Happy paying large quarterly rental charges just for the lines?  VOIP is less expensive than ISDN30, ISDN2e and PSTN. Our SIP channels (the VOIP equivalent of a single telephone line or ISDN channel) start from as little as £6.99 per month.

Still paying per call charges?  Our VOIP channels include 5,000 minutes of calls to UK landlines. Per channel. Order 2 channels and get 10,000 minutes per month. The more channels you rent, the more bundled minutes you get.

Still using ISDN or PSTN for your telephony?  Copper-wired telephony is being phased out by all UK telephony providers including BT, and being replaced by Voice Over IP technology.

With our cloud-hosted solution there’s no on-site equipment or infrastructure to maintain. You can be up and running quickly, allowing you to focus on running your business instead of managing your phone system.

Traditional PBXs or indeed black box appliances are difficult to scale. Add more extensions and you are hit by licensing costs, underpowered hardware or you run out of ports. Cloud PBXs are all the rage but they can lock you into expensive per extension and per minute pricing... Not so with our 3CX solutions.

The PBX offers easy to enable and manage security features such as IP blacklisting, SRTP encryption, automatic detection of SIP attack tools, provisioning of phones through HTTPS, SSL connectivity and an A+ rating from SSL Labs to boot.
