Telrex Announces CallRex™ Release 3.5 Delivering New Capabilities For Business-Class VoIP Call Recording and Monitoring

KIRKLAND, WA – January 22, 2007 – Telrex, developer of VoIP call recording and monitoring software for businesses using IP PBXs or hosted VoIP services, today announced the release of CallRex Call Recording 3.5 featuring an advanced distributed-services software architecture. CallRex 3.5 delivers greater scalability, high reliability and additional security, plus new features for multi-site deployments including enhanced multi-site call recording and monitoring, advanced file transfers, flexible storage and streamlined archiving. CallRex was the first VoIP call recording solution verified to record encrypted VoIP calls for Cisco CallManager 5.0, and CallRex version 3.5 now provides additional security to ensure that call recording files cannot be secretly altered.

Distributed-Services Software Architecture

The innovative CallRex 3.5 distributed-services software architecture features separate services for status, control, recording and conversion of VoIP phone calls. CallRex 3.5 services operate independently and are deployed on industry-standard Windows servers in single- or multi-server configurations. Together, the CallRex 3.5 services enable the recording, monitoring, retrieval, playback and utilization of call recordings from any location. This next-generation design provides high reliability and enables virtually unlimited scalability across multiple servers and multiple office locations.

"The CallRex 3.5 platform gives us the enterprise scalability that our growing company requires," says Jay Whalen, Manager of I.T. Infrastructure at Global Forex Trading (GFT), a world-leading provider of real-time currency and equity derivatives services for retail and institutional traders, "With CallRex 3.5, we have a great deal of flexibility in how we deploy and manage CallRex for our worldwide office locations and remote users."

Enhanced Multi-Site Support

Businesses and call centers with multiple office locations benefit from the enhanced multi-site support of CallRex 3.5. In addition to providing full-time and automatically triggered call recording, CallRex 3.5 enables on-demand recording and real-time monitoring of employees’ phone calls from any location across the entire organization. Through the CallRex 3.5 user interface, authorized individuals are presented with the real-time status of every licensed IP phone on the system. Supervisors and managers are able to selectively monitor and record designated users regardless of their location.

CallRex can be physically deployed across multiple sites or located centrally depending upon customers’ infrastructure requirements. CallRex software is licensed on a per user basis resulting in no additional software costs to deploy multiple servers. CallRex 3.5 is managed as a single virtual system from any location providing for ease of administration.

Streamlined Storage and Archiving

CallRex 3.5 provides multiple options for storing recorded calls, and delivers enhanced archiving features to streamline management and administration. With CallRex 3.5, call recordings can be stored on a centralized server, stored locally across multiple servers, or stored directly on Network Attached Storage (NAS) or on a Storage Area Network (SAN).

Advanced file transfer options enable call recording files to be transferred automatically in real-time, or transferred in batch at off-peak times for efficient network bandwidth utilization. Batch transfers can be initiated automatically according to flexible predefined schedules set globally or on a per-server basis. As call recordings are transferred from primary storage to archived storage, CallRex 3.5 enables the automatic tracking of files across multiple locations over time, ensuring ready access to call recordings.

Additional Security

CallRex is the first IP-based call recording and monitoring solution verified to record encrypted VoIP calls with Cisco Unified CallManager 5.0. Previously, companies deploying VoIP call recording solutions were forced to disable call encryption in order to record their calls. Now with CallRex, companies can both record their calls and maintain secure call encryption to meet stringent security, legal and regulatory requirements. Telrex is a partner in the Cisco Technology Developer Program and has met the interoperability criteria for Cisco Unified CallManager version 5.0.

CallRex 3.5 delivers digital watermarking security to ensure that call recordings, once created, cannot be secretly altered or edited. For each recorded call, CallRex digital watermarking generates a unique signature associated with the data file. Any change made to a call recording disrupts its watermark indicating that tampering has occurred. Authorized users are able to validate the watermark at any time. CallRex digital watermarking provides additional security, enhances audit-trail integrity and raises the standards for legal and regulatory compliance.

"CallRex 3.5 represents a significant advancement in the architecture and capabilities of the CallRex platform," said Bob Cordes, VP Product Management and Marketing at Telrex, "As call recording and monitoring continues to gain acceptance as a standard business application for dispute resolution, regulatory compliance and training purposes, Telrex continues to set the standard for practical, affordable VoIP call recording."
