Question 1

How does IP technology work?

Accepted Answer

In contrast to standard telephone systems, which use landlines to transmit analogue signals rather than digital ones, IP telephony connects to the internet.

IP telephony works through a process of translating users’ analogue voice data into digital data – this is achieved using another technology referred to as Public Switched Telephone Network (PSTN).

This involves a process of scanning and identifying speakers’ voices and, once the transformation has taken place, the signal is transmitted through what is called a ‘broad line’ in digital format – replicating the way a traditional landline phone conversation works.

Finally, this voice data is then directed in and then out of the network via an IP system, before being transferred directly into the internet connection.

Question 2

What are the benefits of IP technology?

Accepted Answer

There are numerous benefits to using IP telephony over traditional phone systems, including scalability, flexibility and cost-savings.

1. Cost reduction compared to landline
One major benefit to businesses choosing to use IP telephony over traditional landline telephone systems is a reduction in the overall cost required to run the network.

What’s more, these costs are often more predictable and consistent compared to analogue solutions which rely on telephone network providers’ prices.

2. Scalable and future-proof

Since IP telephony has far fewer restrictions than analogue systems, it makes scaling your business line much easier.

IP telephony gives businesses full flexibility, allowing the organisation to add or remove lines as necessary simply and quickly with no added cost – so wherever your business is headed, your telephone system can handle it.

What’s more, no additional technical skill is required in doing so, as lines can be managed, added or removed easily via a simple online interface.

3. Remote work capability

With so many individuals and organisations now at least partially (if not fully) remote, the lack of an office need not hinder our ability to work effectively. IP telephony allows workers to efficiently work remotely as there is no requirement for physical hardware.

As well as convenience, this flexibility means that workers and businesses are no longer tied to a single location, allowing for easier growth, hiring and communication across the board.

4. Higher call quality

Because it is connected to the internet, using IP telephony means workers can enjoy much higher call quality on average than those using analogue systems.

Many systems, including our own, offer users crystal clear HD audio quality, meaning work can be done more easily and efficiently no matter what it is.

5. Advanced, modern features

When it comes to added features and capabilities, physical telephone systems have many limitations relative to IP telephony technology.
When using IP telephony, users can take advantage of a host of rich collaboration tools and features, including, but not limited to: video and audio conferencing, automatic call recording and automatic call back.

Thanks to rapid increases in the sophistication of telephone systems in recent years, very little is needed for your business to switch to IP telephony technology.

Question 3

What are the requirements of IP telephony?

Accepted Answer

Thanks to rapid increases in the sophistication of telephone systems in recent years, very little is needed for your business to switch to IP telephony technology.

While these factors will depend to some extent on the size of your organisation and how much data you expect it to use, the only basic requirements are a reliable and fast internet connection and dedicated IP phones supplied by BT.

Question 4

What’s the difference between IP technology and VoIP?

Accepted Answer

You might find yourself wondering if there is any difference between IP telephony and VoIP systems. The terms IP telephony and VoIP (Voice Over Internet Protocol) are often used interchangeably. However, there is a subtle difference worth bearing in mind.

Although both use the same means to connect to the internet – a LAN (Local Area Network) – VoIP phone systems for business refers exclusively to a system designed to transfer voice signals from analogue to digital and transport those signals using the internet.

In other words, IP telephony is a concept under which VoIP systems sit as a subcategory.

Question 5

What’s the difference between cloud and IP telephony?

Accepted Answer

Cloud telephony is an internet-based service that lowers the cost of a business phone solution by removing the need for expensive equipment at the business premise. It’s an application of VoIP technology that provides more advanced features and flexibility by leveraging cloud infrastructure.

While IP technology does encompass cloud telephony, it also includes SIP. This is an internet-based telephone numbering solution to enable legacy premise-based equipment.

Question 6

What implications does the move to all-IP have on my broadband?

Accepted Answer

Many traditional broadband services, including fibre to the cabinet (FTTC) or standard broadband (ADSL) rely on the PSTN. As a result, this won't just affect voice services, the move to ip means you will also need to upgrade your broadband to a new fibre access.

Question 7

What are the challenges of IP telephony?

Accepted Answer

The main challenge users and organisations might face from implementing IP telephony systems is that the quality of service is entirely dependent on the strength of the internet connection the technology uses.

A second obstacle that can present itself with IP telephony is the fact that not all internet providers have a secure network, which can present a challenge.

Luckily, both issues can be easily resolved by taking the right steps at the start of the switching process to ensure that the provider you choose and the set-up you have are suitable for the requirements listed above.
