An efficient and effective business phone line service is key to your business staying competitive and profitable. But with all the technical jargon and acronyms it can be hard to work out what is right for your business.

And while there were ISDN and PSTN phone line options to consider, a cloud phone solution is now the way to ensure your business keeps up with customer expectations, and equips your employees with the tools they need, whether in the office or working remotely.

PSTN & ISDN to be phased out soon

As the NBN network is driving a switch from copper based voice services to services that run over broadband & data services, PSTN & SDN will be phased out.

This means that traditional PSTN & ISDN users will have to switch to alternative VoIP based voice services. If you want to keep your PSTN Phone numbers, you will have no choice but to move to VoIP based service to replace your old voice lines.

Legacy PBX hardware will need to be replaced as PBX systems will need to be compatible with IP based voice services, or a cloud based phone solution.

What is the difference between ISDN and PSTN?

ISDN stands for the Integrated Services Digital Network, a digital network technology that carries and transmits voice, data, video and fax in a digital format. In Australia, ISDN services can either be a basic rate service, known as ISDN 2 or a primary rate service, known as ISDN 10/20/30.

ISDN2 (BRI – Basic Rate Interface) is the entry-level version and has two 64 kbit/s voice channels and one 16 kbit/s signalling channel that add up to 144 kbit/s.

ISDN10/20/30 (PRI – Primary Rate Interface) provides users with 10, 20 or 30, 64 kbit/s channels permitting for a maximum data rate of approximately 2 megabits per second (Mbit/s). Medium to large businesses usually use primary rate services.

PSTN stands for Public Switched Telephone Network lines. With this dedicated service, each line has a unique phone number with the area code of its assigned telephone exchange. Despite the core network being almost entirely digital, PSTN is delivered to the premises via twisted copper pairs in analogue form.

While business phone line services using PSTN are similar in function to residential landlines, they are managed on less congested networks. Even though many businesses are still using PSTN as their business phone line service, there are limitations.

If your business is growing, your office will need to have more than one PSTN line. Installing multiple PSTN lines can become very expensive.
