About Mitel SRC recording

The Secure Recording Connector (SRC) service is a software solution that facilitates the recording of encrypted Mitel call/voice streams by a third-party call recording equipment (CRE). The
Mitel Border Gateway (MBG) server with SRC service is positioned on the LAN between the Mitel IP Communications Platform (ICP) and recorded telephone sets .

Mitel IP Communications Platform (ICP) also known as MiVB (Mi Voice Business). SRC accepts requests from an authorized call recorders to establish taps for recorded voice streams. These taps are separate (mirrored) streams from the SRC to the call recording equipment (CRE).

Gallery: VSLogger - HW MISRC SRC Recording

The SRC allows a Call Recording Equipment (CRE) to record calls in one of the following modes:

Direct Call Recording
Indirect Call Recording

Direct Call Recording

With direct call recording, the MBG server is positioned between the call server and the devices/trunks handling both signaling and media. This allows MBG to send copy of select media streams to the recorder(CRE) on request.

Direct call recording is supported on:

Any MiNET MiVoice IP phones or softphones connected with MBG in a MiVoice Business deployment
Any SIP device registered with MBG
Any SIP trunk using MBG as an outbound proxy

Note:

Local streaming will not take effect if a CRE is connected to MBG
An SRC license is required for each recorded call for each CRE request
A transcoding license is required if the CRE requests the recorded audio to be sent using a specific codec (ex: G.711U)
Internal MiNET phones can be pointed at MBG instead of MiVoice Business either automatically using DHCP or manually using the Teleworker setting.

Deployments

Direct call recording is supported in all MBG deployment in any network profile.

To record internal devices, setup a MBG in a LAN network profile.

To record both internal and teleworker devices, setup one of the following configuration:

An MBG on the LAN to handle internal devices and an MBG on the edge to handle teleworker devices. The CRE must make a connection to each MBG.
(MiNET only) An MBG on the LAN to handle internal devices and an MBG on the edge to handle teleworker devices. The edge MBG is configured in a daisy-chain pointing teleworker devices to the LAN MBG. The CRE makes a single connection to the LAN MBG.
MBG on the edge handling both internal and teleworker devices. All devices must be configured to use the external interface of MBG. This configuration requires additional bandwidth and teleworker licenses for all devices unless network routing allows internal devices to reach MBG's external interface via MBG's internal interface. The CRE makes a connection to the edge MBG.

Selecting Sets to Record

Internal MiNET phones can be pointed at MBG instead of MiVoice Business either automatically using DHCP or manually using the Teleworker setting.

To record…	You can use this DHCP setup…
A small percentage of total sets	Configure the phones manually as teleworker phones and enter the IP address of the MBG/SRC server when prompted for the Teleworker Gateway IP address. For more information, refer to the MBG Remote Phone Configuration Guide available at Mitel OnLine.
A large percentage of total sets	A possible setup for this scenario is to deploy the recorded group on a different subnet from the non-recorded phones. You can use the MiVoice Business/3300 ICP as the DHCP server for the non-recorded phones and the MSL server as the DHCP server for the recorded phones subnet. The recorded phones will then receive the IP address of the MBG/SRC server as their Call Server (ICP) and TFTP addresses.
All sets	Configure the DHCP server in your MiVoice Business/3300 ICP to supply the IP address of the MBG/SRC server to the phones as their ICP and TFTP addresses OR Enable the pre-configured DHCP server supplied with the MSL server.

For more information about configuring DHCP in the MSL server, refer to the Configuring the Server section of the Mitel Standard Linux Installation and Administration Guide.

Recording Teleworker Sets

With Direct Call Recording, the Secure Recording Connector (SRC) service of the MBG server can establish voice stream taps for IP sets located on the LAN and for teleworker sets located on the external network. Both voice and signaling streams pass through the SRC.

You can enable direct call recording on a global basis for all sets, or on a "per set" basis for particular MAC addresses.

