The ISDN decline and worthy replacement options.
The decline of ISDN
BT has given Integrated Services Digital Network (ISDN) users up to 2025 when the services will be terminated after decades of application across many businesses in the UK. ISDN was introduced as a channel for the digital transmission of services such as voice and video over Public Switched Telephone Network (PSTN) simultaneously. ISDN switch off will put it into retirement with subsequent migration of customers to an IP network. With the increased need for flexibility, ISDN experienced a sharp decline in the UK where the number of channels reduced from 4.7 to 2.7 million between 2007 and 2012, there are still thousands of ISDN circuits still in use even today.
Why is ISDN expected to be phased out?
Despite being applauded upon its introduction, ISDN will finally come to an end in the next few years following a slow decline. The upcoming ISDN switch-off is attributed to obsolesce. The legacy systems have been rendered out-of-date by better options that are faster with lower running and maintenance costs. The lines have barely improved in design, which ensured that ISDN could not keep up with the fast-paced technological advancements in other fields. Mobile phone proliferation has increased flexibility in businesses, which means that they do not have to rely on ISDN. Other factors that led to the decline are increased access to high-speed internet and remote working programs.
Options after ISDN switch off
If your business has been using ISDN, you need to prepare early before the transition by considering different replacements. There are a number of worthy replacements that you can implement to replace ISDN in your business.
Hosted VoIP (Cloud-based)
Hosted VoIP is a viable replacement option, especially for startups and small businesses that may not wish to invest in expensive phone systems. A hosted phone system will bring your company greater flexibility since it is portable and has an allowance for adding new users in case of growth. Additionally, you can regulate communication costs through the subscription-based method of billing.
Another alternative is SIP trunks, which provide better flexibility. The trunk is recommended for entities with new phone systems. The configuration enables service provision as long as there is an internet connection or leased line. Depending on your company’s circuit type, SIP trunks carry and terminate both inbound and outbound communications.
The ISDN switch off will only affect your business if you ignore the better and more cost-effective options that are already available. It is advisable to start the transition and upgrade as early as possible to avoid incurring additional charges. With the availability of many reliable replacements, it is time to seriously consider upgrading to modern technology.
