SIP Phone

You might have heard people talking about an SIP Phone and have been wondering what the term refers to and how it can benefit your business.

There’s a good reason these devices have become one of the hottest topics in the telecommunications industry. They’re an excellent way to improve the quality of your phone services and expand your telecommunications offerings into multiple locations, both within Australia and across the globe.

What is an online SIP Phone?

SIP stands for Session Initiation Protocol. It’s a type of communications protocol used to integrate multimedia communications sessions.

This means that once it has been connected to your IP network, you can use your SIP phone to integrate basic telephone capabilities with web, email, online chat, and much more.

That’s why these phones are an excellent choice if you want to unify all your communications within a single platform.

SIP Phone
In a world where companies are increasingly embracing the opportunities and benefits afforded by remote working, SIP telephones are a fantastic option. As cloud-based services, they can equip your staff with the tools they need to communicate effectively with both colleagues and customers no matter where in the world they are.

What’s more, these systems can offer you significant cost savings on your communications. For these reasons, an SIP phone system is an invaluable tool if you plan to expand your operations, especially into new markets.

So if your organisation is looking for scalability, reliability, and effective communications with remote customers, clients, and employees, these phones are hard to beat.

Types of SIP Phones

There are several different types of SIP-based phones available.

Softphone / Software-Based SIP Phones

An SIP softphone isn’t actually a physical phone at all. It’s a software application installed onto your computer or smartphone that allows you to complete phone calls over the internet using the device’s in-built microphone.

If you have configured your SIP phone system to use softphones, we recommend using headsets and microphones to get the best possible calling experience.

Hardware SIP Phones

As the name suggests, these phones are actual pieces of physical hardware that look no different from any other traditional handset. They’re very similar to regular phones in how they’re used, too. However, instead of making calls through a traditional phone network, calls made by SIP hardware-based phones are routed over the internet.

These phones can use your office’s existing data network, too, which means that you won’t need to pay for extra internet service just for your phone system.

If you would like an SIP phone that offers your employees greater flexibility around the office, there are cordless models of these hardware phones available, too.

There are three main classifications of hardware SIP telephones:


These starter phones are what you might see in a call or a contact centre. They have dial pads and are capable of making internal and external calls. These budget-friendly models also offer incredible ease of use.

Intermediate SIP telephones offer more robust functionality than their basic counterparts. For example, they often include browsable directories that feature multiple extensions.

They may also have more physical buttons connected to extra features. These SIP phone models can usually be used at home, too, making them a great choice if your employees need to work remotely.


Advanced SIP-based phones are, as the name suggests, top of the line in terms of the features and functionality they offer you and your employees. They often include full-colour displays, multiple extensions, and even Wi-Fi or Bluetooth compatibility. They’re the type of phones you can expect to see on a company executive’s desk.

They are likely to have a slimmer, sleeker physical design featuring fewer buttons, as the display usually allows access to all the applications the user of the SIP phone might need.

Save Money

Because SIP-based phones route calls over the internet, they offer you significant cost savings over traditional phone networks, especially when making long-distance calls. These savings are even better when you leverage your office’s existing data network.

As its operations are conducted off online systems, an SIP phone does not require the same extensive hardware or server supplies that a traditional phone line does. This means that you will not have to pay heavy installation or maintenance costs, nor will you have to wait for a technician to come out to your office to set up or service your equipment.

If you need to make changes to your phone system (for instance, to adapt to a rapidly growing business or changing industry), the substantial ease-of-use of these phones usually means that you can make any amendments yourself, even if you do not have extensive technical knowledge.

Go Global

You’ll be able to make phone calls anywhere in the world with your SIP phone – without paying the astronomical prices traditional telcos charge for international calls.

Best of all, if your SIP provider partners with local networks in your destination country, you’ll have the option of making your call appear to be coming from a local number.

Customers prefer making calls to and receiving calls from numbers familiar to them. This means that this form of routing will help your business gain consumer trust as you enter a new market.

For these reasons, if you’re planning on taking your business global, SIP phones are an excellent tool to expand your operations with minimum capital outlay.


Some SIP phone models can integrate their systems with a wide range of other applications, including your Outlook contacts, CRM systems, and numerous mobile business apps.

This means that you’ll be able to manage a vast range of communications from a single, convenient place.

SIP applications are present in many communications products these days, including online meeting software solutions. The minimal costs of upgrading your legacy systems to an SIP-based network are well worth the numerous benefits they can offer your company.

  • Hold, with optional music
  • Conference calls
  • High-Definition phone calls
