In 2015 BT announced that is was phasing out its PSTN and ISDN networks, that are used for voice calls, in favour of more advanced IP voice services. This gradual phasing out of the older PSTN and ISDN systems is due to start in 2020, when BT will cease taking any more ISDN orders, leading up to 2025, the proposed date of the ISDN Switch off.
If your business makes use of or provides PSTN or ISDN lines or networks, then this switch off is going to have a significant effect on you. By 2025, businesses will be forced to find and use an IP-based system for all of their telephony needs.
ISDN (Integrated Services Digital Network) is a telephone network that allows for both voice and data services to be delivered over digital lines simultaneously. Effectively it’s what carries your telephone conversations when you talk on the phone and your data when you use the internet. It was launched in 1986 to migrate old landline technology over to digital.
ISDN was a great system when it was launched as it could support an analogue phone line and early video-conferencing systems, something extremely useful for businesses at the time.
Unfortunately for ISDN, the introduction of new broadband internet access connections has made it an outdated legacy system. It is still used by many smaller businesses or as a backup phone system in the event the main line fails.
PSTN (Public Switched Telephone Network) is the familiar landline telephone system that has been used since the invention of the telephone. It was set up for analogue voice communication and was the most reliable way of making voice calls. ISDN allowed the digital transmission of voice and video using the traditional PSTN network.
VoIP (Voice over Internet Protocol) technology has transformed traditional telephone services, superseding ISDN systems with cheaper, more advanced solutions. VoIP is the method of making phone calls over the internet or an internal network. Also known as an internet telephone, the use of this method of communication has become mainstream, removing the need for an old-fashioned and expensive to maintain phone lines at your premises.
Cost-effective (free and cheaper calls, plus no more expensive line rental)
Better features and flexibility (integration, greater control and analytics that transform your business communication)
Higher resiliency (stay connected, ensuring business agility and productivity)
Greater flexibility (plug into your network from anywhere with Wi-Fi)
SIP (Session initiation protocol) and SIP trunks is an on-premise solution for a telephone system that allows you to connect your phone system to the public phone network via IP data services rather than traditional fixed line telephone services, such as PSTN and ISDN. SIP offers improved scalability and functionality through a single internet connection which allows you to divide bandwidth between voice calls and data. Being 30-50% cheaper than traditional telephone lines, SIP is a popular choice.
SIP connectivity is now standard on most modern phone systems and available as a simple upgrade to legacy systems. This allows you to maintain your investment on your existing system and still benefit from the flexibility and cost-savings of SIP services.
Reduced costs (SIP includes free landline calls and other lower priced options)
Scalability (individual SIP endpoint connections can scale from 2 to 30 channels)
Business continuity and reliability (Criterion Networks provide dedicated servers for your phone system to connect to as well as running carrier-grade software for superior reliability)
