The End Of An Era: BT To Switch Off ISDN Lines

The End Of An Era: BT To Switch Off ISDN Lines

Date: 5th October 2018 | By: admin

BT have announced their plans to migrate all customers to an IP network by 2025, switching off the company’s ISDN network. As the leading business communications provider, this change will affect millions of businesses across the UK.

Even though SIP technology has been available for 15 years; many organisations still prefer to use ISDN lines. As of August 2013; there were around 3.2 million active ISDN lines in the UK however, by 2025 all organisations will have to move to a SIP service.

Although 10 years may seem as a long period of time, we believe that the migration process will begin soon, that is why you should start learning more about SIP technology and its advantages.

What is SIP trunking?

SIP trunking is the latest form of technology that delivers telephone lines using an external data connection as the bearer for the purpose of making and receiving calls. This virtual IP based service uses network data connectivity instead of dedicated fixed line technology methods.

What are the benefits?

1. Number Portability
Using SIP trunks allows you to keep your phone number no matter where you are, because your phone number is attached to an IP address not a physical telephone line. It permits out-of-area geographic number ranges to be used – displaying your organisation as local, despite being physically located elsewhere.

2. Saves You Money
With traditional ISDN your voice and data connection are on different lines. You will be able to save money by having both on one line. SIP trunking can reduce your costs by 50% on line rentals and 25% on calls.

3. Greater Flexibility
SIP trunking gives you complete control of your lines – you can add additional trunks when demand is high, reduce them when demand is low and split calls to make handling more effective. Being able to make these instant changes will help you to remain in total control of your communications.

4. Disaster Recovery
Incidents that cause an interruption to service such as hostile weather, power failures and natural disasters, can have a detrimental impact on your business reputation. This can lead to an abrupt decline in customer retention and loyalty. SIP trunking can ensure you maintain business as usual and will be able to continue working through every eventuality.
