Hosted Voice

Fully cloud-based phone system built on BT Wholesale WHC 3.0. Replace your analogue setup with a modern, scalable IP voice platform — Hosted PBX or SIP Trunking.

🟦

TeamsLink

Add external phone calls directly into Microsoft Teams. No third-party app needed — full enterprise PBX features including hunt groups, auto attendant and call recording.

🔗

SIP Trunks

Replace legacy ISDN with modern SIP trunking. Keep your existing on-site PBX and move your calls to IP — ready for the 2027 PSTN switch-off.

📡

Business Broadband

SoADSL, SoGEA and FTTP options with static IP as standard. Business-grade connectivity from our network of wholesale ISP partners including BT and TalkTalk.

Leased Lines

Dedicated, uncontended Ethernet circuits up to 1Gbps. Symmetric speeds, full SLAs and guaranteed fix times — ideal for businesses that cannot afford downtime.

🌐

SD-WAN

Intelligent, software-defined wide area networking that optimises traffic, reduces costs and provides resilient multi-site connectivity with centralised management.

💾

Backup & Recovery

Protect your business data with automated cloud backup and rapid recovery. Secure, compliant and always on — so you are never caught out by data loss.

🛡️

DDoS Protection

Always-on DDoS attack mitigation that scrubs malicious traffic before it reaches your network — keeping your services available even under attack.

🔥

Hosted Firewall

Enterprise-grade firewall protection delivered from the cloud. No on-site hardware to manage — we handle updates, monitoring and threat response for you.

The PSTN switch-off is coming in 2027

Every UK business running on analogue lines must migrate to IP voice. Centric Comms will make that transition simple and stress-free with Hosted Voice or SIP Trunks.
