Solution Overview
The QMS Call Recording Service supports two general methods of recording calls for NEC. The first method of recording is accomplished through the use of port mirroring to collect call control messages (SIP or PROTIMS over IP) and RTP traffic. The second method of recording uses NEC OAI library to collect call control messages from NEC PBX. Audio is sent from each NEC phone to QMS Call Recording Service directly. This method requires phones with Built-in-bridge support.
Port Mirror Solution
The port mirroring solution allows QMS Call Recording Service to collect call control and audio packets that traverse across the data network. Port mirroring is supported by most data switches and when enabled will send a copy of every packets destined for one port to another port. For more information about port mirroring, please refer to "Port Mirroring Configuration Guide".
