VoIP Call Recording and Monitoring

CallRex IP call recording and monitoring software uses packet sniffing technology to record and monitor calls without interfering with the IP telephony system. CallRex monitors VoIP packets via port mirroring on the data switch connected to the IP PBX. Every VoIP packet that goes to and from the IP PBX is copied to the CallRex Server, which then reassembles the packets into a recorded call and compresses and stores the recorded call for later retrieval.

CallRex Call Recording™ software has two components: the CallRex Server and the CallRex Client. The CallRex Server coordinates all recording and monitoring. Call recordings can be stored on the local server, transferred to a central server (for multi-server deployments) or stored on network attached storage (NAS) or on a storage area network (SAN).

CallRex Client

The CallRex Client is for managers, end-users, system administrators and others who monitor activity and configure who will be recorded and under which circumstances.

Based on assigned access rights, the CallRex Client enables adding users, retrieving calls, monitoring calls in real-time, and administering CallRex. View short online video demonstrations of the call recording interface.

All CallRex Client features are accessible through the CallRex API™, meaning CallRex call center optimization functionality can be integrated directly into other applications used by your organization.

Scalable Call Center Software Solution

CallRex Call Recording is designed to scale across multiple sites and thousands of users. CallRex Call Recording utilizes the WAN infrastructure to link a central CallRex Server with distributed CallRex Call Recording Servers, known as data collectors, deployed in remote sites.

Remote sites must have their own local dial tone and trunking.
