Cisco Unified Communications Manager Express - How-to record calls

Cisco 3800 Integrated Services Router

MiaRec supports call recording on Cisco Unified Communications Manager Express (CUCX).

MiaRec uses packet sniffing technology for call recording. It is necessary to configure port mirroring (port spanning) on the switch (see What is Port Mirroring?).

Configuration of port mirroring depends on what call types it is necessary to record: inbound/outbound calls or internal (local) calls between two local IP phones.

Requirements:

Record inbound and outbound calls only

In order to record calls, MiaRec should see the network traffic between IP Phones and Cisco Unified Communications Manager Express (PBX).

PBX port on the switch should be configured as a source for port mirroring session.

MiaRec port should be configured as a destination for port mirroring session.

Record inbound, outbound and internal calls

In order to internal record calls, MiaRec should see the network between IP Phones and Cisco Unified Communications Manager Express (PBX) as well as direct traffic between two IP Phones.

When internal call is made (between two IP Phones), the media (RTP) traffic is sent directly between two phones bypassing PBX. Because of this fact, it is necessary to mirror every phone's port rather than only PBX port.

Every phone's port on the switch should be configured as a source for port mirroring session.

MiaRec port should be configured as a destination for port mirroring session.
