 4624, 4610, 4620, 4621, 5410, 5420, 5610, 5620, 5621, 6412, 6424. It is supported on any analog, T3, T3 IP or wireless (IP DECT, 3600, 3700 Series) phones.
| • | Note: If the IP Office system that is still configured for automatic time updates (on by default), any manually set time and date will be overridden on the next automatic update. The use of automatic updates can be disabled by setting the System | System | Time Server IP Address to 0.0.0.1. |
Enabling a User Button for Time and Date
| 1. | Select the user who can adjust the system time and date. |
| • | If necessary create a new user who can be used to log in and set the time and date before logging out. |
| 2. | On the User | Telephony tab, ensure that the option System Phone is selected. |
| 3. | On the User | Button Programming tab select and double-click on an available button. |
| 4. | Select Emulation > Self-Administer as the action. |
| 5. | In the Action Data field enter 2. |
| 6. | Enter an appropriate label for the button. |
| 7. | Adding another button set to the Emulation > Time of Day action is recommended as this will allow the user to view and confirm the systems current time. |
| 8. | Send the updated configuration to the IP Office. |
Using the Programmable Button
| 1. | Press the programmed button. If the user has a Login Code set it is requested. |
| 2. | The options Date and Time are displayed. |
| 3. | To set the date press Date. |
| 1. | The current system date is displayed. |
| 2. | Enter the new date, using two digits for day and month. Use the * or # keys to insert the / separators. The format for date enter matches the locale of the IP Office system. |
| 3. | During entry the key labeled <<< can be used to backspace. |
| 4. | When the full date has been entered as required, press Next. |
| 6. | The phone will return to idle. |
| 4. | To set the time press Time. |
| 1. | The current system time is displayed. |
| 2. | Enter the new time using 24-hour clock format. Use the * or # keys to insert the : separator. |
