Hello,
As mentioned, if the user has a display phone -
on hook.
press message waiting light.
message says call me back.
select yes option.
display says call speed dial to voicemail (if it was a callback error)
select erase.
If not using a display phone, from call xpress deactivate the MWI in the users voicemail account (callxpress - administration). Apply changes. And then reactivate MWI.
I had both our PBX and CallXpress voicemail vendor look at this situation for us. It had to do w/ the way the call xpress syncs the MWI lights every night. We use dialogic cards for voicemail ports. I was told IP integration on our voicemail platform would take care of the issue.
