BLF Page Switch Feature
A new features enables the 6735i, 6737i, 6739i, 6755i, 6757i, 6757i CT, and 6867i model phones to automatically switch
the screen focus to a softkey page or M675i expansion module page that has an active Busy Lamp Field (BLF or BLF/List
key(s). Administrators can configure this feature using the “blf activity page switch” parameter.
If this parameter is set to “1”, the screen will switch to a softkey page or an M675i expansion module page if a monitored
extension transitions to a ringing (fast flashing) state. If this parameter is set to “2”, the screen will switch if a monitored
extension transitions to either a ringing (fast flashing) or a hold (slow flashing) state. Finally, if this parameter is set to “3”,
the screen will switch if a monitored extension transitions to either a ringing or hold state OR from an idle (off) state to
an “in call” (solid) state.
The following can be observed with this new feature:
• If there is a lot of activity on the monitored extensions, the page will be shown on the screen for at least 5 seconds
before switching again. When a user manually scrolls the pages by pressing the More key or the Function key (for the
page you want to display) on the M675i, no activity-triggered page flipping should occur for 5 seconds after the man-
ual switch.
• If the phone softkeys are hidden by an overlay screen, such as an XML UI object, a menu (e.g. the Services, Directory,
or Callers List menu), or if the phone is in an active call, the screen will not automatically switch focus to a softkey page
with BLF activity (it will however for an expansion module page).
• When the phone is in Idle mode, the menu switches to the page with the BLF key when there is an incoming call to the
monitored extension. The page is shown for 10 seconds if the call is answered. If the call is not answered by the BLF
extension, the BLF key page will be shown as long as ringing is ongoing.
• When the BLF key page is shown and there is another incoming call on another BLF key on the same page, the new
call is also shown on this BLF key.
• When the BLF key page is shown and there is another incoming call on another BLF key on another page, the switch
to the other page will be done after 10 seconds.
• When the BLF key page is shown and there are several more incoming calls on BLF keys, after 10 seconds the next
active BLF key will be shown in the key number order.
8. In the "BLF List URI" field, enter the name of the BLF list defined on the BroadSoft BroadWorks Busy Lamp field page for your particular user.
For example, sip:9@192.168.104.13.
Note:
The value of the BLF/List URI parameter must match the list name configured. Otherwise, no values display on the 6757i screen and the fea-
ture is disabled.
9. Click Save Settings to save your changes.
Note:
Applicable to the 6735i, 6737i, 6739i, 6755i, 6757i, 6757i CT, and 6867i IP Phones only.
Notes:
• To minimize the chance of a lot of switching between the Idle screen and the page(s) with BLF keys, it is recom-
mended to have the BLF keys with most frequent traffic on one page. If the expansion module has several BLF keys,
it is recommended to use an extra display panel unit.
• The IP phones (as well as the M675i Expansion Module) will automatically switch to the idle page (or the first page on
the M675i Expansion Module) if no BLF activity is detected by the phone.
