Recorder control types

The recorder control type determines what method will be used to record extensions assigned to a given member group, and a given deployment can be a mix of any or all of the Control Types in this section.

There are seven recorder control types. The two main deployment types are CTI Controlled and Recorder Controlled. Recorder Control types apply to member groups, which define phone extensions associated with trunk groups (spans), station-side extension groups, and IP extension pools (IP only).

CTI Controlled deployments are those in which the Integration Service tells the Recorder when to start and stop recording. If you are using Avaya DMCC, use this setting (see the Avaya Integration Guide for more details).
Recorder Controlled deployments are those in which the Recorders themselves control recording, and the Integration Service is used for segmentation, stitching, and tagging purposes. In the context of an IP Recorder, recording is accomplished by a means of decoding of IP control packets, such as Skinny or SIP. In the context of a TDM Recorder, recording control is accomplished through either D-Channel detect, VOX, CAS, or line voltage (tap sense) recording, and the Integration Service provides tagging information from CTI events. If you are using IP Analyzer, use Recorder Controlled.

During a Pause, nothing is recorded. Similarly, use of the Exec Delete button will override recording according to the Delete/Block Behavior setting.
Use Selective Delivery (Duplicate Streamed) in selective delivery recording. Specifically, in environments where the Recorder Integration Service issues requests to start recording to a third-party application. The Duplicate Stream recorder control type is available for Avaya DMCC, Avaya NES DMS, Cisco Call Recording, Twilio Flex, and SIPREC recording.
Use Full Delivery (External Controlled) in compliance delivery recording. Recording is controlled by a 3rd party application, which redirects audio to the Recorder. The Full delivery recorder control type is available for Cisco DMS (where the Recording Option of the line has been set to Automatic Call Recording), Genesys SIP full Delivery, and Zoom Contact Center.
The Service Observe recorder control type is available when using an Avaya or Generic switch type to support configurations in which the recorder analyzes call control messages and then uses the Service Observe functionality of the switch to record the call. Service Observe allows a specified user, such as a supervisor, to observe or monitor another user’s calls. Use this control type in conjunction with a Trunk Span Recording Resource or Extension Recording Resource member group. For Avaya DMCC, use either this or Single Step Conference as the recorder control type.
The Single Step Conference recorder control type is available when using Avaya, Alcatel, and Generic switch types. Single step conferencing is used to connect an in-progress call to a device. Use this control type in conjunction with a Trunk Span Recording Resource or Extension Recording Resource member group. For Avaya DMCC, use either this or Service Observe as the recorder control type.
The Multiple Registration Control type is the default recorder control type for Multiple Registration Extension Pools, used in Avaya DMCC environments to support multiple device registration (including support for N+N redundancy).

In Avaya DMCC, the member groups are a combination of an Extension Recording Resource (for which you must select either the Service Observe or Single Step Conference recorder control type), and either a Selective or Dedicated Extension Pool (for which there is no recorder control type to select).
