How to move your phone system from ISDN to SIP

by john

WHAT'S HAPPENING TO ISDN

ISDN (the Integrated Services Digital Network) is being phased out in 2019 as the NBN rollouts continue to change the Australian Telecommunications landscape. So it’s time to move your ISDN phone system to SIP. How do you move your phone system to SIP you ask, well first you need to understand what it is and how the change happens. On top of this, you will also benefit from some of SIPs other advantages in cost reductions, flexibility and redundancy.

So WHAT IS SIP?

SIP by definition is Session Initiation Protocol. This is a method upon which the phone calls you make are delivered across internet and data network. These calls are effectively translated from one technology to another so that a call from a data network can be delivered to a fixed line PSTN network or to a mobile network across what the telco industry refers to as a SIP Trunk. SIP is made up of 2 basic components being the TRUNK – think of this as the infrastructure or a pipe that the calls flow through. The other component is the CHANNELS – the number of concurrent calls that are allowed to flow though the trunk. SIP trunks also allow other forms of data to travel through them such as video. But for the sake of voice – it is the technology most of us know as VoIP (Voice over Internet Protocol)

WHAT TECHNOLOGY IS NEEDED TO HAVE A GOOD SIP / VOIP CALL?

Good Internet:

Keeping it simple, the answer is a good internet connection.
This is the biggest question we get: Will SIP and VoIP be as good as ISDN? Will it be as reliable? The answer is that SIP and VoIP have come a long way and it is all about the way it is delivered that makes it a success.

An ISDN to SIP migration requires that you have a good internet connection and SIP needs its own space in the network to perform its duty. Good quality calls without crackle, hiss or garbling are produced by giving the voice traffic in your network the highest priority.

Services such as the NBN have made it possible for everyone to have an internet connection good enough to handle the voice traffic and provide quality communications. And where in some cases the NBN has not been good enough, there are alternative internet connections that can be put in place to run Voice only.

An integration Path to you Phone System:

The next thing is connecting from the internet to your phone systems. YOU DO NOT NEED A NEW PHONE SYSTEM TO DO THIS! Many unscrupulous or plainly inexperienced sales people lead many customer to believe that their phone system will not work on SIP or the NBN. This is a lie.

Your phone system just needs a way to speak the SIP language. Many existing systems have the capability already built in. Others just need a translation device. These translation devices are known as ATA’s. An ATA is an Analogue Telephone Adapter. It takes the SIP communication and converts it back to an analogue transmission so that you can have a simple way to move you old technology to SIP.

Here’s an example: Joes Transport has a phone system with 4 PSTN lines. Joe’s moving to the NBN and will be loosing all his PSTN lines in the process. Com2 work with Joe and see that he is hapy with is current phones, they all still work, there is no need to change them so Com2 specify an ATA with 4 Channels to replace the 4 PSTN lines. The cost to do this? Simply the labour to migrate from one technology to the other.
