GoTrunk Features

Go Trunk is a SIP trunking service that delivers a cost-effective, reliable and feature rich communications platform for businesses that operate their own PBX. It provides inbound telephone numbers and connects your outgoing calls to the PSTN (public switched telephone network). Go Trunk gives businesses powerful communications features, agility, reliability and low-costs.

Free Internet calls

Free Internet calls

GoTrunk provides free calls between all your SIP endpoints, which means your people can talk to each other for free no matter where in the world they are located. Everyone in the organization is easily within reach at no cost – helping you to improve communications and save money.

Reduced call rates

One second billing

Some telecoms providers round up your call time to the nearest minute. We never do that. We charge per second, so you only ever pay for the call time you actually use. And with GoTrunk there’s no call setup fee either – another big saving compared to many providers.

Hosted phone system

No contract

We don’t believe in tying our customers down with long term contracts. Instead, we rely on quality of service, reliability and exceptional value as ways of retaining our customers. We want you to be 100% satisfied, and if you are not, then you are free to leave at any time.

Virtual numbers

Disaster recovery options

Ensuring business continuity is vital for organizations large and small. Because your calls are routed over the Internet, your people are never tied to one location. GoTrunk operates out of the three data centres in the UK, US and Japan.

Web portal

Hybrid VoIP solution

Some business can benefit from SIP trunking for major premises and Cloud PBX in smaller offices or for home workers. Use both through one unified account with GoTrunk and our sister service VoIPstudio.

Multipoint registration

Quality Control

GoTrunk offers the highest quality SIP trunking – engineered to be the best. But don’t take our word for it: easily monitor call quality in real-time for peace of mind and reassurance that your business communications are in good hands.
