Soft Key Transfer Type ** (See note below) Sets the default value for the type of transfer invoked using the Transfer softkey on Nortel sets.

Attended: This is the default setting for new systems. This mode enables the XSTIM based softkey user interface for collecting and editing dialed digits. The Transferor has the option of talking with the Transfer-to party prior to transferring the call and can complete or cancel the transfer using softkeys.

Asterisk Blind: In this mode, digit collection is performed using inband signaling and there are no options to cancel the transfer. The Transferor does not have the option of talking with the Transfer-to party prior to transferring the call.
Asterisk AttendedIn this mode, digit collection is performed using inband signaling. Once the transfer-to number has been dialed, context-sensitive softkeys will be presented to the transferor for completing the transfer, canceling the transfer, or conferencing both parties into a three-way call.

Note: this setting will be used for ALL XSTIM extensions that have not explicitly been assigned a Softkey Transfer Type setting in the Extensions (Nortel) configuration page. Take care when changing this setting on an existing system.
Attended Transfer Number ** (see note below) The caller ID number used for attended transfers.
First Line for Calls Without Name

Contents of the first display line of a Nortel phone when the phone receives an incoming call from an endpoint with an unknown caller ID name. By default, the CallerID number is shown on both the first and second line.

This setting applies only to phones with 3 line displays (e.g. 1140E).

Ringing BLF Active+Ringing State This option controls the state reported on a ringing BLF key when the target phone is on an active call and another incoming call is alerting on the target phone. Any sets with a ringing BLF associated with a target extension that is already busy when another call arrives for that extension will not provide a ringing alert while the setting is configured as Active (which is the default).  When set to Ringing the sets with a Ringing BLF will provide audible ringing regardless of the original state of the target extension.
