Configuring Polycom RMX for conference recording

Overview

Verba Dial-in Recorder service is able to record video conference calls automatically via recorder link interface. For this to work, the Verba recorder must be provisioned via RMX configuration.

Supported call scenarios

This solution supports the following scenarios:

• all Polycom "conference room" calls on RMX bridge
• the recorded "conferences rooms" can be joined with H.323 and SIP both unencrypted and encrypted modes
• peer-to-peer calls are not forced to go through the RMX bridge, therefore peer-to-peer calls are not recorded in this scenario

Verba configuration steps

Please follow the configuration steps in Configuring Verba for SIPREC recording.

Configuration steps

Step 1 - Create  Recorder link

To define a Recording Link: in the RMX Management pane, click Recording Links,
in the Recording Links list, click the New Recording Link button.

• 1. Select SIP as the controlling protocol

  2. Enter the IP address of the recorder

  3. Enter a SIP URI pointing to the recorder

Step 2 - Create/modify existing conference profile

To be able to record a conference, the recording options must be enabled in the

Conference Profile assigned to it. You can add recording to existing Profiles by modifying
them. In the RMX Management pane, click the Conference Profiles button.
Create a new profile by clicking the New Profile button or modify an existing profile
by double-clicking.

• 1. In Advanced menu set Encryption to Encrypt when possible
  2. In Advanced menu set Auto terminate when the last participant remains
     (recorder is threatened as normal participants from this point of view)
  3. In IVR menu on-demand recording DTMF codes can be changed
  4. In Recording select the recorder link, check enable recording
     and select recording start mode (immediately or upon request). You can also
     limit the recording line's bitrate

Step 3 - Assign profile for conferences

Assign the recording enabled profile to the conference rooms that need to be recorded.

Recording link encryption

According to Polycom documentation the recording link can be encrypted when recording an encrypted conference, this requires H.323 recorder signaling. Since Verba supports only SIP, the recording link cannot be encrypted, but still, it is possible to record an encrypted conference. To achieve this system flag ALLOW_NON_ENCRYPT_RECORDING_LINK_IN_ENCRYPT_CONF must be set to YES. Recording Link Encryption Flag Setting Recording Links are treated as regular participants, however, if the ALLOW_NON_ENCRYPT_RECORDING_LINK_IN_ENCRYPT_CONF System Flag is set to YES a non-encrypted Recording Link is to be allowed to connect to an encrypted conference.
