Three reasons why it's time to move away from ISDN to SIP

Lindsey McGowan, Product Manager, Maintel

BT has finally stated that by 2025, all their customers will be using IP Voice. This news was announced in BT Group’s Q3 2014/15 results and undoubtedly shows that ISDN is now considered yesterday’s technology. It’s been long time coming and sets consumers of ISDN a clear target to move away.

For BT, this convergence onto the IP network will require them to migrate all of their customers off the ISDN network at some point in the next 10 years. Although this may seem like a long time with millions of ISDN lines to migrate, this is a huge project and will probably start relatively soon.

This announcement by BT Group is one of the many reasons why as a consumer of ISDN services there has never been a better time to move to SIP.

Reason one: Rationalise your lines.

  • You can scale up and down when you want, whether seasonal or short-term
  • Increase the number of SIP channels straight away, with no lengthy installation periods
  • Move location and take your numbers with you. No need for expensive call forwards
  • Much greater flexibility with SIP.

Reason two: Improve your business continuity.

  • It offers built-in business continuity, with proactively monitored services that protect your business
  • You can route your calls to any number at any site
  • Fraud management options.

Reason three: Save money.

  • You can save money on call costs and line rental
  • Benefit from lower call rates across your entire estate
  • Rationalise your estate with a centralised SIP solution which allows you to reduce your overall line requirement
  • Free internal calls and other a host of other features.
