I am sure this is a silly thing. I have programed a lot of buttons this way but this one will not work for me. MIVB 9.4 nupoint VM, and Micollab.
I had to change a extension to another number due to conflict is the start of the issue. This person has one extension 6187 but she hot desk in to a acd extension 6636. I put a multicall button of 6187 while logged into 6636 so she can answer not acd call from that number. 6187 also has a MB. I normally put a MWI button on the 6636 so she can see she has a voicemail on 6187 and get to it. I have 20 other extension that this works on. This one however has the MWI button that says off in a square. I have the MB set up in nupoint. I also deleted it and let micollab create the MB also (same results). I cannot find anywhere what this off is and why it is on this button. Thanks for the help
