IP telephony: technical specification

DEAC in collaboration with telecommunication service providers ensures VoIP solution by using SIP (Session Initiation Protocol) trunking, which replaces the need for traditional analog, T1-based Public Switched Telephone Network (PSTN) gateways and their attendant cost and complexity. PSTN network architecture has developed significantly over the past years as number of users, connections and calls have increased. Worldwide PSTN telephone networks are now almost digital and include not just fixed phones, but also mobile and other networks. Unified PSTN standards ensure seamless interconnections between various networks in different countries all over the world.

It is a direct connection between your organization and DEAC and it enables you to extend voice over IP (VoIP) telephony without the need for an IP-PSTN gateway.
