Version 3 of Telrex's CallRex software includes new features including look-back call recording, support for Citrix terminal services, the ability to export multiple calls, improved trigger filtering, automatic deletion of recorded calls according to pre-defined criteria, remote polling of recorded phone calls, improved recording quality, re-start capability for remote data collectors, improved call compression, improved record-on-demand capabilities, and the ability to automatically receive software updates online.

"CallRex is entirely software based, thus it is 50-60 percent less expensive than legacy-based solutions that require expensive proprietary telephony cards and are complex to install," said Robert Kapela of Telrex.

CallRex works with numerous IP PBXs, currently supporting 3Com, Mitel, Avaya, Cisco, Shortel, Nortel, Siemens, NEC, Zulty, Artisoft, and many softswitches and gateways.

Telrex provides workplace recording and monitoring software.
