Is there a general mailbox or does there have to be a separate extension purchased for this purpose? Also, does an extension have to be associated with a Skype nunber or can it be forward to a cell phone number?
there is a general vm box in the event of after hours messages. An extension can be a skype id and/or a regular phone number. Your employee does not need to have skype, in the first field of the employee profile, you can put a regular number. Just remember to have Skype Out credits (subscriptions won't work) on the Skype Business Account first.
