If you are the admin of a hosted system, you have access to a wide array of features that can make handling calls easier for your team. On your browser, you can customize call features, purchase numbers, add users, configure call routing based on your organizational structure.
Even if you are working from home, you can have full access to your VoIP service’s admin portal as long as you have the login credentials. At this stage, it would also help if you printed out a call routing tree, which you can disseminate to your teammates.
