I have Nokia lumia 730. It has windows phone 8.1 OS. By mistake one of my contact get's added in VoiceMail. When I call to that number it shows me the name voicemail in dial history. I want to remove this contact from voicemail. How can I remove?
To edit the voicemail number, go to Settings, swipe over to applications and select "phone". Alternatively, open the Phone app, expand the app bar by tapping on "..." and select "settings".
Once there, you can change the voicemail number to something else.
Note that there doesn't currently seem to be any way to delete the voicemail number. If you empty the textbox, the phone will automatically switch to the default voicemail number, which is either set by your carrier or the first one you entered manually. In your case it's probably still your contact's phone number, so currently you'll have to disable the "Use default voicemail number" option and manually set the voicemail number to something else. It can be a fictional/invalid number, or maybe your carrier's actual voicemail number (even if you don't have voicemail service).
