I have Elastix 1.6 running with several Yealink D28P phones deployed. The BLF's on those phones are a little buggy, so I've deployed a Cisco SPA509G as a test. It's up to date on its firmware and it registers fine and tests ok except for the BLF function. here is my setup within the phone tab of the SPA509G: Extensionisabled Share Call Appearancerivate Extended Function:fnc=blf+sd;sub=401@$PROXY;ext=401@$PROXY the speed dial works ok, but the LED stays orange no matter what is happening with the extension I wish to monitor (401). Any help would be appreciated.
