Temporary phone systems
built for events.

We create two types of on-demand temporary VoIP telephone systems specifically for events and festivals — Event Production Hotlines and Community & Noise Report Phone Lines. Both are deployed within hours, require no fixed infrastructure, and are decommissioned cleanly when your event ends.

Service 01

Event Production Hotlines

Dedicated temporary VoIP phone lines for event production teams, crew coordination, artist liaison, media departments and operations. Each department or team gets their own dedicated UK number, custom voicemail and real-time call visibility.

  • Dedicated UK number per line
  • Custom voicemail greeting per department
  • Voicemail delivered to email inbox
  • Online portal with full call log
  • Live within hours of order
Service 02

Community & Noise Report Phone Lines

Dedicated noise complaint and community liaison phone lines for events and festivals. Provide local residents and the community with a real, staffed or voicemail-enabled number to report concerns. Fully logged, recorded and accessible via your online portal.

  • Dedicated noise report UK number
  • Custom community-facing voicemail
  • Every report emailed instantly
  • Full recordings portal for compliance
  • Supports licence & council requirements

Everything included in both services

Every on-demand VoIP line we create — whether a Production Hotline or a Community Noise Report Line — includes a dedicated UK phone number, a custom voicemail greeting recorded to your specification, automatic voicemail-to-email delivery as an audio attachment, and access to an online portal with full call logs and recordings. Lines are active only for the duration of your event. No long-term contracts.

Business telephony

Permanent VoIP systems
for your business

Beyond events, we provide full business VoIP and cloud telephony solutions for UK businesses of all sizes.

At Omnia Networks, we offer comprehensive business cloud and on-premises VoIP telephony solutions to help your business stay connected. Our certified team can assess your needs and recommend the best solution.

Whether you are looking to switch to a cloud-based phone system, upgrade your existing on-premises PBX, or connect a distributed team across multiple UK locations — we have the expertise and resources to get the job done.

3CX — our recommended platform

We are certified installers and resellers of 3CX, one of the world’s leading business communications platforms. 3CX runs in the cloud or on your own hardware and works on Windows, Mac, iOS and Android — giving your team a unified communications experience at a fraction of the cost of traditional phone systems.

Cloud vs on-premise

Cloud telephony (hosted PBX) is cost-effective and flexible — no on-site hardware, works anywhere, predictable monthly cost. On-premise PBX gives you full control, works without internet, and suits businesses with strict security or compliance requirements. We help you choose the right option.

Fully managed hosted PBX. No hardware to maintain. Works on any device from any location across the UK.

🏢

On-premise PBX

Hardware at your site for maximum control, customisation and data security compliance.
