A SIP trunk is used to make and receive phone calls using the internet instead of using traditional copper phone lines. Think of it like a virtual phone line that connects your phone system to the internet and therefore to the national and international phone network.
Traditionally, when you made a phone call, your voice would travel through physical copper phone lines. With SIP trunks, your voice is converted into data packets and transmitted over the internet. This means you can make and receive calls using your internet connection instead of relying on a physical phone line.
SIP stands for Session Initiation Protocol. SIP is the protocol that enables various forms of real-time communication, such as voice and video calls, to occur over the internet by handling the setup, modification, and termination of these communication sessions.
At the heart of every 3CX VoIP system is a SIP trunk. They are the virtual phone lines that connect your 3CX system to the outside world.
That’s why it makes sense to choose a provider with SIP trunks optimised to deliver a high level of performance within your VoIP setup.
Not all 3CX providers have their own SIP trunks, and we were concerned that our customers’ systems wouldn’t get an appropriate level of support from third-party infrastructure. So we set up our own service, and engineered it to provide the highest levels of reliability. When you connect your cloud hosted or on-premise PBX to a UFONE SIP trunk, your business will enjoy a higher level of resilience.
Designed from the ground up to be ‘carrier grade’
Not all SIP trunks are equal. UFONE’s core SIP infrastructure uses a purpose-built mesh architecture that allows any of its nodes to failover to any other node for continuity of service in the most testing of circumstances.
We take responsibility for reliability
Matching our SIP trunks with our phone service ensures the highest level of reliability, as well as quality of service. With end-to-end visibility and control over the network, we have the power to move fast if a fault appears. Another bonus: there’s virtually no latency between our equipment because it’s on the same core architecture.
We’ve got your number
UFONE makes it easy for you or your IT service provider to set up a VoIP system with our SIP optimised trunks. We provide our own number ranges in New Zealand, or you can port your number from another provider to us. Everything will work smoothly together, because that’s our mission in life.
Trusted by independent 3CX certifiers
Because we have full visibility and control of the entire 3CX solution, we monitor and maintain the network proactively. UFONE’s SIP trunks are regularly subjected to rigorous performance and functionality checks by both 3CX and our engineers, so you can be sure they’ll deliver. That’s what makes us a 3CX Preferred SIP Provider.
