Skype is great for home and work and lets you connect with millions of people to grow your business. If you want to use Skype at work, you have two options – either use the same Skype that you use at home or use Skype for Business.
The Skype that you use at home is great for smaller businesses of up to 20 employees. It is free to use, unless you want to buy credit to make calls to landlines and mobiles.
Skype for Business lets you add up to 250 people to online meetings, gives you enterprise-grade security, allows you to manage employee accounts, and is integrated into your Office apps.
