Because some features and phone buttons are not supported in SIP mode, the LED indicators and
flash rates vary. For example, when a user places a call on hold in ITP IP mode, the Call or IC button
LED uses the flutter flash to indicate that the call is on hold. In contrast, when the user places a call
on hold in SIP mode, no LED indication appears because SIP does not support the CALL or IC
buttons.
Red and Green LEDs
Mitel digital telephones have red and green LEDs in the button lamps. When both colors are used,
a green lamp generally indicates that the call is active, ringing, or holding at your phone (see below
for a possible exception for direct ring-in calls). When the lamp is red, the call is active, ringing, or
holding at another phone. Trunk access, allowed-answer permission, and the feature being used
(for example, System Hold or Call Transfer) determine if you can pick up a (red) call from another
phone.

Two system-wide programming options control these LEDs.
•
Allow Green LEDs : Gives the installer the option of having all red/green phones and red-only
phones operate the same, or allowing the red/green phones to use the green LEDs. If this flag
is enabled, the dual-color phones will use both the red and green LEDs. If it is disabled, the
phones will operate in red-only mode, like the phones without green LEDs. In the default state,
the flag is disabled.
• Use Green LEDs For Direct Ring : Determines whether direct ring-in calls cause a red or green
lamp. If the flag is enabled, direct ring-in calls to your phone will be green. If disabled, all direct
ring-in calls will cause the LED to be red. In the default state, this flag is enabled. The Allow
Green LEDs flag must be enabled in order for this flag to operate.
Headsets
For convenience, an electret headset can be used at any phone. The Speaker button is used to
connect and disconnect calls when the headset is attached. For more information about headset
use, refer to the applicable phone user guide.
Headset Power Saver Mode
Some headsets have a power-saver mode that disables the headphone after a period of silence. To
prevent these headsets from missing portions of incoming calls, there is a phone flag called “Send
Alert Burst To Headset.” Enabling this flag allows the phone to generate a tone that activates the
headset before connecting to an incoming call. In the default state, it is disabled. For more
information, refer to the “Phones and Devices” chapter in the
MiVoice Office 250 Features and
Programming Guide
