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.

Infrastructure

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.

Compatibility

Which PABXs are Aatrox Communications SIP Trunks compatible with?

We’ve invested heavily in ensuring our SIP Trunks are compatible with a range of PABXs.

Which phones can I use with Aatrox Communications SIP Trunks?

You can connect any SIP-compliant physical phone or softphone to an Aatrox Communications’ SIP trunk.

That said, it is far more common to use a PABX such as 3CX.

The telephone requirements are then set by the PABX.

Can I connect an analog PABX with Aatrox Communications' SIP Trunks?

Definitely – and it’s a great way to get some of the benefits of SIP without the expense of replacing your PABX and handsets.

By using a PSTN Gateway (also called a VoIP Gateway) you can connect a SIP Trunk to an analog PABX.

The PSTN Gateway is a physical piece of hardware that essentially converts the digital SIP voice signal into an analog one that is compatible with your existing PABX.

This can directly replace one or more IDSN2, ISDN10 or ISDN30 connections, and immediately provides significant cost savings.

Can I use Aatrox Communications SIP Trunks outside of Australia?

Yes, absolutely.

You can register and use Aatrox Communications’ SIP Trunks from anywhere in the world (some anti-hacking restrictions apply but can be lifted on your account by request).

We have customers in the US, the UK, Europe, New Zealand, India, South East Asia, and the Pacific Islands, all using Aatrox Communications’ SIP Trunks to make and receive calls as though they were in Australia.

This saves money, and gives them additional flexibility.

Will Aatrox Communications' SIP Trunks work with my softphone (e.g Xlite)?

Yes, any SIP compliant softphone can be registered as an endpoint. 

However as mentioned above, it is far more common to use a PABX such as 3CX. The telephone and softphone requirements are then set by the PABX.

Do Aatrox Communications SIP Trunks have the availability to dial 111?

Yes, emergency calls can be made just like on an analog phone line.

However, if your internet connection goes down and you have no redundancy, you will not be able to make any calls (including to 111).

What codecs do Aatrox Communications' SIP trunks support?

  • G.711A (also known as G.711alaw)
  • G.711U (also known as G.711ulaw)
  • G.729
  • G.722
  • G.723
  • G.726-16
  • G.726-32
  • iLBC

Codec selection is performed during call setup as per RFC3265. All calls are transcoded to G.711A for termination on the PSTN.

Payment

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:
