Our solutions are crafted to enhance the efficiency of your operations and significantly reduce your communication costs.
PSTN and ISDN are being retired:
In January 2027, the UK's analogue phone network is being permanently switched off.
31 January 2027.
The deadline is final — there will not be another extension.
Every UK business on a landline:
Landlines, ISDN lines, on-site phone systems — all need to migrate.
If your team already uses Teams for chat and meetings, it can also handle every business call.
No new app, no new platform — for most Microsoft 365 customers, this is the simplest path off PSTN.
Use your business numbers for every customer conversation — not personal mobiles.
Work from any device. Run your business line on a SIM, a softphone, or both.
Customer conversations belong to your business. Not the phone in someone's pocket.
One provider. Voice, mobile, and messaging in one system.
WhatsApp under control. Customer chats stay with the business.
One messaging system across every site. Tenants reach the right team.
Patient conversations stay with the practice. Continuity always.
Microsoft Teams calling, multi-site campuses, term-time peaks.
Client comms you can audit. Hybrid working, full oversight.
One conversation. One quote. Response within one working day.
