Voice & Mobile
Voice & Mobile: Hosted telephony
Hosted voice running in our own Tier 3 data centres, from single-site telephony to enterprise-scale SIP trunking, with Microsoft Teams integration built in. Business mobile managed on the same account.
Overview
Our Voice and Mobile Service
Synapse hosted voice scales from a single office system to enterprise-wide SIP trunking, supporting between 6 and 6,000 users on the same platform. The virtual PBX runs inside our own Tier 3 data centres in Douglas, Isle of Man, carried over the group’s fibre network, so the call path, the platform and the accountability sit with one provider.
Calling, messaging and meetings are delivered through Cisco Webex, with Microsoft Teams integration built in rather than added on. Business mobile is managed through a single platform on the same account relationship, giving fleet-wide cost, usage and device control instead of a stack of individual contracts.
Benefits
The benefits of Voice & Mobile
-
One platform from 6 users to 6,000
The same system runs a single site or an enterprise-wide deployment, so growth, acquisition or consolidation doesn’t mean replacing the platform and retraining everyone on it.
-
Voice that runs on infrastructure we operate
The virtual PBX sits inside our own Tier 3 data centres, carried over the group’s own fibre backbone with six diverse subsea routes off-island and edge DDoS protection through our transit partners. Call quality and resilience aren’t dependent on someone else’s network.
-
Ready for the PSTN switch-off
The UK’s copper phone network is being retired nationwide by 31 January 2027. Moving to hosted voice now turns a forced migration into a planned one, on your timetable rather than Openreach’s.
-
Built around Microsoft Teams
Teams integration runs alongside voice on the same platform, backed by the Microsoft Solutions Partner status we already hold across our cloud services.
-
Works the same wherever people are
Because voice runs over connectivity we operate, call quality holds whether people are in the office, at home, or moving between sites.
-
Mobile managed as a fleet, not a pile of contracts
Business mobile is managed through one platform: cost centre allocation by office, department or role, real-time spend and usage visibility, device security controls, usage restrictions and spend limits, set centrally rather than handset by handset.
