SIP Trunking is potentially suitable for any size of business that currently has a PBX connected to the Public Switched Telephone Network (PSTN). With SIP Trunking you can get a service that is more robust and cost effective than ISDN - and because it is an IP based telephony service, you also get a whole host of added benefits that can solve real business issues.
When to consider SIP Trunking:
Moving Premises ♦ Disaster Recovery ♦ Reducing Call Costs ♦ Local Presence ♦ Site Consolidation

- Benefiting from SIP
Reduce costs: Enjoy cost savings by reducing the operating expenses of managing your network connectivity, enjoy free calls between your offices and lower call costs beyond the enterprise.
Only pay for capacity you need: Calls are only limited by bandwidth availability, allowing you to easily adjust capacity in line with changing business needs - without the need for additional lines and PBX interface cards.
Increase resilience: Eliminate dependency on individual circuits. Should a circuit fail, calls can be redirected in a matter of seconds - no need for re-provisioning or complex call forwarding services.
Number flexibility: Retain your existing business identity by keeping the same geographic telephone number, regardless of where you may physically move – and without any ongoing call forwarding costs and costs associated with new company stationery.
Accelerate ROI: SIP Trunking can significantly improve the return on your IP Telephony and your IP Networking investment.
Accelerate future deployments: More than just telephony - SIP Trunking is just one major element of the transition to IP communications and platforms for UC, services, and applications.
How does it all work? (The techy bit)
Session Initiation Protocol (SIP) has emerged as the universal blueprint for IP Telephony and Unified Communications. SIP Trunking provides direct access to and from an Internet Telephony Service Provider (ITSP), with the ITSP providing the gateway connection between the enterprise's PBX and the Public Switched Telephone Network (PSTN) using the SIP VoIP standard. As a logical rather than a physical connection, SIP Trunking benefits from having virtually no limit on the number of concurrent calls carried over a single trunk other than the available bandwidth.
