About Lync / Skype for Business servers

Pexip Infinity uses Lync / Skype for Business* servers to route outbound MS-SIP calls.

Outbound calls are made from Pexip Infinity when:

You can configure the addresses of one or more Lync servers within Pexip Infinity. These can be Front End Servers or a Directors; they cannot be Edge Servers.

Within an on-prem Lync / Skype for Business environment, you must then associate a specific Lync server with a System location or Call Routing Rule to instruct Pexip Infinity to use that Lync server when it places an outbound MS-SIP call from a Conferencing Node in that location, or when it matches that routing rule.

Within a public DMZ Lync / Skype for Business deployment, you must ensure that a Pexip Infinity location is not configured to route calls to a specific Lync server. This is to ensure that each Conferencing Node uses DNS to locate an appropriate Lync system via which to route outbound calls.

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

The available options are:

Option Description
Name The name used to refer to this Lync server in the Pexip Infinity Administrator interface.
Description An optional description of the Lync server.
Address The IP address or hostname of the Lync server.
Port

The IP port on the Lync server to which the Conferencing Node will connect.

Default: 5061.

Transport

The IP transport used to connect to the Lync server.

Default: TLS.

To associate a Lync server with a System location, go to Platform configuration > Locations, and to associate it with a Call Routing Rule, go to Service configuration > Call routing.
