SIP (session initiation protocol) trunking is used for establishing a voice communication session on a data network, e.g. over the Internet. A SIP session could be a regular VoIP phone call between two participants or a multi-party conference call. A SIP trunk provides the same service as a traditional analogue phone line (except that it is a virtual phone line rather than a physical wire) and enables you to control costs efficiently with consolidated voice services on a SIP-based VoIP network.
How does our SIP service work?
A data connection (the Internet) and a SIP trunk (your voice) runs between your business and our data and SIP network, with Paradyn providing a connection to your phone.
Connections are virtual, so the number of available trunks is determined by your company’s bandwidth and not physical hardware or circuits.
Benefits of SIP telephony
• Upscaling can usually be performed as easily and quickly as a software configuration change and can offer automatic burst capabilities.
• Automatic IP rerouting capabilities allow for practical geographic distribution of PSTN connectivity to sites without affecting the operation of the network.
• SIP trunking costs are generally lower than the alternative of PRI (primary rate interface), relative to circuits and associated hardware.
• SIP trunking allows for automatic call rerouting to predefined locations in the event of the location going offline. Call diversity can easily be accommodated across multiple locations.
