At some point in the near future, telecoms operators are expected to stop offering ISDN as an option. This trend was started in May 2013 when US telecoms provider Verizon stopped offering ISDN basic services to new business customers. And it’s now happening in continental Europe.
A major factor is that businesses are demanding more flexibility from their telephony system.
The message is clear; the more flexible SIP trunk is fast consigning ISDN to its ultimate demise in the business telephony market.
