How To Move Your Business From Isdn To Sip

ISDN (the Integrated Services Digital Network) will be retired in 2019 with the arrival of the National Broadband Network (NBN), so it’s time to move to a SIP network to avoid issues down the track. Like most upgrades, this is about streamlining what your organisation uses into a more unified infrastructure with cost efficiencies.

But first, what exactly is SIP?

SIP, or Session Initiation Protocol, is technology that facilitates calls over data networks to other SIP users or into the public switched telephone network (PSTN). When talking about it, you’ll typically hear the term ‘SIP trunking’ which is a direct connection between your business and an Internet telephony service provider (ITSP). Most notably, this connection allows for Voice over Internet Protocol (VoIP), making video conferencing a simple step to move to when you are ready.

The good news is that SIP is now becoming more reliable than ISDN, according to a recent column on It comes with benefits of greater speed, versatility and portability, which is why telco firms around the world are leading the switch.

Technology changes can be tricky but also come with plenty of opportunity for business. For instance, a move to SIP will rationalise your communications into a single platform and interface, and that’s always an attractive proposition.

Here are 3 easy steps to help your move to SIP:

1.Review to renew

As with all technology migrations, your business needs to take stock of its existing IT. A review can simply start with understanding the day-to-day workflow of your business. For example, how does your staff access data? How are incoming calls directed? How is your phone system actually set up? And, how does your messaging work?

In short, consider what hardware your team is working with right now and if it needs an upgrade. Keep in mind that older PBXs might function with SIP, but your business could be better off with IP phones to access advanced IP Telephony features. Would your business benefit from cloud-IVR, or voicemail to email capability. It all depends on your business goals.

2.Talk to an expert

Moving to SIP will require some business disruption, so call on some expert advice to guide you through the new technology to smooth your migration.

Solutions Consultant at Vocus, Emil Gharibadeh says that planning the change is essential because you don’t want downtime that leads to a poor experience for your customers.

“It’s important to think ahead,” says Emil. “If your review shows your business can support the migration to SIP, that’s great. You can put a plan in place. Lean on the previous experience of your telephony provider to get you where you need to be, faster and without any fuss.”

3.Choose the right network

Your network is the glue, so it’s also crucial that your business is connected in a way that meets its goals. SIP presents an opportunity to make this happen – to revolutionise your communications with a more flexible, scalable technology that offers immediate benefits.

Of course, you’ll need a network provider that’s a good fit for your business. The right team needs to be accountable to not only port your numbers over to a new service, but ensure the ongoing delivery of secure and reliable services for your staff and customers.

If your phone stops ringing, you need to be able to contact your provider and know they have the control to sort out your issue.
