What is SIP trunking?

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.

How many SIP trunks do I need?

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.

How much does SIP trunking cost?

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.

What are the benefits of SIP trunking?

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.

How can I get started with SIP trunking?

Getting set up couldn't be easier. Just sign up for an account, then follow one of our Bring Your Own Carrier guides to integrate with your PBX or softphone client.

How do I configure SIP trunks?

You can configure, monitor and manage your SIP trunks through the Telnyx Mission Control Portal. For large-scale or automated configuration, you can also leverage the Telnyx API to configure your communications programmatically.
