Does anyone know if it is possible to change the "message from:" field information in a CUE voicemail notification email? The caller number comes across but not the name.
No, CUE only has a database of internal users that have mailbox on the system. AFAIK, there isn't any workaround. I will check with CUE team to see if they have any enhancement on their roadmap.
The "Message From:" field will include name only for internal callers - i.e. if there is a match against the internal CUE database.
