SIP Trunks

A SIP (Session Initiation Protocol) trunk is a service that allows businesses with an installed PBX to use real-time communications including VoIP. By connecting an SIP trunk to an internal traditional PSTN (public switched telephone network) phone system, companies can communicate over IP outside the enterprise. What’s more, companies can replace traditional fixed PSTN lines with an IP phone system connected externally through an SIP-trunking service, thereby creating a single conduit for multimedia components including voice, video and data. As a result, an SIP-trunking service typically delivers greater cost savings and increased reliability.

I-Net Solution SIP trunking blends connections for both data and voice into a single line. By serving as a converter between a legacy phone system and a company’s Internet connection, an I-Net Solutions' SIP-trunking allows the data network to carry voice traffic. SIP-trunking features typically include local and long-distance calling, E911, directory listing and caller ID, all of which integrate into a company’s existing phone system.

I-Net Solution' SIP-trunking service benefits companies by:

    •    Eliminating the need to invest in costly (and less capable) TDM-gateway equipment infrastructure or desktop equipment

    •    Nullifying the need to purchase equipment, such as managed-media gateway devices, to interface between IP voice and the PSTN

    •    Reducing monthly expenses, since only one connection for data and voice is needed

    •    Eliminating the need for PRI (primary rate interface)/BRI (basic rate interface) connections, lowering telephony costs

    •    Allowing companies to outsource their PSTN connectivity to a third party, reducing long-distance charges

    •    Providing points of presence in multiple U.S. cities so that companies can establish local numbers rather than rely on a 1-800 number

    •    Accessing the benefits of a hosted VoIP service, without discarding existing investments in a traditional phone system
