Today most businesses operate standard PBX or key systems supplemented by trunk side access services purchased from traditional telephony providers (also known as TDM trunking). T1, PRI, BRI and analog lines typically handle voice traffic to and from the PSTN.
SIP Trunking allows businesses to 'virtually' connect an IP PBX directly to the PSTN. As a result the enterprise no longer needs traditional PSTN circuits and this one IP “pipe” also can handle any communication needs including IP telephony (VoIP) to the PSTN, enterprise interoffice voice communication, and data and Internet traffic.
What you will learn from this Whitepaper:
SIP Trunking helps organizations to consolidate their voice and data traffic onto a single transport from a single provider. This paper is designed to help IT professionals and telecom managers learn more about this technology and its benefits and design alternatives, so you can make an informed decision on the benefits to moving to SIP Trunking.
