Hi there, I have 2 x Yealink T46G units with the Extension module on the side. I have the keys mapped as BLF and since the upgrade to 15.5, they have not shown the phone status. Only showing an icon with a silhouette of a person, with an x through it. Has anybody else come across this issue? - Firmware is the supported version and the provisioning file is unmodified from the 3CX standard. - The keys were working as expected before the update. - I have re provisioned the phones. - I have restarted the server. Any help would be very much appreciated.
