Configuring Verba for Mediation / AVMCU based recording

This article provides a detailed step by step guide on how to configure the Verba Recording System for Mediation / AVMCU based recording in a Microsoft Lync/Skype for Business environment.

When using Mediation / AVMCU based recording, calls are not rerouted, the call media path is not altered by Verba in any way. Media Collectors installed on the Lync Mediation / AVMCU servers are responsible for sending call media streams to the Recording Servers.

Important note on terminology

Traffic collection is managed by the Verba Recorder Proxy service operating in Remote Capture mode.
When configured this way, the service is not an active part of the call media path. It only captures the media streams that normally pass through its location (in this case the Mediation / AVMCU Server).

Preparation

Before starting to configure Verba for Lync recording, every Verba server and component have to be installed. For more information about the required servers and components see Call recording for Microsoft Lync and Skype for Business.

Firewall configuration

Refer to Firewall configuration for Skype for Business - Lync deployments for more information.
