ISP BT Business Launch Sovereign Cloud Calling System for UK Firms
Communications and broadband provider BT Business has today announced the first product to be released as part of the company’s sovereign platform – ‘Sovereign Voice‘, which allows businesses to make and receive calls over a secure connection, while all call routing remains within the UK’s own borders.
The new service is said to be powered by Cisco Calling technology and aims to deliver a “highly secure, sovereign cloud calling” solution that offers to “future-proof business phone lines” and acts as a flexible alternative to traditional phone lines, which are currently due to be switched off at the start of 2027.
Unlike standard IP-based cloud voice services, Sovereign Voice ensures all call routing remains within UK borders. Naturally this means that the system is also hosted entirely in secure UK data centres and is managed by UK-based, security-cleared staff.

Kerry Small, Chief Operating Officer at BT Business, said:
“As sovereignty becomes an increasingly important topic for businesses across the globe it’s up to providers to step up and deliver the solutions customers need.
This is about giving businesses more choice and control over their services to boost resilience and meet regulatory obligations, all whilst enabling them to access technology from world-leading providers like Cisco.
Sovereign Voice is the first of our dedicated products to be made available to customers and marks a key milestone for our sovereign platform.”
Sadly the announcement didn’t include more information on the service’s other features or pricing.

Wasn’t “Sovereign”, (as in Project Sovereign), the name BT gave to one of its first early release schemes for managers in around 1991/92?
Will they also be avoiding the cables going by the new Chinese embassy. Although with all the fuss over end to end encryption and not providing back doors to government suggests it works and it would not matter even if the data stream went via Beighin.
You have to trust that the encryption endpoint is indeed the callee and not some man-in-the-middle who copies the data, re-encrypts it and passes it onwards.
Without this would UK to UK calls typically be routed out the country and back?
This feels like a “Let’s slap a name on what is already the norm” kind of deal to me…
The vast vast majority of reputable ISPs offering VOIP packages in the UK, route only through UK networks. When establishing a UK to UK connection…
Intentionally routing out of the country and back is definitely not the norm.
Internet based telephony van travel by any route. You wouldn’t typically expect intra UK calls to be routed internationally but they could be.
