Thanks to its architecture, the t-Mailer™ can interface any existing mobile or fixed telephony network via multiple E1 connections (SS7 or PRI Signalling) or a VoIP soft-switch via SIP / MGCP protocols. The unique system architecture, shown in drawing No.1, is composed of two main logical components: CTI servers and backend servers.

CTI Servers are a scalable high performance telephony-processing unit handling incoming trunks and signalling traffic from the network and managing the XML script layer controlling the application call flow and IVR menus. Each CTI server is an independent unit interfacing a telephony network via an SS7, PRI, SIP or MEGACO interface while accessing the t-Mailer™ database for information retrieval or storage via the LAN.

The CTI servers provide a scalable solution for system growth and expansion. Since each CTI is completely independent of other CTI servers, a single t-Mailer platform may serve simultaneously several networks, each using different technologies. The entire t-Mailer™ is engineered to support N+1 redundancy for all CTI servers, thus a failed server will not cause service degradation or affect the operation of the whole system.

Backend Servers contain the main database supporting the CTI servers with the user data required to manage every incoming call. In addition, the backend units manage message storage, delivery and notification procedures, domain management, operation staff system accounts and more.
