VoIP Telephone Systems in SME & Holdings

Do businesses really need to move to VoIP Telephone Systems when we can use Smartphones and Messenger bots? Let's be realistic! The current situation of providers switching off their ISDN Technology is a reality all medium to large companies across Europe are now having to deal with. The pandemic and brexit have caused enough suffering in Europe.

So if you are used to sending a fax to your clients, suppliers or contacts even outside your country? Then you are in for a nasty surprise. Providers are also getting rid of fax services. They hate this stone age technology. You must admit, nobody has been infected by a fax. Plenty of emails come into company systems with very destructive viruses and ransomware. A fax is just a sheet of printed paper. That fax will not bite you.

Wouldn't it be nice to solve these pains mentioned above and improve your way of making phone calls at the same time? 

Using virtual phone systems you get the best from modern VoIP Telecommunication. Besides, even if you decide to move your busines to a new location, or do get bitten, you can continue working from your home office. Even flooding can not hurt your VoIP PBX, as it is safely tucked away in the cloud. You can use it on the road, too! Install the phone app on your iPhone or Android. You can make calls with the car's hand free speaker system. If the pub is quiet you can even make a call from there, as nobody would notice the difference. 

Hey, don't walk away! You do not need to be a huge corporation to use such a phone system. Our flexible plans allow you to scale as your business changes.
