Hosted PBX

Hosted PBX is only available as an optional extra to our Business VoIP product.

Smaller business customers who want a solution with unlimited standard calls in Australia, rented handsets and extensive PBX features should consider our Business Phone product. Business Phone does not have the full flexibility of Hosted PBX with Business VoIP.


Hosted PBX means businesses only need VoIP compatible handsets to make phone calls, with all call routing occurring at OntheNet’s Data Centre, leveraging the redundancy and backup systems in place already.

This solution is particularly cost-effective and efficient for businesses that operate over multiple sites because all sites can share the one phone system. Features such as call forwarding/diversion, after hours and on hold messages can be shared presenting a highly professional and consistent business image.

A full feature list is provided below. If you have any questions please contact us.

HD VoiceOntheNet Hosted PBX services use HD Voice by default (codec G.722).
Interactive Voice Response Menu (IVR)*Automatically answers and directs calls to a specific extension, hunt group or queue.
Also known as Auto Attendant.
Queues*Have queues setup to handle incoming calls for your different departments. A queue will keep a caller on hold until your staff become available or until the defined time period expires, after which the caller is redirected as required. This feature also includes a wallboard for you to view queue activity on a daily basis.
VoicemailChoose from traditional voicemail (via the handset) or Voicemail to Email.
If Voicemail to Email is chosen any voicemail that is left by a caller will be sent as an audio file (.wav) to the nominated email address.
Music on HoldPlay music to your clients while they are on hold.
Messages on HoldPlay messages to your clients while they are on hold.
Caller ID PresentationDisplays the phone number of the person calling you.
Caller ID MaskingAll of your outgoing calls can display the same number (eg your office number) so that your clients can easily identify who is calling them. Also known as CLI Overstamping.
Caller ID BlockingHave your Caller ID set to private either per extension or system-wide.
Call ForwardForward all calls to another number/extension or choose to forward calls only when the dialled number is busy, unreachable or the call is not answered for any reason.
Call Park & PickupAbility to put a call on hold and retrieved by another agent/extension.
Call TransferAllows a call to be transferred to another number or extension with or without speaking to the person that is to receive the call.
Call HoldPlace a call on hold, for example while attending to another call.
BlacklistsA system-wide feature that blocks incoming calls from specified numbers.
Do Not DisturbSet an extension to unavailable so inbound calls are treated as if the extension is busy.
Extension DiallingUsers within your PBX can call another extension using the extension number only.
For your clients to call an extension directly without being transferred by reception a DID number (phone number) must be assigned to the extension.
Hunt GroupsCalls a group of extensions with different ring strategies available (eg all at once or sequential). Group pickup allows a call to be picked up by any extension within the hunt group. Also known as Ring Groups or Call Groups.
Three-way CallingAllows for a third party to be added to a current call.
Time of Day Routing & SchedulingDirects incoming calls differently depending on the time of day and/or day of the week.
Paging & IntercomPaging allows a user to send a one-way page to multiple extensions. Intercom allows a user to start a one-way intercom style chat with another extension, which can be enabled to be two way. When used, the receiving extension will automatically answer the call and route the audio to speakerphone.

Some features are handset dependent and may not work as described if you choose to use a handset other than those offered by OntheNet. If you have any questions in regards to these features please contact us.

Paul Demetre
Review added 8/8/17: I have now been an OntheNet customer for over 10 years and I can say without any hesitation they are what every ISP should strive to be. Their customer service is second to none and I have never felt so well looked after. Just recently we had NBN rollout in our area but due to a NBNco problem we had to wait months for our connection. The entire process was handled by OntheNet and their awesome provisioning team. Paul and the rest of the provisioning team really stepped up to make sure the process moved as quickly as possible. Being able to speak with a local team was the crucial difference as most ISPs would have had me speaking to a overseas call center. I am now the happy owner of blazing fast 100/40mbps internet which has been sensational.I can't recommend OntheNet enough, they know what customer service is and we as locals need to support companies like this. Well done team!read more
