Why PSTN/ISDN customers are switching to VoIP and why they’re not

Earlier technology, PSTN (Public Switched Telephone Network) is the standard telephony set up for small businesses, with ISDN (Intergrated Services Digital Network) delivering digital lines for larger businesses. Thanks to bigger and better data capabilities, businesses are now embracing VoIP, aka the “Voice Over Internet Protocol” – the flexible phone system that allows you to make calls over your internet connection.

Why are businesses moving to VoIP?

VoIP has the ability to cut monthly costs associated with multiple PSTN/ISDN lines, as a VoIP system requires just one line with an internet connection. Only a single network is needed to carry both your voice and data, whilst storage space and equipment costs associated with traditional systems are diminished. Scaling up or down is easy, you can add a line as soon as you add a new employee, and when an employee leaves, you can easily reassign or remove the line. Ensuring you always have the right number of phone lines for your needs. In contrast, ISDN can hinder growth plans and/or adjustments to staff turnover as it cannot be easily expanded to accommodate for new users and carries the costs of installation and downtime if you choose to move offices.

With VoIP, you can take advantage of inexpensive international calls and long distance calls and gain the ability to make and receive calls anywhere with an internet (or 3G/4G) connection. This dramatically increases your flexibility and addresses the issue of ‘service interruptions’ better than any traditional PSTN or ISDN solution could.

Why would a business stick to PSTN/ISDN?

Having voice and data on one connection can also be problematic if the implementation has not been scoped properly. If there’s not enough bandwidth available, for example, then your call quality could be very poor, making calls extremely difficult to understand and, of course, having a negative impact on your brand.  However, Voice can be prioritised over data traffic and concerns over poor call quality are therefore due to poor implementation rather than the technology itself and can be solved by using an experienced telecoms provider with VoIP expertise. Secondly, when VoIP first arrived, it was a time of dial-up connections and VoIP was associated with poor audio quality and dropped calls. In light of the increased availability of broadband Ethernet services, however, this is no longer a problem and VoIP is often the most popular option, despite the misconception still held by some businesses.

The future of telephony

In line with current progressions in VoIP technology, the British Multinational Telecommunications giant, BT, will switch off ISDN lines in 2025, with purchases discontinued as of 2020. In light of the upcoming switch off, we are offering a free VoIP system for customers who choose CMM to progress to VoIP*.

Fewer than half of consumers are taking advantage of the broadband speeds available – are you?

Communication is at the heart of every business. Ensuring you can sell your goods and services, connect to your customers, deal with suppliers and manage your workforce. At CMM, we understand reliable and high quality broadband and mobile connections are vital for our customers to successfully run their business, and for some digital enterprises, actually deliver their services or products.

In January 2018, the government announced it had hit it’s connectivity target, with 10 out of 20 households and businesses now with access to ultrafast broadband connectivity. Yet only 38 percent of the population are taking advantage of the superfast broadband available to them, with the majority still using ADSL lines without feeling the need to upgrade (Ofcom).

Just 38% of the population are taking advantage of superfast broadband

We offer a variety of connectivity solutions, ranging from ADSL to private circuits, to ensure you receive a tailored plan that will optimise your telecoms infrastructure, according to your budget and needs. Most importantly, we want you to be aware of the newer technology that is available, to ensure your business is benefiting from recent advances and running as productively as possible.

Are you due an upgrade?

To determine whether opting for an upgraded solution would benefit you, you may wish to consider the following:

  1. Do you use your broadband at the same time as other people in your office or site?
  2. Download large online files on a regular basis?
  3. Upload videos and other large files to the web?
  4. Use Cloud or video-calling services such as Skype?
  5. Offer Wi-Fi to customers?
  6. Rely on the internet as a vital tool to run your business?

Alternatively, you can read our quick guide below about the recommended solutions for different business needs.


ADSL operates on a standard analogue phone line to your premises, to offer speedy and secure internet access. Although download and uploads speeds are a long way behind Fibre to the Cabinet, ADSL is suitable for businesses that are unable to receive FTTC internet or that just need the internet as a basic tool for activities such emailing, placing orders online or blogging.

✓ Ideal for small business’s looking for a cost-effective, basic use solution.

