CF and DND programming pages were already introduced at version 4.1.
The new things for 4.2 are:
The Inward Dialing Modification feature allows you to alter dial strings contained in inbound SIP calls. After adding substitution rules, you can apply them to both "Called Party" and "Calling Party" SIP headers. You can implement this feature as part of the initial system setup when you Program SIP Trunks and Program SIP Phones.
External Hot desk Users (EHDUs) can now dial digits while engaged in a SIP trunk call. This enables them to access mid-call features, enter their PINs, and initiate user callbacks in a normal fashion. To take advantage of the functionality, a mechanism is required to detect the digits contained within the SIP media stream and transmit them to the MCD. This mechanism can be either your outbound proxy or the service provider's session border controller (SBC). To program this feature, add the outbound proxy or SBC as a Network Element, and then configure a SIP peer with Authentication and Key Press Event options.
The Busy Lamp Field (BLF) indicator light does not flash when a hot desk user is logged out. When a hot desk user is logged in, the lamp lights steady green. A new Class of Service option, Green BLF Lamp for Logged in Hotdesk User, controls this capability.
Night Service Indication allows supported sets to be programmed so that the Feature Access Key (FAK) LED goes off during the day and turns on at night. You can then press the key to display the current mode of operation (Day, Night 1 or Night 2).
When an EHDU has failed to log in due to a PIN validation failure three times in a five minute time span, any further login attempt will be rejected. The logout state of the EHDU may be viewed using the LOCATE FEATURE command.
Multi-Color LED line status involves employing color to indicate to a set user whether activity on a line key is of direct concern to the user, or of greater concern to another member of the associated broadcast group.
Location Based Accounting provides the capability to automatically determine a device's location based on its IP address. System administrators have the capability to attribute calls to specific locations, and bill these locations accordingly.
Account codes have been increased to support up to 40,000 Independent Account Codes.
