Using Infinitel’s carrier-grade voice platform, you’ll have all the features you’d expect from a traditional phone system, but with global coverage and full PSTN replacement.
Compatible with Microsoft 365 Business Basic, Business Standard, Business Premium, E1, E3 or E5 with the Microsoft Phone System or Business Voice licence.
Our team is on hand and ready to help you and your business. If you need help finding a solution for your business mobile phones, business internet or phone systems and want to benefit from the best customer service and expert advice in the industry, contact us today on 0333 996 0029 to begin your journey to a faster, easier and more efficient business.
Simplicity Manage one unified and consolidated audio, video, and web conferencing solution rather than several products from multiple providers. Because it’s all done over the Internet and hosted within the Infinitel cloud, Direct Routing doesn’t require you to install and maintain an on-premise phone system, saving you time, money and hassle.
Global SIP network We connect your business to the world with our SIP Trunks and Microsoft-Certified Session Border Controllers (SBCs). We guarantee the highest quality calls and global coverage with full PSTN replacement in 40+ countries and number coverage in 100+ countries.

With Direct Routing, we provide more than 4 times the coverage, allowing your business to communicate with the rest of the world using Microsoft Teams.

Cost effective Dramatically cut down on your call costs with Infinitel’s SIP Trunks.

We offer simple and cost-effective per channel pricing; all of our pricing is clearly structured and transparent with no hidden costs.

Infinitel delivers excellent value compared with Microsoft Calling Plans and allows us to use a single provider for all our global communications. The working relationship with Infinitel and their fast response times have made a real difference to the success of this project.
Travelzoo now has a full cloud-based telephony solution, enabling our end users to make and receive external calls directly from Teams.”

Many UK businesses still rely on traditional PBX phone systems. Otherwise known as ‘analogue’ PBX systems, these originally saw widespread adoption among 20th-century businesses eager to make phone calls without having to rely on public phone lines.
More and more PBX systems were enhanced with the following features later in the century:
Analogue PBX systems connect to the Public Switched Telephone Network (PSTN) – but if your business still uses a traditional PBX, you should be mindful of ‘PSTN Switch Off’.
Many companies will be cut off from the PSTN on 31st December 2025. However, with our help, you can use Direct Routing to upgrade your existing onsite PBX hardware, connecting it to our reliable, cutting-edge network in place of the PSTN.
All Infinitel customers have access to the following support:
When it comes to business telephony, there is no ‘one-size-fits-all’ solution.
The price you pay us to set up your direct routing will depend on the maximum number of concurrent calls your workforce will need to make. Unlike the case with Microsoft Calling Plans, you wouldn’t have to pay extra for each individual user.
Still, as your business grows, it might need some new phone lines – for example, for new departments or offices. We would be happy to add additional SIP trunks to your Teams system, enabling employees across various sites to seamlessly communicate and collaborate with each other.
An SBC (Session Border Controller) is a device purposely built to protect and regulate the calls you make using an internet connection. An SBC protects your connection from attack and regulates your calls to provide great quality of service and efficient routing – improving the quality and safety of your calls.
We are partnered with Ribbon and use their Microsoft-certified SBCs for our Direct Routing. They are one of only a few vendors recognised by Microsoft. This means that our Direct Routing for Microsoft Teams is fully supported by Microsoft itself.
