BLF keys enable you to see when other users in your organization are currently on a call. For example, you can set up to 32 BLF keys on the Grandstream GXP1780 and GXP1782, which means you can view presence for up to 32 other users in your organization.

If you have one user configured on the phone, you can set each of the 4 keys to the one user, or set them as BLF keys.Rows 5 through 8 also have a default Mode. Since row 5, or key 5, is set as Information, which can also be accessed by pressing the up arrow, we’ll start by configuring this key as a BLF, and you can repeat the steps to configure additional keys.
