I am using 3CX commerical edition and have a problem that has me at a loss. I have several different brand phones on the system but I am using a Aastra 57i for a receptionist station with a 560M sidecar. Any GXP-2000 (there are three) on the system always shows as being busy on the BLF fields on the Aastra. BT-100's, Polycoms, and a grandstream ATA appear to all report to the BLF list on the Aastra fine, it appears only to be the GXP-2000's. I cannot find any setting that governs this funcationality on the GXP-2000 and I am presupposing that it is on those phones that the issue lives. Any ideas?
