Frequently Asked Questions

So you know you’d like to update your business phone system, but you’re stuck on the particulars like “how many SIP trunks do I need?” and “how much bandwidth do I need?” 

Here, we hope to address these issues for you to make your transition as seamless as possible.

Should you still have questions, please feel free to contact us and we will go over any extra information you may require.


How do I use a SIP Trunk?

When you order a SIP Trunk from Aatrox Communications you receive a URL, number, and authentication information.

On your PABX or device you enter these details, which allows the SIP trunk to be “registered” to you.

That’s it!

Calls made to the numbers assigned to your SIP Trunk will be routed over your SIP Trunk, and you can choose where and how they are treated from there (for example ringing a single handset, going to voicemail, or using something like a call queue, hunt group, or IVR).

Note: To get the most out of your PABX and SIP trunks you may choose to configure plenty of different options for routing, codec usage, number masking, and so on.

We’re more than happy to have a chat with you about your specific requirements.

Are Aatrox Communications SIP Trunks expensive to implement?

Every deployment is different, but with Aatrox Communications SIP Trunks we’ve helped many companies reduce their phone bills by up to 60%.

Our SIP Trunks should reduce both the fixed infrastructure portion of your bill, and the call cost portion.

How do Aatrox Communications SIP Trunks compare to others?

We believe that our SIP Trunks represent the best value available in Australia.

We have worked hard and invested in our infrastructure to ensure that our call quality is excellent and extremely reliable, and in our team to make sure that there is always a highly skilled engineer available to answer your call.

All of our infrastructure is in Tier 1 data centres within Australia to provide the lowest possible latency (learn more about our infrastructure) and all of our team is located in Melbourne and Sydney.

We’re consistently told that the support we provide is second to none.

How much expertise do I need to get started with VoIP?

You need to be comfortable setting up and managing your PABX.

Aatrox Communications can provide assistance with SIP Trunk registration and compatibility – but ultimately you are responsible for running and configuring your PABX.

If this is not something you’re comfortable with, give us a call – we work with some great Hosted PABX providers that we’re more than happy to put you in touch with.


What infrastructure does Aatrox Communications use to deliver SIP Trunks?

Our SIP Trunking infastructure is hosted out of Sydney and Melbourne Data Centres. There is an automatic failover between the two incase of an outage. Please contact sales for more information.

What happens if my PABX goes offline?

Aatrox Communications SIP Trunks can be configured to automatically failover if registration to your PABX fails.

This failover can include voicemail to email, a mobile number as an endpoint and so on.

Contact us to discuss high-availability and redundancy strategies.

How does Fax work over a SIP Trunk?

Depending on the configuration and functionality of your PABX, faxes may be able to be delivered to it directly over your SIP trunk.

If this functionality is not available, fax to email can be configured on Aatrox Communications’ SIP infrastructure.

How long does it take to provision a SIP Trunk?

Our Pay As You Go SIP Trunks are provisioned in a few minutes once payment details are verified.

Our Unlimited SIP Trunks take a little longer – but still usually under 24 hours.


Does it cost anything to get started?

Some – but not all – of our SIP Trunks have a setup cost. 

Your SIP Trunks are billed monthly in advance (so you would be charged for your SIP Trunk for July on the last day of June).

What payment methods are accepted?

We require payment by credit card unless specifically arranged.

We accept VISA, MasterCard and American Express cards.

What do I do if I am facing financial hardship?

Aatrox Communications will do everything we can to assist you through your financial hardship. Please see our financial hardship policy below:

How do I track my voice usage throughout the month?

You are able to track your unbilled voice usage for each number hosted in your account from the portal.

Once logged in with the details which are on the email you have received with your invoice:

1) Click Transactions

2) Enter the SAID (Number hosted with Aatr0x)

3) Run the report which will give you an excel export of all unbilled calls for the month
