 UK FreePBX Support, 30 Minute SLA 24/7

Professional Configuration, Management and Support of FreePBX & PBXact

24/7 FreePBX Support

Our telephony engineers are UK based, in-house, and on shift around the clock. FreePBX and Asterisk are not a line on a capability list here: our own telephony runs on it, we host cloud FreePBX and PBXact switches for customers in our own UK data centres, and we support every one of them ourselves. When a trunk drops at three in the morning, the engineer who answers is one of the people who runs that platform daily.

  • "No inbound calls since the trunk re-registered"
  • "One way audio on anything external"
  • "The switch has been hit for toll fraud overnight"
  • "Every call drops at exactly fifteen minutes"

Service levels run from a 4 hour response Monday to Friday through to 30 minutes, 24 hours a day, every day of the year including bank holidays. There is no support contract, no minimum term and no notice period: you buy hours at our published rates and you draw against them. Every tier reaches an engineer, because we do not employ anybody to read a script at you first.

We Run This Platform Ourselves

GEN's own telephony runs on FreePBX and Asterisk, and it has done for twenty years. Every call into our offices, every engineer on shift and every out of hours escalation passes through switches we built, maintain, monitor and upgrade ourselves. Alongside that estate we host a large number of cloud FreePBX and PBXact switches for customers in our own UK data centres, dedicated and shared, and we support all of them: the platform underneath, the switch itself, the trunks into it and the handsets on the end of it.


That is the difference at three in the morning. The engineer who picks the fault up is not reading a knowledge base article about a product nobody in the building has deployed. They are running the same versions, on the same kind of hardware, with the same trunk providers, and there is a fair chance they have already seen the fault on our own estate.


  • Our own production switches: GEN's telephony, queues, out of hours routing and engineer escalation all run on FreePBX, in-house, with no third party operating any of it.
  • Hosted cloud switches: dedicated and shared FreePBX and PBXact instances in our own UK data centres, on our own hardware and our own network, with hybrid on-premise and cloud designs where resilience demands it.
  • Supported by the people who run it: hosted, on your premises, or at another provider entirely, the same UK engineers take the case either way.
  • Watched around the clock: trunk registrations, call quality, disk, load and fraud patterns are monitored, so most of what we fix is raised by us rather than reported by you.

If a switch is down now, raise it on the HelpDesk or see emergency support.

We will continue to expand our services to include new features, improvements, and endpoints so we are always ahead of the curve.

SIP Trunking

Configuring and troubleshooting SIP trunking is a common occurrence for our technical team, with so many options and requirements from different providers, but we have setup and configured pretty much all of them over the years.


If you're looking for some DIY then head on over to the helpdesk FAQ where you'll find common FreePBX configuration examples for many SIP Trunking providers.

Technical Support

Our support packages range from a 4 hour response Monday to Friday 0900-1730 through to a guaranteed 30 minute response 24 hours a day, every day of the year including bank holidays. We understand that every business has unique requirements, which is why we offer flexible service level agreements to ensure you receive the exact level of support you need within your working budget. Five engineering shifts a day mean an overnight handover is a conversation between two engineers rather than a note left in a ticket. Our services encompass everything from basic break/fix solutions to full-service configuration and assistance, including proactive monitoring and management of your Asterisk environment.


We're committed to keeping your communications running smoothly, regardless of the complexity of your setup. Moreover, our expertise extends to a wide array of endpoint devices, allowing easy setup and support regardless of your choices.

How We Support It

Our engineers are UK based and in-house, with no offshore outsourcing: the specialist who takes your case is the specialist who works it, and they hold the production experience to match the equipment in front of them. Risk is assessed before anything is changed, the SAPR method is applied to every fault, and five shifts a day mean an overnight handover is a conversation between two engineers rather than a note left in a ticket. Our AI runs on our own hardware in our own data centres, and it never writes a word you read.

There is no support contract, no minimum term and no notice period. You buy hours at our published rates, use them when you need them, and what you do not use carries over. How GEN support works sets all of it out in full.
