If you have network administration experience, you can use Skype for Business to
- Manage all live communications among users within and outside of your organization
- Connect users for sharing Office documents and IM and voice conversations

- Instant messaging: Users inside and outside of an organization can use IM over the Skype for Business desktop clients. They can also use a web-based interface to connect with most popular IM clients.

- Office integration: You can use and distribute PowerPoint presentations within a web conference. Users can edit Office documents in real time locally or remotely. Skype for Business Server options also appear in the interfaces of Office applications.
- Live audio and video conferencing: Skype for Business Server is compatible with Microsoft RoundTable or any device that supports Real-time Transport Protocol (RTP) or Real-time Transport Control Protocol (RTCP).
- Encrypted communication: Transport Layer Security (TLS) and Secure Real-time Transport Protocol (SRTP) protect sensitive information without limiting software functionality and eliminate the need for remote users to establish virtual private network (VPN) connections.

- Standard CAL: For IM, presence, or PC-to-PC audio and video communications.
- Enterprise CAL: For audio, video, and web conferencing; desktop sharing; room systems; and multiple HD video streams. Enterprise CALs can only be used in conjunction with Standard CALs.
- Plus CAL: For enterprise telephony features. Plus CALs can only be used in conjunction with Standard CALs.
