Cisco 8800 Series Phones - No Voicemail Indicator on Lines on all Firmware after sip88xx.11-5-1SR1-1

Since firmware version sip88xx.11-5-1SR1-1, the voicemail indicator message and count will no longer display if the line is set to call forward all.


If the line is set to call forward all to voicemail, then it will not display the voicemail indicator count; only the call forward all indicator. If I remove the call forward all on the line, then it will display the voicemail indicator and count.

Please refer to the attached pics for reference.


How can we get this working b/c we have hundreds of lines that are set to forward to voicemail and the only firmware version that works is sip88xx.11-5-1SR1-1. Anything after this version will only display the call forward all indicator and not the actual voicemail indicator and count?

The 78XX and 79XX series phones work properly however not the 88XX series phones.


Can we get a special version added to allow new phones utilize this feature?


Is there any way that you could re-release version sip88xx.11-5-1SR1-1 to work with Cisco 88XX series phones that are beyond hardware revision V02?


We are in a hospital environment and have all of our nurse voicemail lines forwarded to voicemail as part of call trees and they need to see that there are voicemails on these lines.
