PBX phone systems

A PBX or Public Branch Exchange Telephone System is what many people would refer to as a ‘traditional’ phone system. Unlike a ‘hosted’ system where all of the call routing, etc, is ‘in the cloud’ and delivered via the internet, a PBX is located in your office with telephone lines and extensions wired to it.

Although the industry is now very much focused on ‘hosted’ cloud solutions, there are some cases where a PBX is the preferred option. For example large call centres with hundreds of extensions, remote rural locations where the broadband isn’t fast enough for VoIP, or a hotel where direct software integration is needed. In these cases we can provide an on-site system.

VoIP - Voice over IP

VoIP or Voice Over Internet Protocol is a term that covers a number of different applications. Essentially VoIP is the use of the internet to transport your voice data between different locations. This can result in a dramatic cost reduction, tremendous flexibility, and improved productivity.

You may be moving offices and not be able to retain your telephone number due to the distance you are moving. You can with a VoIP solution from Halo Digital. We can port your BT numbers into our system so you can take them wherever you like.

SIP trunking

SIP trunks are telephone line trunks delivered over IP networks using the SIP protocol. By using this standard protocol, telecom service (VoIP) providers connect one or more channels to your PBX. Phone numbers and DIDs are linked to the SIP trunk. The benefits range from significantly lower call charges and monthly line rental to flexibility and our excellent customer service.

    Most frequent questions and answers

    How does VOIP technology work?

    VoIP is a communication technology that utilizes the internet to transmit phone calls. By converting analogue voice signals to digital signals, VoIP can transmit data over your broadband line. This technology is cost-effective because digital signals are more efficient than analogue signals.

    Are VoIP phones secure?

    VoIP technology relies on your broadband network to make calls, and the security of your phone network is dependent on the security of your internal network. To ensure the security of your VoIP system, it is essential to prioritize security measures during its implementation. At Halo Digital Ltd, we place a strong emphasis on security when assessing your system for VoIP readiness, so you can be assured that your phone network is protected against potential security breaches.

    Is it possible to utilise your current Fibre or ADSL line?

    Certainly, it is possible to use your existing Fibre or ADSL line, provided that you have available bandwidth. However, the number of calls you can make at any given time will depend on the amount of spare capacity available on your line. We recommend consulting with our experts regarding the Quality of Service to ensure optimal voice experience. They can provide guidance and recommendations to ensure the best possible audio quality for your VoIP phone system.

    Will a VOIP phone system save our business money?

    A VoIP phone system can save money in several ways. Traditional phone systems require costly on-premises equipment, whereas VoIP systems can be set up and managed through software on your computer, reducing hardware expenses. Our systems transmit calls over the internet, bypassing the traditional phone network and reducing costs of long-distance and international calls. Calls to 01/02/03 & UK Mobiles are free.

    Can staff make calls from home or while they are out and about?

    With VoIP systems, remote staff can access the same phone system as their in-office colleagues from anywhere with an internet connection. This eliminates the need for additional phone systems or costly hardware. By using our smart app, you can work from any device with an internet connection, providing even more flexibility and mobility for remote staff members.

    Is it possible to transfer my current telephone numbers to a VoIP system?

    Absolutely, we can facilitate the transfer of your current telephone numbers to our VoIP phone system, managing the porting process on your behalf. During the setup, we will assign a temporary number, which you can redirect your current telephone number to. We will then handle the porting process in the background, which will be completed in a few working days.
