Mirror Ports

Overview

The port mirroring network adapters that the system needs to use to receive the RTP traffic on for recording IP devices is configured from this section. The list of available network adapters is shown and allows the administrator to select the required one.

The system needs to be able to receive all the RTP traffic that is sent and received from each device that is to be recorded. The easiest way to do this is to have the network connection that the PBX is connected to mirrored and any peer-to-peer media disabled as this will then ensure that all the RTP traffic flows through this connection.

As the network topology of each site can be different this may not be possible. It may be necessary to mirror multiple sources into one mirror port for connection to the MCS server mirror port for complete coverage of the RTP traffic.

Not all network hardware, i.e. switches, supports configuring a mirror port. Check your hardware manufacturers specifications to ensure the are compatible.

Configuration

To configure a mirror port:

Access the Servers Settings -> SERVERNAME -> Recording -> Recording Sources -> RTP/SIP Interfaces -> Mirror Ports configuration section.
From the list of adapters displayed check the one that needs to be used. The Name, IP Address, MAC Address and Interface name are provided for each adapter to help identify the correct one to use.
Click Save.
Restart the Call Logging Service.

Ensure that IPv4 & IPv6 protocols are removed from the interface selected for port mirroring. This will stop it getting an IP address and effecting other services on the system.

A restart of the Call Logging service is required after changing these settings.
