Often referred to as the imminent replacement for POTS lines, SIP Trunking connects your traditional phone lines through the Internet. SIP Trunking enables your business to reduce costs and simplify IT management by combining voice and Internet access over a single Internet connection using your existing IP PBX system.
With SIP service, you purchase only the trunks you need based on the maximum number of concurrent calls your business requires. SIP Trunks are significantly less expensive than analog lines, further helping businesses reduce costs.
- Creates a connection from a company’s phone system to the Internet, replacing the conventional public switched telephone network (PSTN).
- Is delivered by a service provider as an overlay service to existing broadband access (DSL, cable, T1/E1, Ethernet, etc.) or bundled with its IP network.
- Works with a SIP-ready PBX or with traditional analog systems by adding an integrated access device (IAD).
SIP Trunking reduces costs by:
- Eliminating dedicated circuits. SIP trunking eliminates the need for traditional analog and digital trunk facilities and allows communications to be routed over existing data connections.
- Consolidating PBX needs. SIP enables communications across the Internet as easy as the corporate LAN, so a multi-location business can use one centrally located IP PBX instead of installing separate ones at each site.
