Considerations
When using this feature the following must be taken into consideration:
• If there is an incoming call on a BLF/List-monitored extension, the corresponding ring tone will play only if all of the
regular lines are in an idle or hold state and both paging and conf/xfer is not active.
• The BLF/List-related ring tone will stop playing if a regular line starts dialing, starts ringing, is unheld, or if paging is
activated. The BLF/List-related ring tone will resume when the phone is in an idle state and paging is not active.
• If multiple BLF/List-monitored extensions are ringing simultaneously, they are placed in a queue based on the ringing
start time and priority is given to the extension that rang first. For example, if BLF/List is configured for extension 1,
extension 2, and extension 3, and all three receive incoming calls in sequence, the phone will play the ring tone for
extension 1. If ringing stops for extension1, ringing will begin for extension 2, and so on.
• Call waiting tone playback behavior for BLF/List-monitored extensions is based on the same rules as regular lines, but
the call waiting tone for BLF/List-monitored extensions will also be played/stopped when paging is activated/deacti-
vated.
Configuring Ring Splash Settings
Use the following parameters to configure the ring splashsettings:
BLF Subscription Period
On the IP phones, you can set the time period, in seconds, that the IP phone re-subscribes the BLF subscription service.
In the configuration files, enter the following parameter with a valid value to set the BLF subscription period:
sip blf subscription period: <value in seconds>
The minimum value for this parameter is 120 seconds (2 minutes) and the maximum is 2147483647 seconds. The default
is 3600 (1 hour). The phone resubscribes to the BLF subscription service before the defined subscription period ends.
You can configure this feature using the configuration files or the Mitel Web UI.
