BLF Light on when they aren't on a call



We have been experiencing an issue where occasionally the BLF red light on our Polycom VVX410s is red for a certain line even though that line isn't on the phone or speaking to anyone. 


For example right now on everyones 410s with expansion module there are two peoples lines who are red even though neither of their phones are in use.


Any ideas on how to fix this issue?

Hello UltrasonicWelders,

welcome back to the Polycom Community.

A couple of your old posts => here <= are still open / pending as you have not marked these as "Accept as a solution".


If they are in this state nobody finding them via a community search will know if an answer or advice was useful and has helped you.


Could you therefore kindly go over them and mark or answer as appropriate ?


If they are marked as "Accept as a solution" other users can find these easier and it helps them to utilize the community more efficiently. 



In addition not stating the currently used software does not help others when finding this post in days, weeks, months or years to come as they do not know what software you utilised at the time of writing. Please therefore always post the exact complete build id.
