Frequently Asked Questions

What is a Cloud Hosted PBX?

As with an on-premise PBX, a Hosted PBX provides your business with communication features such as call-transfer, on-hold, auto-attendant, voicemail, call forwarding and more. The difference with a Cloud Hosted PABX, is that it is hosted at an offsite data center and is powered and managed through the internet as opposed to copper landlines. 

How does a Cloud PBX work?

Phone calls are transmitted via VoIP lines and routed to and from the data center where the servers are stored. All VoIP phones have a unique IP address, a Hosted PBX renders the public phone network to an IP address. When dialing a telephone number, the phone system renders the public phone network to an IP address. When dialing a telephone number, the Hosted PABX switch finds the IP address and sends the phone call to the VoIP phone.

What connectivity do I need?

There are various forms of connectivity available to businesses in the United Kingdom. Depending on the number of extensions you require, United Telecoms will advise you on which connectivity solutions is best for you, these include; LTE, Fibre and Wireless/Microwave.

Can I use my smartphone as an extension?

Yes, the UVC mobile app enables you to receive calls made to your office extensions on your smartphone device as well as dial other extensions. In addition, you can update your availability at any time and check fellow colleagues' presence, the app also enables you to keep all of your business connections on your device with you at all times. 

What hardware is required for a Cloud Phone System?

Since the PABX system itself is hosted at a data center, the only primary items of hardware required for the solution to function are IP handsets. If you require additional network equipment, this can be provided at an additional cost.

What type of phones can I use with a Hosted PBX?

You have the option to use any type of device that is supported by the Cloud switchboard. This includes a softphone, desktop IP phone, or smartphone using the mobile app. Some of the IP phone brands that can be used include; Snom, Yealink, Grandstream and Polycom.

Can I use my existing internet service?

Yes, you can use your existing internet service however it is imperative to use a reliable form of connectivity such as LTE, Fibre or Wireless. United Telecoms will conduct an audit on your current infrastructure and confirm whether it is feasible to run the Hosted PBX on it. We support all internet connectivity types excluding ADSL.

What costs are involved?

The United Voice Cloud solution comprises a monthly subscription fee per extension, once-off hardware costs that can either be purchased outright or financed on rental as well as a once-off installation fee.

Can I keep my landline number if I switch to a Hosted PBX?

Yes, you can. You can move any geographic number from any existing service provider to your VoIP service provider, including United Telecoms.

How quickly can a Cloud Phone System be deployed?

Depending on whether or not connectivity is required and subject to feasibility if the site is ready, we can deploy the hosted switchboard system within hours of the order being placed.

What uptime guarantees do you provide?

This depends on your connectivity solution. If you choose to take our Enterprise Fibre or Wireless product, our uptime guarantee is 99.8%. All other connectivity solutions are best-effort service. Further redundancy measures can be put in place upon request. In addition, calls can be routed to your mobile device at any time.

What happens if there is a power outage?

For traditional on-site PBX's, a power outage can interrupt communications until the power is restored. However, as long as your network is connected to the internet, calls can be made and received through the Cloud PBX. United Telecoms will supply you with a UPS for the network which serves as a backup for a couple of hours. Additionally, the UPS will regulate power output to network equipment preventing surges. It is also recommended to use PoE switches, this will ensure the entire network is powered during an outage.

What if I have multiple business locations?

This is the perfect product for you. Having your PBX hosted in the cloud will allow you to register a device in any location nationally or internationally. The device that is registered to the Hosted PBX is allocated an extension number, each extension can dial other extensions as if in the same location.
