SIP it up

In the next few years, expect to hear a lot more about the benefits of SIP (Session Initiated Protocol) trunks for your business needs as ISDN is phased out by 2022. Naturally, you’ll be wanting to know more about delivering SIP trunks over your End to End (E2E) managed NBN and how it all works.

Lots to recommend it

To those businesses who are just beginning to get their heads around SIP trunks, what it is, it’s a digital phone line delivered over the internet. It is effectively a replacement of old phone lines.

On a practical level there is a lot to recommend it, including that it’s not just for telephone calls, SIP trunks also delivers data and video.

SIP trunks is a service which allows companies to connect their onsite IP PABX (phone system) to the Internet Telephony Service Provider (ITSP) and use its services.

A few other points about delivering SIP trunks over (E2E) managed NBN and how it all works:

  • A SIP trunk service can be delivered over (E2E) managed NBN via public internet as well as via private IP connections.
  • A SIP trunk needs to connect to a PABX – a device that provides the brains behind the phone system that enables multiple users to share lines. You will need to decide whether to host your PABX in the cloud or at your business premises.
  • SIP trunks are a versatile option as it can be scaled to your organisation’s specific needs, depending on whether you’re a big or small outfit.

Delivered over the internet

SIP trunks work by turning voice or video communication into blocks or packets of data so it can be delivered over the internet. As the call is not “travelling” through a traditional network, the call rates are likely to be lower than your current costs. It’s an attractive proposition for your business because it will be a step towards getting you NBN-ready (experts say SIP trunks is a symbol of the new era of global communications and will soon be embraced as the norm) as well as a way of cutting your business costs. 

What to consider

  • Does your business need a PABX or Unified Communications platform?
  • Your company will need to examine if and when to combine SIP trunks with your NBN or other internet service.
  • Work out how much capacity you think you will need, and also decide whether you want to keep your existing phone numbers.
