Hi, I'm a newbie here, running the V10 free version of 3CX on Win 7. I have a Grandstream GXP2110 phone amongst others and want to program the BLF, but when I go to extension>select phone>edit extension>phone provisioning the BLF fields are grayed out. I'm sure when I set up the system I had the opportunity to enter some values. Is editing the BLF fields not available in the free issue? Thanks in advance!
