Teams Direct Routing in the UK for Telecommunications

Professional PSTN calling within Teams, tailored for UK telecoms companies.

Lower Call Costs

SIP trunk rates are typically 30 to 50 percent cheaper than Microsoft Calling Plans, with competitive UK and international rates.

Greater Flexibility

Keep your existing numbers, choose your SIP provider, and configure call routing exactly how your business needs it.

Expert Management

Direct routing configuration is complex. We handle the session border controllers, SIP trunks, and Teams policies so you do not have to.

For telecoms companies that have adopted Microsoft 365, maintaining a separate phone system is an unnecessary expense. Direct Routing eliminates that duplication, letting your support and sales teams handle all calls within the Teams app they already use daily.

Cloudswitched implements Teams Direct Routing for UK telecoms companies, connecting your existing phone numbers to Microsoft Teams so support and sales teams can make and receive external calls from the desktop, mobile, or web Teams app without any additional software.

How it works for Telecoms businesses

A clear, structured process from consultation to ongoing support.

Number Management

We port your existing UK numbers and provision new ranges as needed, managing the relationship with carriers so you have a single point of contact.
