There are a lot of good reasons to switch to cloud-based VoIP communications. UK VoIP providers offer several benefits; however, they still face certain limitations. Some of the limitations you’ll face as a VolP user could be security breaches or internet dependency. In this article, we aim to weigh the limitations as well as the pros and cons of UK VoIP service providers. Read below.

Limitations for VoIP phones

1. Poor Sound and Video Quality

This is one of the most common VoIP limitations, and it occurs as a result of different factors. Firstly, if there is a great deal of traffic or a large number of people using the same bandwidth as yours, it could pose a limitation. On the other hand, the compressing and decompressing processes coupled with signal conversion on the IP network could cause VoIP drawbacks. A lot of Skype users have expressed their dissatisfaction over the “dropped calls’ which occur when their smartphones are used for VoIP connection. Also, poor Internet connection could cause this issue; if you do not have a fast Internet, your VoIP will not function optimally.

2. Internet Connection Dependency

Have you come across cable VoIP or other types of topology? Whichever choice you make, VoIP will not function without a good Internet connection. VoIP stands for Voice Over Internet Protocol; therefore, it is Internet-dependent. If despite the lack of internet connection, you can still perform the normal activities with it, then it is not a VoIP. You are most likely using a traditional broadband connection. The implication is that being in a place with poor connection or having some technical issues with your Internet provider means there will be zero communication through your VoIP. 

3. Security

Numerous companies have had to face loopholes within their IP networks, and this makes them susceptible to call interception and eavesdropping. Also, adding VoIP to the network adds another layer of vulnerability since there is no secure encryption. Although hackers can exploit this vulnerability in traditional phones, they will need physical access to achieve that. Regular phones are designed to communicate through dedicated circuits controlled by the phone company. However, VoIP packets utilize the Internet closely and navigate through multiple servers and routers located at various points. Since most UK VoIP providers fail to focus on encryption, VoIP phones become almost as vulnerable as the traditional ones. This poses one of the significant disadvantages of VoIP systems.

Overcoming Limitations of VoIP Phone Providers

1. Ensure You Choose the Correct Brand

Various factors can impact on the quality of your VoIP provider. This makes maintenance an important factor for quality service delivery, so make sure you pick a brand that makes this their top priority. Also, the VoIP brand you choose should have enough memory as it affects the sound and video quality. Do your research, ask for recommendations, and assess various models. It will help you get an idea of the different features they possess, thereby aiding you in making an excellent purchase. 

2. Pick a VoIP Provider That Has Back-Up Systems in Case of Power Outages

One of the disadvantages of VoIP communication is that most UK VoIP providers have computer systems that have no backup power supply. In the event of a power outage, there will be a system downtime because the Internet and VoIP service will not be running. Big companies like ours ensure that there are backup generators to keep your devices running all the time. Although they might be a bit more expensive than the small VoIP providers, engaging their services assures you of quality always.

3. Survey Different Companies to Find out the Features They Provide

One good way of avoiding unreliable UK VoIP providers is to evaluate the reputation of the service provider you wish to purchase from. Although filtering out valid reviews from fake ones seems like a lot of work, every effort you put into research and finding a good company is worth it. An excellent factor to look at is the number of subscribers, and as a rule of thumb, a provider will have a large customer base if they are trusted to provide reliable and secure services. Also, if big brands do business with that particular provider, it means that they can be trusted and that you will most likely be making a wise choice by patronizing them.

4. Choose a Company with Strict Regulations in Maintaining Client and User Security

Like every software or web application, security should also be deemed necessary in selecting a VoIP provider. You should check for certifications like the HIPAA, FISMA, Cyber Essentials, and Privacy Shield Framework. These certifications ensure that you are protected from every threat.  Service providers must safeguard the VoIP system; however, users must ensure they follow the best endpoint security practices, usage of strong passwords as well as single sign-on authentication for your devices.

If you weighed the pros and cons of VoIP for business, you would find out that the pros outweigh the cons. They offer a dynamic, dynamic, and diverse way for customers, colleagues, and partners to communicate.          

VoIP Phones Dos and Don’ts to Increase Efficiency


1. Checking the Phone Manual and System Guide Thoroughly

Ensure you read the phone manual meticulously on the application of VoIP. If there is someone around, having a second pair of eyes wouldn’t be a bad idea. Read it aloud if you must and make sure you understand it before using the device. Using a device that you have little or no knowledge about is a bad idea. Reading manuals written in small print might be difficult, but every effort we put in is worth it.

2. Ensure All Security Systems Are in Place Before Making the Call

For every cloud-based service you wish to use, security is a must. For an Internet-based device such as a VoIP, tight security measures are critical. You should also ensure that you engage in the best security practices. Whether it’s by making sure there are secure user authentication and network configuration or by enabling end-to-end encryption in all VoIP communication and data storage, you need to be diligent in both overseeing IT management and working closely with their business VoIP provider to ensure that security requirements are being met and enforced.

Every modern VoIP service should not neglect the provision of end-to-end encryption. We recommend that you look for services that support Secure Real-Time Transport Protocol (SRTP) or Transport Layer Security (TLS) encryption and that ideally gets the job done. 

3. Monitor All VoIP Phone Call Data Both In-Bound and Out-Bound

Going for the cheapest service is not always the best choice; paying for a premium VoIP service can help you monitor your phone call data. Whether you wish to check inbound or outbound calls, a premium VoIP service has you covered. You might want to track your call lengths to be sure that you are not being overcharged, so you need to ensure that your vendor supports call data monitoring. Moreover, make sure that the encryption on your VoIP phone


e does not prevent call data tracking.

1. Not Installing the System Properly and Using Multiple LAN Cables

On the part of network deployment, a lot of organisations have a blend of handsets as well as cloud-based interfaces. Many users may only be using some VoIP or softphone mobile applications, although desk phones and conference phones may also be added to the mix of the VoIP network. Note, however, that it is important not to mix connected devices and form factors within the same network.

Do you wish to set up a voice LAN or dislike your hard-voice phones mixing on the same network as your printers and workstation? It is certainly not a good design as it will eventually cause trouble down the line. On no account should your workspace be talking to one another. VoIP phones networks are not the same as a server farm with applications talking to databases.

2. Not Following the Safety Procedures That Come With Each System

Your VoIP phone is a computing device with an Ethernet integration. As a connected endpoint, it is imperative for customers to bear in mind that it operates like every other standard device; hence, there should also be a firewall. 

Most VoIP phones feature a user interface (UI) which enables users to log in and for developers to carry out system administration on the phone. However, not every VoIP phone is designed with firmware that protects against brute-force attacks. Your email account may shut the hacker out after a few attempts, but not every VoIP phone works this way. Not setting up a firewall is similar to opening a web application and allowing anyone on the Internet to script a brute force attack and log in. 


Generally, if you know the limitations of a particular system, solving it becomes easier. In the guide above, we analysed the various limitations of some UK VoIP providers as well as some disadvantages of VoIP communications. We have put in every effort to combat the limitations stated above to ensure that you will have the best experience of our features.
