how it works

How SIP Trunking works

A SIP trunk is the virtual implementation of an analogue phone line. If you have an on-premises PBX in your office (or hosted virtually), by leveraging our SIP Trunking service, we can connect one, two, or twenty channels to your PBX, allowing you to make and receive local, long distance, and international calls. SIP trunks also make it easy to upgrade to a higher plan at any time. You can add more concurrent calls (also known as SIP channels) and phone numbers in real-time.

SIP Services that are delivered via ONQ Internet or Private IP services, don’t traverse the Internet. As the traffic doesn’t leave our network, we’re able to ensure QoS (Quality of Service) end to end, resulting in crystal clear calling and security.
