Phone Systems

Reliable Communication. Anywhere.

Once you have your connectivity, next you need reliable communication systems. Grapevine Connect can create bespoke solutions that are tailored to your business, and the way you work.


Early adopters of 3CX Phone System, we now standardise on it for most of our VoIP deployments. 3CX is the fastest growing VoIP PBX vendor in the world. As one of just a handful of approved 3CX hosted providers, we’ve been hosting 3CX on secure publicly accessible servers since before it was known as the ‘cloud’, and bring with that experience deep understanding of SIP configuration and security.


Grapevine take the best enterprise grade VoIP server and wrap it in our secure cloud, providing our customers with a fully featured hosted VoIP solution – either as a fully managed cloud service, or as a self-managed cloud deployment.

Unified Communications

3CX is a software-based PBX, which not only replaces proprietary phone systems, it also delivers a complete Unified Communications solution as it’s an open standards software IP PBX which can be integrated with other applications such as Salesforce, Google Contacts and Sage ACT.


Other Systems

Whilst 3CX Phone system is our core telephony product we also install and support Alcatel, Panasonic and Horizon hosted telephony systems.

Cloud & On-Site Telephone Systems

We pride ourselves on our ability to design and implement a feature rich scalable telephone system solution that is tailored to your business and not the other way around.


More Options

There are still many instances where a cloud hosted VoIP solution is not the preference. For customers that need locally installed VoIP services we provide a range of hardware appliances and options or they can be deployed on your existing on-site server network.



ISDN lines in contract? Not a problem; Grapevine can connect existing PSTN/ISDN lines to our cloud PBX and these can be utilised for the remainder of the contract to limit early termination fee’s and migrate to VoIP trunks when your business is ready.


When there is a need to retain local telephone network connectivity via PSTN / ISDN for security, resilience or compliance purposes we offer a range of hardware appliances suitable to the task. From 2-10 handset deployments through to enterprise grade resilient server infrastructure for 100’s or 1000’s of local handsets – we’ve got you covered
