At ECTtelecom.com our business customers are switching from TDM Long Distance to SIP Trunking. Many of our SIP Trunking customers are also finding a solution of cutting costs by utilizing SIP over Internet Protocol (VoIP) on their mobile phones.
Is it necessary to implement Dedicated Access for SIP trunks? Yes – All service providers offer T1, Bonded T1, T3 (DS3), OC3 and OC12 to support SIP Trunks. Some businesses are using Ethernet at layer 2 and business class DSL or Cable, however your connectivity and quality of service is better with Dedicated Access.
Basic telephone service has bundles of wires delivered from the service provider to a business, whereas SIP trunk allows the business to replace these phone lines (PSTN) with PSTN connectivity via a SIP Trunking service provider. SIP trunks offers significant savings by eliminating local PSTN, ISDN or PRI’s.
