A unique, Linux-based platform supports a variety of location sizes, regional requirements and technology infrastructures in both legacy telephony and VoIP/SIP environments. Uniquely set apart from other typical unified messaging solutions, the T3 is a platform-independent application that shares resources and ports across all application components. Voice, fax, interactive voice response (IVR) and announcer capabilities use any available port, mitigating costs and administration complexities. T3main also utilizes tenanting and networking to integrate across multiple PBXs, email servers, database applications, and voice channels (T1, analog, VoIP).
