In order to complete the steps below, you must have a System Administrator role in Verba. 

The registration consists of the following steps:

Recording architecture

The following diagrams show the connections in a highly available Microsoft Teams IM recording environment when using the Webhook/DLP API (left), and Export API (right).

File Queue Setup for Load-balancing and Failover

When there is only a single recorder, the value of the "Number of Processing Queues Owned by Recorder Role" and the "Number of Receiving Queues Owned by Director Role" settings will be the same, and it will be equal to the total number of cores of the server multiplied by two. 

When there are multiple Recording Servers, and there is load-balancing between them, then the value of these settings will be different. 

The "Number of Receiving Queues Owned by Director Role" setting has to be the same on all Recording Servers (Recording Directors). This setting has to be the same as the total active Recording Server (Media Recorder) cores multiplied by two.

Number of Receiving Queues Owned by Director Role = Total Active Recording Server cores * 2
or
Number of Receiving Queues Owned by Director Role = Number of Processing Queues Owned by Recorder Role setting * number of recorders

The "Number of Processing Queues Owned by Recorder Role" setting also has to be the same on all Recording Servers (Media Recorder). But instead of the total active cores, this setting is always equal to the number of CPU cores of the individual Recording Servers (Media Recorders) multiplied by two.

Number of Processing Queues Owned by Recorder Role = Individual Recording Server cores * 2

For example, if there are two Recording Servers with 4 CPU cores each, then the "Number of Processing Queues Owned by Recorder Role" setting will be 8 on each servers (Media Recorders), and the "Number of Receiving Queues Owned by Director Role" setting will be 16 on each servers (Recording Directors).

If there are three Recording Servers with 4 CPU cores each, and one of them is standby (N+1), then the numbers will be the same. The "Number of Processing Queues Owned by Recorder Role" setting will be 8 on each server (Media Recorder), and the "Number of Receiving Queues Owned by Director Role" setting will be 16 on each server (Recording Director).

Configuration

Prerequisites

Assigning a Public IP Address (Webhook/DLP API only)

For a single non-HA setup, the Recording Server (Recording Director) needs to have a public IP address. In the case of a highly-available setup, the public IP address has to be assigned to the load-balancer.

Creating an App Registration in Azure

Before configuring the Verba Recording Server(s) for Microsoft Teams Chat recording, an App Registration has to be created in Azure. For the configuration steps, see: 

Registering an App for Microsoft Teams Chat Recording in Azure

Creating the File Queue folder

A root folder has to be created for the processing queues. In the case of a single-recorder setup, this folder can be created on the local disk of the server (recommended path: [APPLICAION_FOLDER]\processing_queue). In the case of a HA setup, the processing queue folder cannot be created on the local disk of the Recording Server. Instead, it has to be created on a separate network location accessible from all servers.

Assigning Certificates (Webhook/DLP API only, optional)

For the connection encryption certificate, both publicly signed and locally generated certificate works. Only CSP certificates are supported (CNG/KSP certificates are not supported). The SAN configuration of the certificate must include the public address of the Recording Server, or the load-balancer in the case of multiple Recording Servers. Using an asterisk in the SAN is accepted. The private key of the certificate has to be exportable.

Configuring Microsoft Teams Chat Recording with Webhook/DLP API

The configuration steps for the Webhook/DLP API can be found here:

Configuring the Verba Unified IM Recorder Service for Microsoft Teams Chat Recording

Configuring Microsoft Teams Chat Recording with Export API

The configuration steps for the Export API can be found here:

Configuring the Verba Unified IM Recorder Service for Microsoft Teams Chat Recording with Export API

Configuring Separated Recording Director and Media Recorder roles

In the case of the Webhook/DLP API, it is possible to separate the Recording Server roles. 

The following configuration steps need to be done when the Recording Director and the Media Recorder roles are separated:

Step 1 - Configuring the Verba Unified IM Recorder Service on the Recording Director Servers

Step 2 - Configuring the Verba Unified IM Recorder Service on the Media Recorder Servers
