Overview

Communications that adapt to how you work.

Traditional phone systems are costly, inflexible, and limited in functionality. Luminous X Technologies delivers cloud-hosted PBX, SIP trunking, VoIP desk phones, auto-attendant, conferencing, voicemail-to-email, and unified communications solutions that modernise how your business communicates.

Our VoIP solutions reduce costs, improve flexibility, and enable seamless collaboration across offices, remote workers, and mobile devices, all managed from a single cloud platform.

Audit

Review current telephony, call volumes, extensions, and features actually used across your team.

03

Deploy

Configure PBX, provision handsets, and port numbers with minimal downtime, often zero for ports.

04

Train

Train your team on features, mobile apps, and collaboration tools so adoption is instant, not gradual.

Why VoIP

What changes when you switch.

Lower call costs

Significant savings, especially on inter-branch and international calls.

Instant scalability

Add or remove extensions instantly, with no physical lines to install.

Work from anywhere

Softphones and mobile apps let your team take calls on any device.

Advanced features standard

IVR, recording, analytics, and conferencing, with no premium add-ons.

CRM integration

Click-to-call, screen pops, and call logging into your CRM.

Less hardware

No PBX room or copper lines, just internet and devices.

Common Questions

Things clients ask us.

Can we keep our existing numbers?

Yes. We port your existing landline and mobile numbers to the cloud, typically with no downtime during the switch. Your customers won't notice the change.

What internet speed do we need?

Roughly 100 kbps per concurrent call. A 10 Mbps link comfortably handles 50+ simultaneous calls plus normal data traffic. We'll measure during audit.

What if our internet goes down?

We recommend a backup LTE/5G failover for critical lines. Call routing can also fail over to mobile numbers automatically, so you never miss a customer call.

Can we integrate with Microsoft Teams?

Yes. We offer Teams Direct Routing and native 3CX Teams integration. You can make and receive calls from within Teams without switching apps.

How long does migration take?

A single-office migration typically runs 1–2 weeks. Multi-site or contact centre migrations run 3–6 weeks with phased cutovers.
