Other MLPP service features
The MLPP service also includes the following features:
• Call Origination Busy
• Re-authorization
• Speakerphone exclusive to 911 Emergency
Call Origination Busy
The Call Origination Busy feature prevents incoming calls from disrupting your outbound call
address entry sequence. If enabled, this means that if you are placing an outbound call either
by lifting the receiver and entering digits or your phone is on-hook and you are entering digits,
you cannot be disturbed by any incoming call.
Re-authorization
With the re-authorization feature, you are asked to re-enter your password if your user
password changes (changed by administrator) while you are logged in to your IP Deskphone.
Previously, you would have had no indication that your password had been changed and would
have constantly seen error messages when trying to place a call. The Reauthorization feature
lets you enter your new password without having to log out of your IP Deskphone.
Speakerphone exclusive to 911 Emergency
If this feature is enabled, speakerphone is allowed only for making 911 Emergency calls or
receiving calls from the 911 Emergency operator. The speakerphone restriction is applicable
to both the Handsfree key and line keys. As well, when this feature is enabled, the Answer soft
key is not displayed for an incoming call and you cannot answer a call by pressing the
Handsfree key or line key, except for calls from the Emergency 911 operator. To answer any
other call, you must go off-hook.
During an active call, you cannot go handsfree by pressing the Handsfree key.
Making a call with MLPP
If your IP Deskphone is configured for MLPP, the display screen is enhanced for making and
receiving precedence calls. There are several ways to make outgoing calls from your IP
Deskphone with MLPP, as follows:
• Make a call by going off-hook.
• Make a call by using an entry in the inbox or outbox call logs.
• Make a call from the personal and global Address Book, or from your Friends list.
