How to fix Gamma not working
Gamma is up on our end, so if it won't work for you, the problem is most likely on your side. Work through these in order:
Your browser tries to reach gamma.co.uk over your own connection, right now. Nothing is sent to us or stored.
Check the Gamma status note
The note at the top of this page shows whether user problem reports for the service are above their usual level in 15-minute windows over the last 24 hours. If it is high, wait and try again before you change any settings; if it is normal, the fault is more likely on your side.
Test a second Gamma device
Ask a colleague on the same account or extension to make a test call; that narrows the fault. If their call works, focus on your own phone or network connection. If it fails too, stop changing your settings and report the shared fault.
Restart the app and handset
Close the app fully and reopen it; sign in again if you are prompted. On Windows, end any leftover app process in Task Manager before you relaunch it, and for a desk phone, unplug the power or Ethernet cable for 30 seconds before you plug it back in and let it register.
Call your Gamma admin
Give your admin exact details. Your IT or telecoms admin needs the time of the failed call and the exact message on screen so they can check your extension and open a ticket with Gamma support; if the fault is only on your device, ask them to compare your extension settings with a working colleague before you change anything else.
While Gamma is down: what to use instead
- Mobile phone If calls through the hosted phone system fail, use a mobile or ordinary landline to keep the conversation going.
- Microsoft Teams For internal chat, calls or quick meetings, Teams works if your organisation already has it set up.
- Zoom Use Zoom for a scheduled meeting when the usual business phone or meeting link will not connect.
- Email Send a short written update by email when you need a record and voice or chat is unreliable.
Problems at the same time as Gamma
Since 9 November, all 2 of Gamma's spikes in problem reports overlapped a spike at another service.
When several services get problem reports at once, something they share, such as a cloud host or a network, can be the real cause. Matching times alone do not prove it.

What happens when Gamma goes down
Gamma is a UK business communications provider with cloud phone systems, SIP trunking, mobile and connectivity for offices and contact centres. An outage blocks incoming calls, outgoing calls, voicemail and the apps tied to those services, so your sales and support teams lose their main way to reach customers.
The first sign is a desk phone or softphone that cannot register, so incoming and outgoing calls fail before they connect. Calls over SIP trunks may return a busy tone or drop mid-call, while voicemail and call routing lag and the mobile app refuses a login; the fault often sits in one product or one region rather than the whole UK network. Test a second product or a colleague's line. If both fail, the problem is wider than your handset.

How we track Gamma
The status on this page comes from user-submitted problem reports for Gamma, counted in 15-minute windows over the last 24 hours. Each window is compared with the normal level for Gamma, so a few complaints on a quiet day don't trigger anything, but a sudden jump well above normal does.
When reports climb well above normal, the status here changes to partial outage or major outage and the chart moves with it. Gamma doesn't publish a public status page that we know of, so user reports are often the quickest sign that something is wrong on their side.
