What is VoIP?

VoIP is a general word describing conversations that happen over the internet. It stands for Voice over Internet Protocol. VoIP is commonly referred to as 'Voice over Internet' and 'Voice over broadband' as well. VoIP lowers the overheads for providers, resulting in really cheap phone calls for you, and free calls between you and other VoIP users!

Technical Stuff:
Voice over Internet Protocol, is the routing of voice conversations over the Internet or through any other IP-based network. The service we offer at Maxo Telecommunications offers a VoIP to PSTN (Public Switched Telephone Network) gateway, allowing you to dial regular PSTN numbers from your internet connection!

Maxo Telecommunications VoIP is a Voice Service Provider or VSP. With a VSP, you dont need to know the IP address of a VoIP phone to call it, you just have to know it's extension number on that VSP.

What is an Extension?

An extension is the number your SIP (internet) phone is assigned when it registers to (logs onto) the Maxo Telecommunications VoIP service. Each SIP device on Maxo Telecommunications has a unique 5 digit extension number, and you can call other Maxo Telecommunications extensions for free! (Including extensions on other people's Maxo Telecommunications accounts - so that you can ring your friends for free if they have an Maxo Telecommunications account). You can have more than one extension for example one at your house, and one at your business - you can make calls between them for free.

You can set the outgoing caller ID (CLIP) of each extension individually, or have it default to a value you select for all extensions on your account. You can also choose to divert your extension to a phone number or voicemail if it is busy or after a number of rings. Between all of the extensions on your account, the maximum number of simultaneous calls you can make or receive is governed by the number of lines that your account has.

What is a Line?

The number of Lines you choose is the number of simultaneous calls you can have active at once, incoming and outgoing.

What is a DID?

A DID (Direct InDial) number is one that exists on the PSTN (Public Switched Telephone Network) and can be connected to the Maxo Telecommunications's VoIP to PSTN gateway to allow you to receive calls through that number via your Maxo Telecommunications Extension. You can set the destination of your DID to an extension, a voicemail box, an external phone number, a fax inbox or an infoline!.

Currently Maxo Telecommunications offers DID's in all of the capital cities, and in some regional locations.

Which DID locations are available?


How reliable is VoIP?

The reliability and quality of each call you make or receive can depend on many factors. The most important is the internet connection between your VoIP phone and our gateway. If your ISP is experiencing problems or your internet has been slowed due to exceeding your quota, then your call quality may be affected. Every now and then Maxo Telecommunications will perform off-peak maintenance in the early hours of the morning which could cause your service to be offline during a maintenance session. You will be notified at least 24 hours before maintenance occurs, unless it is emergency maintenance (eg: Something has broken!).

How secure is your service?

Our website has a high grade 256 bit SSL encryption engine using our certificate from RapidSSL. We use this encryption for access to the control panel, and payment pages to ensure your information is kept secure. All credit card payments are processed by St George Bank, using a proprietary encryption protocol designed by St George Bank.

Which codecs do you allow?

  • G711 (ulaw/alaw)
  • G729
  • G726
  • G722
  • GSM
  • ILBC
Our preferred codec is G729 because it offers the highest compression and works on all internet connections, however G711 is available because it offers the highest quality speech.

What are the minimum requirements to use Maxo Telecommunications VoIP?

You need a broadband ADSL connection with a minimum speed of 256/64. If you plan to use a software based phone on your computer, you will have to check that your PC meets the minimum requirements for that software. If you are going to use an Analogue Telephone Adapter (ATA) eg SPA2000, then all you need is a broadband ADSL and you are all ready to go!

What do I need to get started?

Your broadband needs to meet the minimum requirements above, and then you will need to choose how you will connect to Maxo Telecommunications. You can use a software phone on your computer with a headset or microphone & speakers to make calls with virtually no setup cost. For more serious VoIP users, you can purchase some hardware so that you can make & receive calls without using your computer. For that you can get a VoIP phone which plugs straight into your broadband connection/computer network, or a VoIP analogue telephone adapter (ATA) which plugs straight into your broadband connection/computer network and then you plug a regular telephone (or even a cordless telephone) into the ATA. Take a look at our VoIP shop to buy hardware and for more information.

Help! How do I setup my VoIP Device?

You should go to our setup guides section to learn how to set up some of the major devices currently available on the market. It is actually quite easy to set up your VoIP device, it is usually the firewall that gives you problems, so make sure you have forwarded those ports!

Do I need a Hosted-PBX Account?

Having a Hosted-PBX account allows you to completely manage the way incoming calls work, with the ability to setup intricate call routing (Including Ring Groups, Call Queues, Time Switches ect.).

No more costly PBX system to buy - instead you simply purchase the handsets, and for less than the price of the equivalent landline rental, you can have all the features of a PBX system. You can make changes to the phone system yourself online, or call our friendly support team for assistance at no cost.

You will save heaps on your phone bill just by switching to VoIP, with untimed calls to landlines Australia wide, and per-second billing on our low mobile rates!

How do I setup voicemail?

Just click on the Voicemail Tab on the left hand side. Add a new voicemail mailbox and take note of its number.

Now click on the extensions tab and select the mailbox. This will give your phone a Message Waiting Indicator or stutter dialtone when you have new messages. Now you must turn on Divert for Busy/30s (30s = 30 seconds, you can pick a different value if you wish). Then choose "Mailbox: x" for Divert to.

Now if your phone is busy, or it is unanswered for 30s, the caller will be sent to your voicemail box!

How do I setup Asterisk (SIP Trunking Customers)?

Asterisk is fully compatible with Maxo Telecommunications VoIP. You can click here to view the setup guide.

Remember to tick the checkbox with an * (asterisk) above it for any extensions that you register to with an Asterisk PBX. This will cause our servers to pass DID information onto your asterisk PBX.

Note: If you tick the checkbox with an *, and then use a regular phone to connect to that extension, you may be unable to receive calls.

Where are the setup guides?

View them right here!

How quickly can I use my account? (Delivery of Service)

The account setup process is completely automatic, although every account is manually reviewed shortly after it is created. After you sign up you must make a payment to initialise your prepaid balance. From there, you can choose a plan. The pro-rata plan fee will be deducted from your initial balance. After you have added funds to your account, you are all set to make calls. On your first call, you will be automatically redirected to a verification program which will record you saying your name, address and landline number. This is for verification purposes and must be done - if you do not complete the verification procedure correctly, your account may be suspended. You cannot make a call until you have done this verification procedure.

The entire process takes less than 5 minutes, and the verification only happens once.
