I have over 120 unread voice mails on my desk phone, they were all listened to on the mobile app, which doesn't sync with the desk phone... If I delete them online, will they be deleted on the phone too AND vice versa?
When you delete a message on any device it should delete from the account and every other device. When checking your messages away from work, are you using the RingCentral Phone app, or are you calling your RingCentral number and pressing star (*)?
