Hi Guys, I'm new to 3CX and I'm currently testing the system with two Yealink phones (T46G and T42S). I have a BLF key to monitor each phone's extension. I also have 3 shared parking keys (SP 1, 2, 3) on each phone. The problem I'm having is that the LED lights are not lighting up to show the status of the key. I have checked everywhere and can't find a solution for this. Both phones are remote phones on the same network and they are not behind a firewall. I can place/receive calls with no issues. I can use the BLF and SP keys to transfer calls. Everything else seems to be working properly except for the LED lights. Can somebody point me in the right direction? Thank you in advanced!
