Forward Teams phone to voicemail, but not Teams audio calls
Currently, if you forward your Teams Phone (external VOIP calls) to voicemail, all of your internal Teams Audio calls (employee to employee with no telephone number) are also forwarded to voicemail. I would suggest handling them separately. Forward to voicemail for telephone VOIP calls, but use the presence / do not disturb to avoid internal audio calls. I get many cold calls from vendors each day and want to forward my telephone, but not my Teams audio from internal colleagues.
