Benefits Of VoIP That You Need To Know

The new technology called Voice over Internet Protocol (VoIP) allows every user to make calls using the broadband Internet rather than the conventional or analog phone system. How VoIP works? This technology converts sound into digital voice communication and transfer it through Internet broadband. It means if you are using VoIP telephone system you are basically using the Internet to make phone calls.

What Are The Benefits That You Can Get From VoIP? Let’s find out!

Save cost

A VoIP telephone is more affordable than using a conventional phone. So if you are going to call long distance calls using VoIP, you’ll pay a much cheaper cost. You can choose PrePaid solutions if you want to minimise financial risk or if you want to ensure that you are worry free from paying higher bills with your line.


You can enjoy the convenience and comfort that a VoIP telephone system can provide because it is available all over the world. Through using broadband connection you can log in to your VoIP telephone, and you will get a dial tone. Wherever you are, if you have Internet access, problems in terms of costs and connections are no more! VoIP systems are also accessible via email or while you are traveling. Just get your headset or IP phone, and you can contact staff or clients with a low cost call.


A VoIP system allows you to acquire your own VoIP number. So even if you are traveling but you have a high speed Internet connection, you can still receive phone calls to the same number. It has full caller ID support and the best part of it, you will know who is calling before the Phone Rings. If your business is based in Australia, there is a wholesale VoIP access provider that can give you access to all Australian Local Numbers and even access to Grey Pages.


You can also conduct a voice mail through your VoIP phone apart from making calls. So it is much easier and convenient to stay in touch and give early information or reminders with your co-workers and clients to discuss important deals, affairs, meetings, files, documents, agendas, no matter where you are. If you are on abroad and you need to attend two meetings at the same time, you have the capacity to attend other important meetings in the home office without worrying missing any conference or meetings.

A quick example of the CRM + DID + Inbound Call

Here is a 40 second video demonstrating the admin CRM instantly responding to an inbound call. Once a call is received on an inbound telephone line (DID or Direct Inward Dial) the admin CRM will search the database for any existing users and display the search result in a dedicated Search Result pane. This will allow you to see whom is calling and select the appropriate account.

Calling on Our Network

There are many ways to setup a voice network, and buying cheap minutes is not one of them. Our gateways are based on TDM (Time Division Multiplexing, real physical telephone lines) networks. This means that your calls actually go through a physical line and not some voice gateway in Sweden.

This provides you with a low delay call with crystal clarity.

Our IP backbone is well connected with GigaBit connections and uses BGP4 for redundancy to multiple carriers.

We also minimise the use of un-necessary compression. Compression is used to reduce the amount of bandwidth used by a call, which in turn affects the quality. Our network also support High Definition audio.
