As one of the UK’s leading SIP trunk providers, you can count on Infinitel to keep your business connected. Our SIP trunk service creates an IP connection between your PBX and our network, allowing voice calls to be made and received over the internet.


What is SIP trunking?

SIP trunking is a type of business phone system that allows businesses to make, receive, and transfer phone calls over the internet. SIP stands for Session Initiation Protocol and trunking refers to how all of your phone lines are connected.

SIP trunking provides cloud-based phone services for existing PBX phone systems. It allows businesses with legacy phone systems to access features that are only available on cloud-based phone systems.

The biggest advantage of SIP trunking for businesses is that multiple people can make calls at the same time. This will save you money in the long run, as you don’t need to add a new phone line every time someone joins the business.

The benefits of SIP Trunking

SIP trunking offers numerous benefits for businesses both big and small:

  • Cost savings: SIP trunking eliminates the need for traditional phone lines and reduces long-distance charges, significantly reducing business costs.
  • Scalability: Easily add or remove phone lines, allowing you to scale your business up or down as required.
  • Improved call quality: Experience better quality calls and fewer dropped connections compared to traditional phone systems.
  • Flexibility: Calls can be made and received from any location with an internet connection, providing increased flexibility for remote workers.
  • Integration with existing systems: Our SIP trunks can be easily integrated with your existing phone systems and software, allowing seamless communications between tools and applications.
  • Easy to install: Setup is easy and can be done without a site visit.
  • Business continuity: Calls can easily be rerouted to alternative locations or devices in the event of an outage, ensuring business continuity.
  • Advanced features: Access advanced features such as video conferencing, unified communications, and call analytics to improve collaboration and gain valuable insights into your phone system usage.
  • Improved customer service: Improve the call experience for your customers with call routing and queuing, voicemail-to-email, and automated attendants.
  • Centralised management: Manage all of your phone lines in one place for easy monitoring and usage control.
