What is VoIP?

Voice Over Internet Protocol (VoIP) can also be referred to as IP telephony, Internet telephony, Hosted telephony or cloud-based telephony. In simple terms, it is a phone that sends and receives calls over an internet connection rather that a traditional telephone line.
With the switching off of ISDN fast approaching and the increase of agile working, anyone left using a legacy PBX face big decisions. Here are some of the advantages we have found by using VoIP at 4s Systems.


VoIP offers a cost-effective alternative to regular phone systems. With most contracts, you will have the option of call packages that include unlimited minutes to local, national and UK mobiles. Some providers will also subsidise the cost of handsets or headsets when setting up VoIP.


Unlike a legacy telephone system, VoIP does not have geographic constraints meaning that you will be able to take your phone number with you wherever you go. Cloud-based telephony is just as easy as having your emails on your mobile phone so employees who work remotely can upkeep levels of productivity, allowing for improved business efficiency and flexibility.


Users can be easily added or removed to your network as and when required so you will only pay for the number of users you have. This makes VoIP an easy decision for companies who would prefer a phone system that has the capability to grow with their business.

Sound Quality

With the correct internet connection and network setup, voice quality issues and reliability are a thing of the past. The sound quality is even better when compared to regular telephone calls.
Other advantages of VoIP include the large range of functionality it offers as standard, such as call forwarding, call recording, auto attendant and call transfer to name a few. These functions are designed with business users in mind and all have low setup costs. The flexibility of VoIP is one of the key factors to 4s Systems operating our own support desk seamlessly over the Covid 19 lockdown period.
