Cloud PBX has a considerable number of integrations and a very useful TAPI driver as well.

You are able to link your desktop, office phone, mobile phone, Instant Messaging, CRM and other apps for a total unified communications solution, delivered by our network.
Yes, business is changing: Nine times out of ten we will be talking to IT managers. You hardly see telecoms managers in business any more as voice increasingly sits under the IT umbrella.
A huge amount – your organisation’s entire communications, across multiple sites and countries, can be managed easily, right down to the individual user level, through a simple interface.
There is no up-front spend on hardware or software plus hosted telephony means no costly PBX maintenance or upgrades as we are responsible for the hardware and software, including system upgrades. You can also access low-cost and free IP calling.

A telephone system that resides in the cloud rather than in your office. Users access the system through a standard IP handset or a softphone – a screen-based virtual phone with headset. Calls are made/received over a broadband connection to our network. From there they are routed to PSTN fixed and mobile devices.

With only a minimal capital outlay required, Horizon is suitable for any size of business looking to improve its productivity and image.

A site survey is a useful exercise as it enables superfluous services and hardware to be identified, highlighted and considered during the decision-making process. As a cloud-based telephony platform, Citycom lets you dispense with a physical PBX and the associated cost of maintenance and it requires only the simple installation of on-site handsets. For larger, multi-sited customers the savings made will clearly be multiplied. Of course, as well as working seamlessly with our SIP, Ethernet and Broadband products, Citycom Cloud PBX can interface with legacy connections too, making it the totally flexible solution.

Cloud PBX is the perfect platform for organisations that require a professional and simple-to-use interface with the outside world. Schools, public sector organisations, major venue and event operators; each has its own challenges in terms of maintaining staffing levels, training and cost, with the result that often it’s the first line of communications that suffers. Citycom’s Cloud PBX is simple to set up and use and it lets you present a simple, flexible and, above all, totally professional image.

Call quality, as with any communications system, is clearly dependent on the underlying access available. With our Ethernet and Broadband products delivering the service to your locations, you can be assured of great voice quality, underpinned by some of the most stringent SLAs in the business.

Listening to your customers can offer a valuable insight into your organisation: maximising customer service, helping with staff training, and ensuring peace of mind when it comes to due diligence.

Gamma’s intuitive and secure call recording solution is deeply integrated with Citycom’s cloud platform, giving direct control to you over both your telephony and your call recording solution.

  • One intuitive software service – recordings can be accessed, downloaded and noted on from one web login.
  • Record the speaker, not the number – Advanced Call Recording will record your users, whether they are speaking on a mobile, office phone, or soft client.
  • Order and use on a native cloud platform – you’ll have a scalable investment, with a clear, usage based payment structure.