Fibre to the Cabinet:

FTTC involves running fibre optic cables from the telephone exchange or distribution point to the street cabinets which then connect to a standard phone line to provide broadband. This is combined with a copper cable from the cabinet to the business that can deliver much faster speeds over shorter distances. Benefits include file download and upload in seconds, improving the use of multi-media and conferencing facilities. Along with increased productivity with no delay’s online, FTTC can also lower call costs by taking advantage of VoIP delivered over Fibre.

✓ Ideal for business’s requiring a fast connection to the internet or services such as video conferencing, IP Voice and Cloud services.

Leased Lines/Private Circuits:

A Leased Line is a dedicated connection to the internet with guaranteed upload and download speeds, SLAs and an uncontended connection. This means that your internet speeds won’t be affected by your neighbours usage. Although still relatively expensive compared to FTTC, prices for your own dedicated connection have reduced dramatically in recent times. There are many different variants of private connection, which we would be happy to talk through with you.

✓ Ideal for businesses requiring a fast connection with guaranteed speeds, and quick response times for faults.

How to keep your device protected against Meltdown and Spectre

Panic over the security holes named ‘Meltdown’ and ‘Spectre’ that have the potential to affect devices powered by Intel, AMD or AMD processors has been widespread. These chips speed up your device’s performance by assuming what you’ll do next, based on previous usage, to execute the action in advance. The ‘hole’ is that hackers could use this common feature to steal private data such as passwords.

These security issues apply to all modern processors and unfortunately affect nearly all computing devices and operating systems. The good news? Apple, Google, Intel and Microsoft have confirmed that there have been no known cases of either Meltdown or Spectre impacting customers.

Image result for meltdown spectre

“All Mac systems and iOS devices are affected, but there are no known exploits impacting customers at this time.” – Apple

 “We have not received any information to indicate that these vulnerabilities has been used to attack our customers.” – Microsoft

Since learning of the security issues, industry leaders have been working hard to overcome the potential loopholes. For customer protection, information of Meltdown and Spectre was kept under wraps until preventative measures were available to avoid giving hackers a roadmap. So far, Intel has issued updates for nearly 90% of processor products introduced within the past five years, but a timetable for older devices is yet to be confirmed.

How to stay protected – Apple users

Apple has released a software update to help protect users from Spectre and Meltdown. We highly recommend you update your devices as soon as possible. Here’s how…

  • On iOS, go to Settings, General then Software Update, then tap Download and Install.
  • On MacOS, open the App Store and click Updates in the App Store toolbar, then use the Update buttons to download and install any updates listed.
  • On Apple TV, go to Settings, System, then Software Updates. Select Update Software, then select Download and Install. After the update downloads, your Apple TV will restart and prepare the update.
  • Apple watch is not affected by the issue.

It is also recommended that any apps are only downloaded from the iOS App store, from trusted sources.

How to stay protected – Android users

On January 5th 2018, Google issued an update to protect Android devices. All Google-branded phones should have automatically downloaded the update so you just need to install it. For other Android devices, head to Settings. Scroll to the bottom of the menu and tap ‘About device‘ > ‘System updates‘ > ‘Check for update‘ > Tap ‘OK‘ if asked to confirm > Wait for your device to check for updates > Tap ‘Download‘ or ‘Yes‘ if an update is available.

Google Chrome

The patch for Chrome will be installed on January 23rd and some Chromebooks had a mitigation in its OS 63, released in December. If you do not want to wait, an experimental feature from Google called Site Isolation can help in the meantime. This feature makes it harder for malicious websites to access data from other websites you are looking at. To use this feature on Windows, Mac, Linux, Chrome OS or Android copy and paste chrome://flags/#enable-site-per-process into the URL in Chrome. Click ‘Strict Site Isolation‘ and then press ‘Enable‘. Save your work and then press ‘Relaunch now‘.

Microsoft Windows 10

There is already a patch available for Windows 10 which will automatically be applied, a patch for older operating systems will follow shortly.

Cloud Services

Major cloud services aimed at business customers, including Amazon Web Services, Google Cloud Platform and Microsoft Azure have already been patched.

