The BLF feature, offered by Data Fanatics, allows users to monitor the status of other extensions in real-time. This feature displays the status of each extension, such as whether it is busy or available, on the user’s phone. The user can then easily determine which extensions are available to receive calls and which ones are already in use. This is especially useful for team collaboration, as it helps team members to quickly and efficiently transfer calls to the appropriate extensions without having to make multiple attempts. In addition, BLF can also be used to park calls, allowing users to place calls on hold and retrieve them from any other extension. This feature provides increased efficiency and productivity, making it a valuable tool for any business or organization. With the BLF feature from Data Fanatics, users can streamline their communication and optimize their workflow.
