What is a business phone system for hybrid work?

How does one extension work on both an office phone and a home phone?

One extension can be registered to more than one supported device, allowing the same user to answer from an office desk phone, a home desk phone or a softphone. The exact number of simultaneous devices depends on the phone system and its configuration.

For example, an employee might have:

Some providers describe this as multiple devices on one extension. Vonage’s Australian documentation explains how a single extension can connect multiple phones, including an office desk phone, a home desk phone and a softphone.

The practical choice is whether both locations should ring at once or whether the system should select the correct device based on the employee’s schedule. Simultaneous ringing can be useful for flexibility, while schedule-based routing is usually easier for a small team because the user does not need to remember to change settings each day.

A system should also support a clear failover rule. If the employee does not answer at home, the call might move to their voicemail, a receptionist, a shared queue or another nominated extension.

Should hybrid staff use a softphone and desk phone?

A softphone and desk phone combination is useful when an employee wants the familiarity of a physical handset in one location but needs the flexibility of an app in another. The right choice depends on how often the person works from home, how much time they spend on calls and whether their home workspace is permanent.

A desk phone can make answering, transferring, parking and placing calls more deliberate, particularly for reception or administration roles. A softphone is more portable and can be used from a laptop with a headset, which may suit staff who move between locations.

The business should check whether the provider supports the same extension features on both devices. Some systems allow the softphone to transfer calls, monitor colleagues and show presence in the same way as a desk handset; others offer a simpler app with fewer controls.

For a broader comparison of handset types and setup options, see the small business phone system guide.

How does schedule-based call routing work for hybrid employees?

Schedule-based call routing sends calls to different devices or destinations according to a timetable, such as office hours, home-working hours, lunch breaks or after-hours coverage. It reduces the need for employees to manually switch their extension between locations.

A typical schedule might look like this:

The routing can be based on business hours, user schedules, ring groups or administrator-set rules. Optus describes business phone features that include routing calls to desk phones, mobiles or PCs, along with work schedules and call history.

For a small team, the schedule should be easy to understand and change. If an employee works from home on different days each week, the administrator may need a simple control for changing the active location, or the employee may need to select the correct device in the app.

Avoid building a routing plan with too many exceptions. A short set of rules—office, home, unavailable and after-hours—is easier to test than a complicated timetable that depends on individual calendar appointments.

Can presence show whether someone is available at home or in the office?

Presence shows whether a person is available, busy, away, in a call or otherwise unavailable. It can help colleagues decide whether to transfer a caller, send an internal call or allow the system to present a queued call.

Presence is not the same as physical location. A user may show as available while working from home, or show as busy while sitting at an office desk. It should therefore be treated as an indication of call availability rather than proof that someone is ready to answer immediately.

Microsoft Learn explains that presence can be influenced by user activity, the Teams application state and the Outlook calendar. That makes presence useful for hybrid work, but it also means calendar and status settings need to be configured carefully.

For example, a staff member attending an online meeting at home may appear busy even though they are physically at their desk. A call queue configured to use presence may then avoid presenting the call to that user.

Ask the provider:

Presence is most helpful when combined with a clear routing policy. It should support the schedule, not replace it.

What should a small business check before installing a hybrid phone system?

A small business should check the devices, network, call rules and administration process before choosing a system. The most important question is whether the same extension behaves consistently in both locations.

Use this checklist when comparing providers:

A home desk phone normally connects through the employee’s home internet connection. A softphone depends on the laptop’s network, headset, operating system and application settings. The provider should explain what happens when the home internet drops or the employee changes location unexpectedly.

The business should also test audio quality from the actual home workspace. Wi-Fi congestion, a poor headset, background noise and other applications using the connection can affect the experience even when the phone system itself is functioning normally.

For employees who spend much of the day on calls, use the guide to choosing a business phone headset for high-call-volume roles.

If the business has given up its premises entirely rather than mixing office and home days, the equivalent setup is a virtual office phone system.

Is a home desk phone better than a softphone for hybrid work?

A home desk phone is usually better for a permanent home workspace and frequent calling, while a softphone is better when the employee needs to move between locations or avoid extra hardware. Neither option is automatically better for every hybrid worker.

A desk phone can be useful when the employee needs physical buttons for transfer, hold or line appearance. A softphone may be more practical when the home workstation changes or when the employee already uses a laptop and headset.

The decision should be based on the employee’s actual work pattern rather than a blanket rule for every handset. A three-person office may need two permanent office phones, one home desk phone and several softphone licences rather than one identical device for every user.

How should an office manager set up one extension for two locations?

Start by mapping the employee’s weekly pattern, then assign devices and routing rules to match it. Do not begin with a list of features; begin with the question: “Where should this person’s extension ring at each point in the working day?”

A practical setup process is:

The test should include a caller reaching the employee at the office, the same caller reaching the employee at home, an unanswered call, an internal transfer and an outbound callback. Check that the caller sees the intended business number where the service supports business caller ID.

If a change involves forwarding calls to a mobile number, keep that as a separate design decision. The guide on forwarding a business phone to a mobile without losing caller ID covers that specific scenario.

What happens when a hybrid employee changes location during the day?

The system should either follow a published schedule or let the employee change the active device with a simple control. The important point is that changing location should not require customers or colleagues to learn a new number.

There are three common approaches:

A fixed schedule is usually the easiest for an office manager to support. User selection is more flexible, but the employee must remember to change it before starting work.

If a user frequently moves between locations during the same day, a softphone may be the most practical primary device, with desk phones used when the employee settles into a permanent workspace.

For rules that depend on whether a call is busy, unanswered or outside a defined period, see how conditional call forwarding works.

Does a hybrid phone system need special emergency-call planning in Australia?

Yes. A business should understand how its VoIP service handles emergency calls when an employee may use the extension from two locations. VoIP emergency-call arrangements can differ from traditional fixed services.

The Australian Communications and Media Authority explains that certain VoIP services can call Triple Zero, but callers using VoIP may need to provide their current town and state. ACMA also notes that stored service-address information should be kept accurate because it may be used in an emergency.

Before deployment, ask the provider:

This is a service and safety configuration issue, not simply a handset choice. Document the answer for staff who may work from home.

How many handsets does a hybrid small business actually need?

The number of handsets should reflect simultaneous users and fixed workstations, not the total number of employees. A business may need fewer physical phones than staff if some employees use softphones or share desks.

For example, a five-person business might have three office desk phones, one home desk phone and five softphone licences. A receptionist or accounts role may need a dedicated handset, while a manager who works from home two days a week may use a softphone.

When requesting a quote, provide:

A quote based only on “three to 20 handsets” can miss the real requirement. The correct design may involve a mix of handsets, softphone users, extensions, call queues and routing rules.

FAQ: What is the simplest hybrid work phone setup?

The simplest setup is one extension with an office desk phone and a softphone for home use, supported by a fixed working-hours schedule. Unanswered calls then move to voicemail or a nominated team destination.

Can one business extension ring on two phones?

Yes, many cloud phone systems can associate one extension with multiple devices, although the supported device count and simultaneous-ringing rules vary by provider. Confirm this before ordering hardware.

Is presence required for hybrid work?

No, but presence can help colleagues and call queues identify whether a user is available, busy or in a call. It works best when paired with clear schedules and sensible status rules.

Do all hybrid workers need a home desk phone?

No. Employees who work from home occasionally may only need a softphone and suitable headset, while phone-heavy users with a permanent home workspace may prefer a dedicated desk phone.
