Siemens Business Phones Review



Siemens is a name that has been around for almost 200 hundred years.

They operate in a vast number of fields from electronics, railways, and communications.

Today you can see their products and services in more than 60 countries around the world.

However, Siemens has moved away from their focus on phones in recent years.

Here’s what in this guide:

In October 2013, Siemens was rebranded as Unify/Siemens. As it was changing hands, Siemens also announced that its telecommunication products would reach the End of Life.

This meant they would not be manufacturing any more phones after April 2017.

Today the name Unify takes over what used to be Siemens, and it has been a part of Atos since 2016. But that doesn’t mean there are no more Siemens telephone systems out there, or that they might be a smart choice for your business.

While Siemens no longer manufacture phones, they have stocked countless distributors with their products.

Siemens phones are appreciated for their design and durability, and with ongoing support from a distributor, investing in a Siemens phone system still makes sense.

First up, you will see what Siemens have on offer:

Siemens Core product offerings

Newer mode Unify/Siemens phones use the latest technology.

But many companies love the older model Siemens phones too, as they are durable and easy to use.

Keeping this in mind, you will read about both the popular older models and the modern Unify/Siemens phones.


First up are the Siemens switchboard or PBX products.

These nifty units work to manage all your incoming and outgoing calls.

They turn the limited number of phone lines you have into extensions for all your staff and make it easy for them to call each other quickly.

A PBX can also offer a range of tools to help you maintain a professional image, like a digital operator and call delegation.

Siemens Customer support

Since Siemens has moved away from the phone market, your sales and customer support will come from your distributor.

This works in your favour because once you have selected the Siemens product that you want, you still get some choice in who you buy it from.

You can use these reviews to find the support level to suit you.

Here are the major distributors in the UK:

Beckett Telecom

As professional engineers and technicians, Beckett Telecom is experienced with Siemens products.

They are specialists in setting up and installing Siemens systems and then maintaining them at peak condition.

They also handle the distribution of Siemens products.

You can buy your whole system from Beckett Telecom, or just individual parts.

Beckett Telecom can supply both within the UK and overseas.

MF Communications

Working alongside Siemens and now Unify for 15 years, MF Communications is the go-to the distributor for Siemens phones.

They not only install and maintain systems but are also available to support all Siemens customers.

Whether you are looking to expand or upgrade, MF Communications can upgrade your Siemens phone system to a powerful new Unify system, or scale up your existing system to achieve the aims you are looking for.

Last but not least!


As of 2013 Unify has taken over all of Siemens Phone systems and operations.

This extends to manufacturing and distribution of new PBX units.

They offer a 24-hour support service and a team of maintenance mechanics ready to fix any issues quickly.

Unity also offers you a clever Expert Wiki, where you can find all product manuals and expert answers to user questions.

Buying from Unity gives you full access to their compiled knowledge on telephone systems and years of expertise.

In case you want to get to know your phone system really, Unify has a training academy that teaches the nitty gritty details of how to best use their phone systems.

Unify/Siemens Contracts

Unify/Siemens has qualified distribution partners around the UK and the world. Your installation fees and service agreement will depend on your distributor.

You can buy Siemens / Unity products outright from a distributor, without an ongoing contract if you wish.

Alternatively, Unify offers the OpenScape pay as you go managed service which includes PBX and handset products.

With this option you will not have to make a significant investment upfront, you can add or remove services as you go.

You will also have ongoing support from Unity.

But keep in mind that as you need to keep paying for your system every month, it might be cheaper, in the long run, to purchase your system outright.

This is how the pay as you go system operates:

  • On the 16th of every month, Unify/Siemens will send a monthly report to your nearest distributor so you can keep tabs on your monthly usage.
  • On the 25th of each month, you will get an invoice for all your cost and fees for that month, so you know your exact billing.

Unify/Siemens Customer reputation

According to Gartner Peer Insights Unify has an overall rating of 3.6 stars out of 5.

Users like using the product and find it reliable. Desk handsets and the call centre capabilities were particularly praised.

Some users commented on the changes in the support team as Siemens support moved to Unify, but help from both sides was found to be of a high standard.

The main issues that reviewers pointed to were:

  • Customer support is mostly through remote communications (via phone, email and instant message)
  • Very cost effective but primary offerings are not outstanding and have some design flaws
  • Unified Communications gets mixed reviews; some users state that it needs further development, others find it too advanced for users that are happy with more traditional desk phones

These views are very subjective, and your experience will depend on the needs of your business and how advanced you want your system to be.

The systems are compatible so you can easily work with Unify to expand on your current network.

This will save significant cost as you can use the hardware you already have.

Your expanded system will be a modern hybrid that supports both IP-based and traditional line based equipment.

If you are looking for a new system, your best bet will be to work with Unity to install one of their state of the art PX and handset systems.

They will be a great choice, especially if you think a unified voice and digital system could make your business run more smoothly.

Their OpenScape services will be a great option for call centres, remote offices and businesses that need a lot of team collaboration to operate at their best.

Final verdict

Siemens business phones have long been a global staple in the business phone market.

Past models were key to connecting massive enterprises together.

In the more recent times, Unify/Siemens has focused more on hybrid systems and are producing models that are more compact for small to medium-sized businesses.

You are already on the right path if you currently own a Siemens HiPath phone system.

You will not have a problem with service or supply as Siemens still has global distributors.

Even if you wish to upgrade, you can expand on your system at low cost to achieve maximum effectiveness by working wit Unify.

This will give you a fresh and modern system at a cost-conscious price.

If you are looking for a new system, then the range listed here will be a great starting point.

You can work directly with Unity to create a package that will help your business collaborate and grow.
