It’s a good practice for each of your team members to have their own personal business phone numbers. There are many reasons why they shouldn’t use their personal cell phone number for business, so you’ll want to give them their own phone number through your VoIP provider or phone system.

The Busy greeting is played when you are on another call and do not have call waiting, and the No Answer greeting is played when you do not answer the call.
