Frequently Asked Questions

SIP Trunking, put simply, is a means of operating phone systems over the internet, instead of using a traditional phone line. Learn more about how SIP trunking can transform your business communications on our Resource Center.

One SIP trunk is all your business needs to run all of your communications. Once your trunk is set up, you can scale up or down concurrent call capacity by adding or removing usage channels, or choose pay-per-minute billing for unlimited concurrent inbound call capacity.

SIP trunking is cheaper than traditional business phone systems. We offer pay-as-you-go pricing with automatic volume discounts as you scale. Find out more with an in-depth breakdown of our pricing, or talk to an expert to get a custom quote.

SIP Trunking has a huge range of benefits over traditional business telephony systems, including scalability, cost savings and configurability. Find out more about what SIP trunking can do for you on our Resource Center.
