How to prepare for the end of ISDN.

Planning for the ISDN phase out

With the announcement by British Telecom to stop support for ISDN services by 2020 and complete cessation by 2025, it is vital that businesses plan a migration policy as soon as possible.

The future-ready solution is SIP. SIP is a ready-made replacement for ISDN, connecting a business’s telephone system to the national network via broadband, ethernet or a private circuit.

SIP trunks emerged through a growing need for reliable, flexible and scalable communications technology that enables growing businesses to manage communications effectively in line with demand and is already prepared for voice and data convergence further down the line.

Moving from ISDN to SIP.

We indicate below some of the key steps, we beleive you need to take to effect a changeover.

Step one: scoping the job

The Avandda team can help you establish what the move will look like for your business. This may be a wholesale switch in one move, a phased branch by branch transition, or even floor by floor. SIP can work alongside ISDN, so the switch needn’t be fraught with the panic of turning one system off and another on at the same time. Costing will also be included within this part of the process.

During this period there should be little or no disturbance to your business. And any tests or checks can be carried out in a controlled environment.

Step two: audit the current system

A big part of the process from our end will be auditing your current infrastructure and network capacity. Essentially, we need this information in order to understand the optimum service provision required to meet your business demands.

This can include the available bandwidth on the existing data connectivity, to decide if additional or dedicated connections are required to carry voice traffic. As with any audit, it will be a case of check and check again to ensure everything is accounted for. Avandda offers the audit free of charge.

Step Three: switch and go live

Time to switch your service to your new SIP. You do not need to worry about downtime as our network service team will divert calls to any requested mobile or landline during the switching period. The important thing is to note that if steps one and two have been completed correctly, step three should go smoothly.

For modern businesses, there is no longer a good reason to continue working with an ISDN-based telecommunications solution.

With the cost saving potential of SIP trunking, as well as its resilience and reliability, it is the common sense option for any organisation looking to be truly always on and to provide customers with a first class experience.
