Hosted VoIP phone systems
The emergence of internet-based telephony, along with hosted technologies and unified communications, presents new opportunities to upgrade legacy systems and improve your business phone system.
The traditional telephone network in the UK, the public switched telephone network (PSTN) is being switched off in 2025. This means that all businesses will have to give their phone system a refresh, and transition to an internet-based phone system, such as Voice over Internet Protocol (VoIP). Learn more about the PSTN switch off in our content hub.
Voice over Internet Protocol (VoIP) is the modern telephony solution. Instead of using the soon-to-be redundant PSTN, VoIP runs phone calls through an internet connection. Learn more here.
Crystaline is a VoIP provider, offering a range of solutions:
Hosted VoIP services work on a per-user license arrangement, so price is determined by the number of extensions and locations a business has. Different tariffs are available that either include all domestic calls or have a call rate card. Crystaline works closely with its customers to analyse current usage and make recommendations on the most cost-efficient approach.
