About Lync / Skype for Business servers

All System locations and Pexip Distributed Gateways can have a nominated Lync / Skype for Business* server. This can be a Front End Server or a Director; it cannot be an Edge Server. The nominated Lync server will be used for outbound MS-SIP calls.

Outbound calls are made from Pexip Infinity when:

• a conference participant uses an Infinity Connect client to add another participant to the call
• the administrator manually dials out to a participant from a Virtual Meeting Room
• a participant is automatically dialed out to from a Virtual Meeting Room
• a third party uses the API to place a call to a participant
• the Pexip Distributed Gateway is used to interwork a call.

For more information on integrating Pexip Infinity with Microsoft Lync, see Integrating Microsoft Lync / Skype for Business with Pexip Infinity.

To add, edit or delete Lync servers, go to Call control > Lync Servers.
