Asterisk support and FreePBX support from the people who run both. We support bare Asterisk, with hand written dialplan, AGI, AMI and ARI and no web interface anywhere near it, and FreePBX and PBXact switches alike. GEN's own telephony runs on Asterisk and FreePBX, we host cloud switches for customers in our own UK data centres, and our telephony engineers are UK based, in-house and on shift around the clock.
Service levels run from a next business day response 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 draw against them, and every tier reaches an engineer.
GEN's own telephony runs on Asterisk and FreePBX, 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 Asterisk, FreePBX and PBXact switches for customers in our own UK data centres, and we support all of them: the Linux underneath, the switch itself, the dialplan, 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.
The same engineers install and support switches of every size, from compact appliances in small offices with fewer than 100 endpoints to multi-site enterprise deployments of more than 10,000.
If a switch is down now, raise it on the HelpDesk.
A great deal of Asterisk in production has no GUI on it at all, and that is where most support offers stop. A switch built by an engineer who has since left, a dialplan written against a specification nobody kept, an appliance shipped inside somebody else's product: these are the systems we are usually called about, and they are supported here as first class work rather than as an exception. Where nobody on your staff understands the switch any more, we audit it, document it and take it on from there.
extensions.conf read, documented and rewritten where it needs to be, including the older Macro and GoSub patterns and AEL. IVRs, multi-tier call routing, and call flows that grew a case at a time until nobody could follow them.
chan_sip to chan_pjsip, with endpoint, AOR and identify configuration, DAHDI and analogue or ISDN cards where they are still in service, and the codec and transcoding decisions that go with them.
Integrations with CRM, ERP, databases, web services and line of business systems: screen pops, outbound dialling campaigns, click to dial, real time call control and call analytics, and the scripts that quietly stopped working after an upgrade.
Asterisk compiled from source, module selection, patched builds, pinned versions for embedded and appliance use, and a build reproduced for hardware whose original supplier has gone.
One way audio, RTP port ranges, SBC and firewall behaviour, direct media, jitter and packet loss, traced with captures rather than guessed at.
Exposed SIP ports, weak endpoint secrets, fail2ban and rate limiting, dial pattern restrictions, and the post-incident work when a switch has already been used to dial premium rate destinations overnight.
FreePBX and PBXact put a web interface and a module system on top of Asterisk. We have worked with FreePBX for twenty years, from its early days under Schmooze to its current stewardship by Sangoma, and have deployed thousands of installations. Whether your switch sits on your premises, in our data centres or with another provider, FreePBX support and PBXact support come from the same engineers.
Tailored advice on system design and deployment for open source telephony. We discuss what the business needs and propose the most effective and efficient way to deliver it.
Proactive monitoring, regular updates, upgrades and prompt troubleshooting, keeping FreePBX and PBXact switches secure, reliable and performing as they should.
Bespoke FreePBX functionality, from advanced call routing to integrations with CRM and ERP systems. See IP Voice for more.
Our own FreePBX modules cover CRM integration, API exposure, automation, hooks and more, and our repository of code examples on GENWiki is free to use.
Dedicated and shared FreePBX and PBXact hosting in our own UK data centres, and hybrid designs mixing on-premise and cloud for resilience and coverage. Nothing is sublet to a third party platform and nothing leaves the country.
Asterisk and FreePBX are open source, so a switch can be audited, extended and adapted to the business without waiting on a single vendor's roadmap, and a well maintained one runs for years without a crash. GEN contribute code and documentation back to the community, and the GENWiki holds source code and resources free to use. Frameworks have come and gone over twenty years, Fonality, Elastix and FreeSWITCH among them, and we have supported them all.
Configuring and troubleshooting SIP trunks is everyday work for our engineers. Every provider has its own options and requirements, and over the years we have set up pretty much all of them.
If you would rather do it yourself, the HelpDesk knowledge base holds configuration examples for many SIP trunk providers. They are written against FreePBX, and the underlying pjsip settings are the same on a bare Asterisk switch.
At the other end of the line we support a wide range of handsets and endpoints, so setup and support work whichever brand you have chosen, and the engineers who look after the switch look after the phones on it too.
Yes. A great deal of Asterisk in production has no web interface at all, and GEN support it as first class work: hand written dialplan in extensions.conf and AEL, AGI, AMI and ARI integrations, builds compiled from source, and switches whose original engineer has long since left. Where nobody on your staff understands the switch any more, GEN audit it, document it and take it on from there.
Yes. GEN have worked with FreePBX for twenty years and have deployed thousands of installations. GEN's own telephony runs on FreePBX and Asterisk, and GEN host FreePBX and PBXact switches for customers in their own UK data centres. Support covers consultancy, maintenance, upgrades, custom modules and bespoke development.
Every release from Asterisk 1.4 through to the current one. Asterisk 1.4, 1.6, 1.8, 11, 13, 16 and 18 are end of life and still supported by GEN, alongside Asterisk 20 LTS, 21, 22 (the current LTS) and 23. GEN also support the legacy frameworks built on them, including AsteriskNOW, Elastix, PBX in a Flash and Fonality.
Yes. GEN carry out chan_sip to chan_pjsip migrations, including the endpoint, AOR and identify configuration, the codec and transcoding decisions that go with them, and any DAHDI, analogue or ISDN cards still in service on the same switch.
Raise it on the HelpDesk and GEN will carry out the post-incident work: exposed SIP ports, weak endpoint secrets, fail2ban and rate limiting, and dial pattern restrictions so premium rate destinations cannot be dialled again. On the switches GEN watch, fraud patterns are monitored around the clock.
Yes. GEN host dedicated and shared Asterisk, FreePBX and PBXact switches in their own UK data centres, on their own hardware and network, and design hybrid on-premise and cloud systems where resilience demands it. Nothing is sublet to a third party platform and nothing leaves the country.
Over the years GEN have configured pretty much every SIP trunk provider there is, each with its own options and requirements. Configuration examples for many providers are kept in the GEN HelpDesk knowledge base, written against FreePBX, with the underlying pjsip settings the same on a bare Asterisk switch.
No contract, no minimum term and no notice period: you buy hours at published rates and use them as you need them. Service levels run from a next business day response through to 30 minutes, 24 hours a day, every day of the year including bank holidays. Every case is taken by an in-house UK engineer.
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.
