Introduction

BLF type Prefix allows to add a certain predefined value to a dialled phone number or BLF on WorkForce/ WorkForce 5, WelcomeConsole/ WelcomeConsole 5, ForcePro 5, SuperVision 5. This predefined value is indicated in BLF Prefix, which is used before dialling a number or pressing another BLF key. For example, you can add Intercom code to BLF Prefix, label it "Intercom" and if you need to intercom a colleague on WP phone, you just press BLF Prefix (labelled Intercom) + BLF of the colleague and the two numbers are merged.

Notes:

The support of BLF type Prefix starts from WMS 6.01.20221019.4.
WelcomeConsole extension module is also supported
BLF Prefix doesn’t work for phonebook calls
BLF Prefix is not displayed on Fn keys tab in Collaboration