Please note

It’s also worth remembering that you’re safe unless hackers can infiltrate your system, so always be wary of unexpected emails or clicking links on pop-up webpages. We recommend you check all your devices for security updates and install them as soon as possible.  We understand you may have concerns, if you have any questions or need support updating your software, you can get in touch via, call us on 01252 854352 or send us a message on live chat. We are always more than happy to help!

Apple clarifies iPhone battery deterioration rumours

Apple clarifies iPhone battery deterioration rumours

Apple has addressed concerns that some models of the iPhone slow down as they age. The renowned mobile giant was accused of deliberately slowing down older devices to encourage consumers to upgrade. Apple has confirmed that it does in fact slow down some models as they age, but only because the phones’ battery performance diminishes over time.

“First and foremost, we have never — and would never — do anything to intentionally shorten the life of any Apple product, or degrade the user experience to drive customer upgrades. Our goal has always been to create products that our customers love, and making iPhones last as long as possible is an important part of that.”

All rechargeable batteries, including the iPhone batteries are consumable components that become less effective as they chemically age and their ability to hold a charge diminishes over time. A chemically aged battery also becomes less capable of delivering peak energy loads, especially in a low state of charge, which may result in a device unexpectedly shutting itself down in some situations.

Image result for apple iphone battery 6

To avoid shutdowns on the iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, and iPhone SE, Apple delivered a software update – 10.2.1. With the update, iOS dynamically manages the maximum performance of some system components when needed to prevent a shutdown. While these changes may go unnoticed, in some cases users may experience longer launch times for apps and other reductions in performance.

Over the fall, Apple received feedback from users who were seeing slower performance, they now believe the continued chemical aging of the batteries in older iPhone 6 and iPhone 6S devices contributed to this.

To address customer concerns, Apple has reduced the price of an out-of-warranty iPhone battery replacement by £54 – from £79 to £25 for anyone with an iPhone 6 or later, whose battery needs to be replaced, until December 2018. Apple will also issue an iOS update with new features that will offer more visibility into the health of your iPhone battery so you can monitor if its condition is affecting performance.

How to charge your smartphone quicker

How to charge your smartphone quicker

Realising you’re running out of juice can cause a panic when you’re short on time and in a rush to head out. Here’s how to optimise charging time:

1) Set your phone to Airplane mode

Cellular, Bluetooth radio and WiFi services zap your power in the background, even when your device is not being used. Airplane mode shuts off these connections and speeds up the charging process. You can turn on Airplane mode by heading to Settings > Airplane mode. Slide the toggle to On and a small Airplane icon will appear on the top of your phone’s display. For Android devices, you can also swipe the notification panel down to reveal and select the Airplane icon. For iOS devices, swipe up from the bottom of the screen (For iPhone X users – swipe down from the upper-right corner of the screen).

2) Dim the lights

If you still want to receive texts and calls whilst charging, Airplane mode may not be the best option for you. In this case, we recommend lowering the screen brightness.  The less energy your phone needs for visual effects the faster it will charge. For iOS devices, you can swipe up from the bottom edge of your display, (iPhone X – swipe down from the top-right corner of the display) then drag the brightness bar to adjust.  For Android devices, you’ll need to head to Settings > Display> Brightness & Wallpaper and switch off auto-brightness. Once switched off, you can drag the slider to adjust your preferred brightness.

3) Make a smart investment

Finally, if your device is compatible with quick charging accessories, there’s no harm in using a helping hand to get the job done. Newer Android devices support extra-fast charging which allows for more power without damaging the battery. For example the HTC Rapid Charger 2.0 offers 40% faster charging than standard chargers for the HTC One A9, HTC One M9, HTC One M8, HTC One Remix, HTC One E8 and the HTC Desire Eye models. While Samsung’s Fast Charge Wireless Charging Pad will reduce total charging time from 0-100% by up to 50 minutes for the Galaxy Note 5 and Galaxy S6 Edge+ devices.

For Apple users, only the latest iPhone 8, 8 Plus and iPhone X devices are capable of quick charging. Unfortunately, the included standard Lightning cable and iPhone charger will not deliver a faster charge. To use this feature, you’ll need to purchase additional accessories that are compatible with USB Type-C charging, setting you back £74 (£25 for the adaptor cable and from £49 for the USB-C charger). Although a significant amount, you will be able to charge your device to 50% in just 30 minutes, saving you time and stress when in a hurry!
