Frequently Asked Questions

Omnixi is a managed business communications provider. We deliver mobile, VoIP, broadband, networking, IoT connectivity, cyber security, and custom integrations — all managed through one intelligent platform. We're a trading name of Signal Solutions Ltd.

We work with UK businesses of all sizes, from 10-person offices to multi-site enterprises. If your business relies on communications and connectivity, we can help.

Three things: our intelligent platform gives you visibility and control that most providers can't match, we proactively manage your services instead of waiting for you to report problems, and we're genuinely transparent about pricing and advice.

We're a UK-based company with UK-based support. When you call us, you speak to someone who knows telecoms and knows your account.

We work across all major UK networks including EE, Vodafone, O2, and Three. We recommend the best network — or combination of networks — based on your coverage needs.

Yes. We handle the full number porting process with no disruption to your service.

Yes. We offer SIM-only plans for BYOD setups, or we can supply handsets as part of the package.

VoIP works over any decent broadband connection. We assess your connectivity as part of the setup and can provide business-grade broadband with QoS settings if needed.

Yes. We port all your existing numbers — geographic and non-geographic — across to the new system.

VoIP replaces your entire phone system with a cloud-hosted solution. SIP trunking keeps your existing PBX hardware but replaces the ISDN lines with internet-based trunks. We can advise which is right for your situation.

Most modern IP-enabled PBX systems support SIP trunking. We carry out a compatibility check as part of the initial assessment.

BT is retiring the PSTN and ISDN network by 2027. If your business uses ISDN lines, you'll need to migrate to an alternative — SIP trunking is the direct replacement.

It depends on the infrastructure available. We'll run a postcode check and tell you exactly what's available — FTTP, FTTC, or whether a leased line would be the better option.

We'll likely know before you do. Our monitoring detects outages automatically, raises a fault with the carrier, and keeps you updated. If you have 4G/5G backup, your connection fails over automatically.

Typically 30 to 90 working days, depending on circuit type and whether any civils work is needed at your site.

It depends on your requirements. If you're running VoIP, cloud-critical applications, or need strong upload speeds and guaranteed uptime, a leased line is worth the investment. We'll help you decide.

Always. We won't quote a networking project without understanding the physical space and your requirements. The survey is free.

In many cases, yes — especially if it supports cloud management. We'll assess your current kit and advise.

IoT SIMs are designed for machine-to-machine communication. They're more robust, support multi-network roaming, offer remote management, and come on data-only plans optimised for device usage patterns.

Yes. Pooled data plans spread a single allowance across your entire device estate for better cost efficiency.

You need the Microsoft Phone System capability, included in E5 licences or available as an add-on for E1/E3 and Business plans. We'll advise on the most cost-effective path.

Yes. We handle the full porting process so your team keeps their existing DDI numbers.

With an assessment. We look at what you've got in place, identify gaps, and recommend a practical plan — starting with the highest-impact measures.

Yes. We support the full Cyber Essentials and Cyber Essentials Plus certification process.
