Running 3CX with aastra template for 6755i, tried 3.2, 3.2.2, 2.6 frimware for aastra phone, here is the issue. Call comes through I answer and put on park, blf light lights up normally, I can do this at will the FIRST time a call comes in. Any other call after this when I put call on park the BLF does not light up at all even though the call is parked. We can pickup and park calls but light does not illuminate anymore. We have to reboot phone in order to get it working again, only to have it repeat the issue. Any ideas?
