Voice Message light not working on Phones?

Good Morning,

I have recently installed the latest Disto download on a site and have noticed both with Yealink and Cisco phones the Voice message light fails to work when a voicemail is left?

Has any one else seen this problem?

I am running;
1.86.29.55-1

Thanks

Anybody have insight on this i am running this issue to with a Polycom 450/ Aterisk CLI 2.10.0.1 FreePBXEnabled.
