A SIP trunking service can offer significant cost-savings to enterprises by allowing them to use very cost-effective SIP trunks in place of expensive PSTN trunks. Instead of the bundles of physical wires delivered from service providers to businesses in traditional telephony, a SIP trunk allows a company to replace traditional fixed PSTN lines with PSTN connectivity via an internet connection delivered by an Internet Telephony Service Provider (ITSP).
Dialogic® BorderNet™ Session Border Controllers can play a critical role in SIP trunking services. A BorderNet 2020 SBC can connect to the SS7/PSTN network and handle switching, signaling, and media processing in a single unit while relaying calls to a BorderNet 3000 SBC for classic session border control functions. A single 2020 SBC can handle thousands of calls per minute.
