Telrex announces that the CallRex Professional call recording and monitoring solution has earned the designation of “Digium|Asterisk Certified” for Asterisk Business Edition. CallRex software from Telrex, an affordable, robust call recording software for Asterisk installations, was thoroughly tested in Digium’s lab to validate its interoperability with Asterisk Business Edition. Telrex is a Digium Interoperability Partner.

Digium is the creator and driving force behind Asterisk, the open source voice communications software deployed by more than four million servers worldwide to manage VoIP calls for businesses and individuals. More resellers, telecom professionals and software developers choose Digium's products than those of any other open source telephony company because only Digium delivers the technical superiority, security and flexibility associated with Asterisk. Asterisk powers Digium’s family of software and hardware appliances including AsteriskNOW, Asterisk Business Edition and Switchvox.

Telrex offers affordable call recording and monitoring solutions for small- to medium-sized businesses. Flexible, monthly “pay-as-you-grow” subscription pricing is available from Telrex so that companies can simply pay a monthly fee for the number of users being recorded.
