Plug-and-play Business-Grade Communications with inclusive Free Calls to UK mobiles & Landlines. End-to-end Telephony & Mobile Solutions including Hosted VOIP (Cloud-Based PBX), SIP Trunks & Mobile.

Hosted VOIP

A solution that’s ideal for branch office, head office & contact centres.

Our VOIP telephony product is helping our clients save operational costs by removing the expense of ISDN/Copper and on-premise phone system installation and maintenance. Additionally, our solution offers free calls to 01,02 and 03 numbers and UK mobiles with a pooled fair use policy of 2000 minutes for landlines and 2000 minutes separately itemised for mobiles which is an industry leading, best in class offer from our upstream provider, Gamma, that is only available via their accredited partners such as Force36 Limited.

Our phone system deployment requires simply 40Kbps/40Kbps per channel of internet bandwidth meaning that even an ADSL2+ circuit will support a small branch deployment and that’s it, no phone system hardware PBX and, even better, no long lead times for installation. Typically we can get a phone system deployment up and running within a week or so.

Live monitoring via Akixi can be integrated for contact centre deployments allowing for live call statistic reporting and even call board display.

All handsets sit on the same ‘phone system’ regardless of their geographical location, meaning that 3 or 4 digit extension dialling, call transfers and call management is possible between sites and in the event of a local failure of power or broadband an automated DR facility will automatically re-route inbound calls to pre-determined numbers of your choice including mobiles or another site on the system for example.

Which Providers? With the mobile network industry being fierce we wanted to ensure we provide our customers with the best possible solution.

SIP Trunking

SIP trunking is the fastest-growing telephony service and Force36 provides one of the UK’s leading SIP trunk solutions. It connects your site directly into the Gamma network via an IP connection to carry and terminate your inbound and outbound voice calls across the public telephone network.

Our SIP Trunks provide a highly-flexible alternative to ISDN and are compatible with all the leading IP PBX brands in the UK market, giving you peace of mind that your PBX hardware works with the network service.

Compared to ISDN, Force36 SIP Trunks are cheaper on a per-channel basis and more flexible in terms of what telephone numbers you can have and the locations in which you can have them. In addition, they are quicker to install and offer a robust business continuity service that ensures your business never loses any calls.

Our service can support connections ranging from two channels for businesses with small PBXs, with no limit on the number of channels that can be supported for large enterprises and contact centres.
