Has anyone else had any issues with Htek 920 series? I've got a 926 and 924 both on the latest firmware exhibiting the same issues. They provision via STUN and over SBC fine, register successfully and incoming and outgoing calls operate fine. None of my BLFs light up (SP1, SP2, SP3, and 2 Ext BLFs). They all function properly when pressed, but no lights. In the Web interface there is a BLF light section, and I've tweaked the default config to attempt to determine what the issue is with no luck. I've also pulled the log files and I'm getting a bunch of 403, 404 and 407s for what I think are the BLF subscribe requests. Manual configration to connect to a V14 Multi-tennant server shows proper BLF functionality. Has anyone else seen any BLF issues with Htek 900 series and V15sp4 Linux?
