Delivery

TDM Delivery

Trunk Delivery (line-side recording using E1 trunks) is a type of trunk termination that can be implemented in Avaya switches and is supported on ISDN trunks (DT6409 and DT3209 cards only).

E1 line-side (E1 LS) is a recording method in which the Recorder uses service observe in to control extensions (supported in Avaya switches). It maps each of its recording channels to one of the E1 trunk time slots and to specific employee extensions. When an employee logs in to the switch, the Recorder establishes silent observation for the extension on a recording channel, and from that moment on, the trunk delivers the extension's audio to the Recorder.

VoIP Delivery

VoIP Delivery is supported in SIP-based DMS for Cisco Call Manager, and Device and Media Call Control (DMCC)-driven DMS for Avaya, and certain Trading environments. (See the associated Integration Guide for solution-specific information.)

VoIP Delivery in DMCC Environments

DMCC is a software connector that provides a programming interface for device and media control on the Avaya Communication Manager switch. Using the DMCC, you can develop applications that can do the following:

Gain exclusive or shared control of extensions defined in the switch.
Perform telephone operations, such as silent observation.
Process or redirect media using RTP (VoIP), such as sending an extension's audio to a specific IP address.

Applications developed for DMCC communicate with the Avaya Communication Manager switch through the DMCC Connector interface. These applications send the DMCC Connector requests to take control of an extension defined in the switch, in order to perform telephone operations on these extensions. These operations can include making calls, receiving calls, sending announcements, applying tones, detecting digits and redirecting the extensions calls to a specific IP address.

The DMCC Connector sends the request to the switch and in effect creates a "soft phone" for the relevant extension (that is, a virtual phone that is controlled using an application rather than a physical telephone device). The DMCC Connector can instruct the switch where to direct the audio (in the format of RTP streams) for calls made to and from the extension. This feature enables the Recorder to record calls on these extensions.
