We are currently investigating a reported issue affecting the BLF (Busy Lamp Field) functionality on some IP phones. Users may experience delays or failure in BLF status updates, such as incorrect or missing presence indicators (e.g., busy/available/idle). This may affect the call transfer, call pick up in some situations. Our engineering team is actively working to identify the root cause and restore full functionality as soon as possible.

The issue with the BLF (IP handsets expansion panel key lights) has been resolved. The root cause of the issue was the sheer amount of Subscribe requests received from the handsets. We are planning maintenance windows over the weekend to improve the infrastructure configuration and avoid these issues happening again. Sincere apologies to anyone affected.
