The MiVoice Office Call Recorder provides an IP/SIP Extension recording source that provides recording for MiNET handsets and generic SIP base devices (including Phone Manager Desktop and Mobile softphones).

This method of recording calls uses a network port mirror to capture the call audio. It can scale a lot larger than the Record-A-Call recording source and is the only way to record calls made on SIP based extensions.

To configure an MCS server to record this IP/SIP traffic, the following must be configured:

• A mirror port must be made available on the customer's network switch which provides a copy of data from the telephone system's network interface.
• A spare NIC must be made available on the MCS server to plugin the mirror port into.

Any RTP audio and SIP traffic that gets passed to the MCS down the mirror port can be recorded.

Once the mirror port(s) have been plugged into the MCS server, the following configuration must be completed to begin recording:

• Navigate to the Mirror Ports section of the website and tell the MCS which network cards on the server are providing the RTP/SIP data to record.
• Navigate to the Packet Filters section of the website and tell the MCS about the ports on which the RTP/SIP traffic can be found.
• Navigate to the Addresses section of the website and enter the IP address(es) of the telephone system.
• Add the devices to be recorded under the Recorded Devices section of the website.

PS-1 & Multiple PBXs

It may be necessary to port mirror multiple network connections in order for the MCS server to receive all the required information.

If a MiVoice Office 250 has a PS-1 server installed then the network connections for both the Base Server and the PS-1 server need to be mirrored to the MCS.

If the MCS is recording calls for extensions on more than one PBX then each PBX's network connection(s) needs to be mirrored to the MCS on a single mirror port. 

Remote IP/SIP Extensions

Remote extensions (extensions that are not on the same LAN segment as the telephone system) can be recorded by the MCS server using IP/SIP Extension recording, but only in certain circumstances.

Remote SIP Extensions

SIP Extensions can always be recorded using the IP/SIP Extension recording source, no matter where they are located.The MCS interprets the SIP traffic between the telephone system and the extension to identify the extension involved in the telephone call. This is true even for SIP extensions that are connecting through a MiVoice border Gateway.

This applies to Phone Manager Softphones, both desktop and Mobile.

Remote IP Extensions (NAT'd through a firewall/router or Proxied through a MiVoice Border Gateway)

IP extensions that are connecting through a firewall/router or MiVBG can be recorded as long as each extension has a unique IP Address that can be seen by the MCS server. If there are multiple IP extensions connecting from the same remote location, the MCS server will only be able to see a single IP Address and will not be able to tell the extensions apart.
