Threat of ISDN shutdown already causing delays across the industry

Delivery timeframes for number porting and fibre service installation have already increased drastically in the lead-up to ISDN shutdown commencing.

With the shutdown of ISDN services to commence at the end of September 2019, the death of traditional telephony is just around the corner. The roll-out of NBN, while incomplete, has been the catalyst for Telstra to pull support for the legacy fixed-line technology, and the flood of change requests has well and truly commenced.

Number Porting

A major change for organisations shifting from ISDN phone services to business VoIP is the requirement to convert their existing phone numbers to be virtually hosted. This is achieved by porting these numbers to a new VoIP provider to ensure they aren’t lost when ISDN services are disconnected.

Delays in porting numbers are already noticeable and substantial, with average porting timeframes doubled in the past 6 months when transferring away from Telstra, and increased over 50% from Optus and other carriers. These delays are impacting all number porting, not just transitions from ISDN, and is only expected to get worse as fixed-line telephony shutdown becomes a reality.

Handling the delays:

  • Planning ahead is paramount. With complex number porting often taking as long as three months to finalise, getting ports underway early is the best way to ensure you don’t miss any calls. Over the Wire customers get access to our powerful self-service Customer Portal and easy-to-use number porting tool, and of course our friendly staff are always happy to help simplify the process for you.
  • While waiting for number ports to be completed, a redirection to temporary numbers can help to keep services flowing and give you the ability to take advantage of your new VoIP setup sooner. Ask our sales team if you qualify for free temporary numbers to help make your transition to Over the Wire even smoother than ever.

Fibre Service Provisioning

In addition to the delays in number porting, the extra demand for high speed fibre internet and private network services has also caused longer than usual provisioning timeframes for these services. Whether as a necessity due to copper-based connections no longer being serviceable, or businesses taking advantage of great new pricing for additional bandwidth options to support over-the-top voice services, the spike in requests has been noticeable. While typical lead times for fibre services is between 4 – 8 weeks, the current trend is generally between 8 – 14 weeks.