Enable Global Call Recording

To enable global call recording:

On the MBG main page, click the Teleworking tab and click Application integration.
In the Call Recording frame, select the Enabled box.
To inject tone into calls, select the Tone Injection Enabledbox.
Click Save.
Click the System tab and click Settings.
Under MiNet options, clear Local streaming.
Under SIP options, clear Local streaming.
Click Save.

Configure SRC Port Ranges (Optional)

To configure the Secure Recording Connector (SRC) port ranges on MBG:

On the MBG main page, click the Network tab and click Port ranges.
If required, update the SRC starting port and SRC ending port numbers.

After completing the configuration, double-check all settings. They are critical to the operation of the WebRTC gateway and are included in the Software Development Kit (SDK) that you download for deployment to your web server.

Local Streaming for Teleworker Sets

If both Local Streaming and Call Recording are enabled globally, and a CRE (Call Recording Equipment) is connected to the MBG server, the Call Recording option takes precedence. Local streaming would not take effect even if it is configured.

Indirect Call Recording

With indirect call recording, the remote devices are registered directly to MiVoice Business instead of the MBG. MBG acts as a broker between the call recorder, platform and devices. The device duplicates its audio stream and sends it to the CRE.

Indirect call recording is only supported on:

MiNET 5300-series and 6900-series MiVoice IP Phones
MiVoice Business release 5.0 SP1 or later
Any MiNET device registered with any MBG. MBG adds Indirect Recording capability for all connected MiNET devices. This is primarily used to support Indirect Recording for teleworker sets.

Note:

Recording tones cannot be injected by either the CRE or MBG
A maximum of 3 CREs can request to record a given call
The CRE might impose codec restrictions in the deployment of MiVoice Business

Deployments

For Indirect recording, use a LAN-based SRC with no sets connected to give the CRE access to all the sets that are connected to the MiVB. You can, however, use any MBG to gain this capability so an existing deployed MBG (for Teleworker) can also be used for indirect call recording.

Recording Sets (Indirect Call Recording)

The Indirect Call Recording feature facilitates centralized call recording of IP sets connected to ICPs located in remote offices.

Once this feature is implemented, the Secure Recording Connector (SRC) service of the MBG server acts as a broker between the ICPs and third-party CREs for adding and removing taps on the IP sets. The ICPs send copies of the signaling to the MBG/SRC while the IP sets send copies of the RTP media streams to the CREs.

Indirect call recording is supported on:

5300-series and 6900-series MiVoice IP Phones using the MiNet protocol
ICPs with MiVoice Business release 5.0 SP1 or later
a limited range of Call Recording Equipment. The 53xx and 69xx sets support different SRTP crypto suites. The 69xx sets no longer support the legacy SRTP cipher suite so Indirect Call Recording of 69xx sets requires the call recording vendor to support the newer SRTP ciphers available in the latest (version 1.6) SRC interface on MBG. Contact Mitel Technical Support for a list of supported equipment.

Note: The 53xx sets support both the legacy and newer SRTP ciphers so if your deployment includes a mix of both, you must use a CRE that supports the newer SRC interface. This does not affect Direct Call Recording.

Enable Indirect Call Recording

To enable indirect call recording:

On the MBG main page, click the Network tab and click ICPs.
Click to add a new ICP or to edit an exiting ICP.
Select Indirect call recording capable and other ICP settings, and then click Save.
On the MBG main page, click the Teleworking tab and click Application integration.
In the Call Recording frame, select the Enabled box and click Save

Configure Mitel OIG in VSLogger Application

SRC service does not provide Call Details for recorded calls. Mitel Open Integration Gateway (OIG) is required to collect and apply call details (Call direction, Caller ID/Dialed) to the recordings.

Communication session between Versadial VSLogger and OIG have to be established to enable VSLogger application to receive recorded call details Mitel OIG server.

Note: Mitel OIG Licenses (Standard Call Control or Advanced Call Control) are required.
