How SIP Trunks work

SIP trunks are digital VoIP “lines” that significantly reduce call charges for businesses of any size whilst allowing complex routing options to maximise the efficiency of your phone system. For example, a US-based company might add some of our SIP trunk channels to their PBX to route all UK-bound calls through. Adding a SIP trunk route to your existing cloud-based or inhouse PBX system is really easy within your software (eg 3CX or Asterix).

 SIP Trunks
  • Take advantage of the best rates per destination country

  • Lower costs for both calls and system rental/lease over traditional systems like ISDN or PBX

  • Highly scalable at short notice

  • Resilience guaranteed by our geographically diverse network nodes

  • Consolidate whole phone system over multiple branches with one system to manage

  • Highly versatile with unlimited configuration and routing options

International SIP

 SIP Trunks

Our SIP trunks are extremely popular for international companies who need high quality and low cost VoIP call routing for UK-based customers and branch offices. With low or no call charges and the ability to work with any PBX platform – all we need is an IP to confirm the SIP routing on our platform – businesses all over the World can enjoy trouble-free VoIP calls to the UK, including UK mobiles. Perfect for any size business or call center.

What is a SIP trunk?

A SIP trunk is like a virtual telephone line that you can connect your SIP-compatible phone system to in order for it to make and receive calls. Similar to traditional ISDN channels – the number of SIP trunks you have determine the total simultaneous calls on your system

Can I use the SIP trunk outside of the UK

Yes, our SIP trunks are very good options to add low-cost call routing for non-UK based companies on their VOIP system.

What’s the contract term?

Unlimited Trunks are subject to a 1 year contract, other SIP trunks are 30 day rolling terms. A valid automatic payment method is required to cover call costs (credit card or DD or invoice subject to approval)

Do your SIP trunks work with 3cx, Asterix etc?

Yes, our SIP trunks work with all PBX and phone systems. We also offer expert 3cx hosted systems, handset and advice.
