When you sign up to an OfficeHQ virtual reception service, you’ll be allocated a unique phone number. To ensure our receptionists can answer your calls, you need to enable call forwarding to your allocated number.

Who manages your call forwarding
Setting up call forwarding from your existing business number must be handled by you. We are unable to manage this on your behalf.
The method for setting up call forwarding also differs depending on a couple of things:
- Who your telecommunications provider is
- When you need OfficeHQ to answer your calls
- Immediately (the most preferred option)
- Only if they are not answered within a certain timeframe
- Only if there’s a busy signal
On this page we’ve included call forwarding instructions for popular telcos, however recommend that you double-check the settings with your provider in case they’ve changed their processes.
Types of call forwarding

Immediate call forwarding
When someone calls your business phone number, the call is forwarded straight away to your virtual receptionists.
Having calls forwarded immediately is typically the best solution for most businesses.
After-hours answering only
If you want to continue answering calls in-house during the day, but have after-hours calls answered by OfficeHQ’s virtual receptionists, you can simply:
- Turn on call forwarding at the start of every business day
- Turn off call forwarding at the end of every business day

Delayed call forwarding
When a call comes in on your business number, you or your team will have the opportunity to answer before it’s forwarded to your virtual receptionists.
This is used by businesses wanting a call overflow solution. That is, only having virtual receptionists answer if their in-house team members are too busy to answer, can’t get to the phone for any other reason or are already on another call.
“No answer” forwarding
Call forwarding will occur only if the call is not answered within a certain timeframe. Typically this would be between 5 seconds and 30 seconds, depending on your telecommunications provider and your settings.
“Busy signal” forwarding
Call forwarding will occur only if your line is already busy.

VoIP & Cloud call forwarding
VoIP and Cloud Phone Forwarding
If your business uses a VoIP or cloud-based phone system rather than a traditional Telstra, Optus, or Vodafone line, forwarding works a little differently. Instead of dialling a code from a handset, you’ll usually set it up through your provider’s online portal or admin dashboard.
How it generally works
Before you set it up
- Every VoIP and cloud phone system is different, so the steps and wording may vary.
- If your system is managed by an IT provider or reseller, they may need to set up the forwarding for you.
- Some systems apply forwarding to each user or extension, so make sure you are updating the right line.
- If you cannot find the setting, contact your provider’s support team. Call forwarding is a common request.
Further support
If your provider isn’t listed above, use the general instructions, check your provider’s support portal, or contact your provider’s support team. Still stuck? Contact OfficeHQ support and we’ll help you get set up.
