Most business phone systems were designed for an office where everyone sits at a desk. The main number rings a reception desk. Extensions route to workstations in a building. Voicemail waits in a box until someone checks it. That model breaks the moment employees start working from home, splitting time between locations, or simply spending most of their day away from their desk. Here’s how to configure a Phonewire system so your phones work correctly whether your team is in the office, at home, or both.

The Core Tool: The Linkus UC Mobile and Desktop App

Every Phonewire system — both the Hybrid on-premises system and the cloud-hosted option — includes the Linkus UC app at no additional per-user cost. Linkus runs on iPhone, Android, Mac, and Windows. When a remote or hybrid employee installs it, they get a full business extension on whatever device they’re using.

What “full business extension” means in practice:

The same extension number works everywhere. If your office extension is 105, you reach extension 105 whether you’re at your desk phone, your laptop at home, or your cell phone at a client site. Colleagues can call your extension and reach you wherever you are. Your desk phone and mobile app ring simultaneously — you answer whichever is closer.

Outbound calls display the business number. When you call a client from the Linkus app, they see your business number — not your personal cell. They call back on the business number. The business number and client relationship stay with the company, not with whichever device you happened to call from.

Transfers and call management work normally. You can transfer a call from the mobile app to a colleague’s extension, place a call on hold, access the company directory, and check voicemail — the same functions available on a desk phone, from any device with internet access.

Voicemail goes to email. Every voicemail left on your extension arrives in your inbox as an audio file within seconds. You don’t miss a message because you weren’t in the office to check the physical phone. With voicemail transcription enabled, it also arrives as readable text.

Setting Up Ring Groups for Hybrid Teams

The most common remote work phone problem isn’t technology — it’s routing. The main number rings the reception desk. The receptionist is working from home today. Nobody else’s phone is configured to catch the call. It goes to voicemail.

The fix is a ring group that accounts for how the team actually works, not how the office was originally wired. Phonewire configures ring groups during installation and adjusts them whenever your team structure changes:

Simultaneous ring: When the main number is called, every extension in the group rings at the same time — desk phones in the office and Linkus apps on remote employees’ devices. The first person to answer gets the call. Nobody misses it because someone happened to be away from their desk.

Sequential ring (hunt group): The call rings one extension first, then moves to the next if unanswered after a set number of rings, then the next. Useful for reception-heavy setups where you want a specific person to answer first but don’t want calls to die if they’re busy.

After-hours routing: Remote employees often keep different hours than the office. After-hours routing sends calls to voicemail, to an on-call extension, or to a specific team member based on a schedule — without requiring anyone to manually forward or unforward calls. The system switches automatically at the configured time.

The Personal Cell Problem — and Why the App Solves It

Many businesses that went remote simply started using personal cell phones for business calls. This created problems that are still showing up years later: clients have personal numbers saved from 2020 that they still call directly. Employees who left took client relationships with them because the personal number went with them. Work calls arrive at all hours with no separation from personal calls because they all ring the same device the same way.

The Linkus UC app solves this specifically. Business hours settings stop routing business calls to the mobile extension outside of configured hours — employees get a clean break from work calls without turning anything off manually. The business number is what clients save, not the personal cell. When an employee leaves, their Linkus extension is simply deactivated and reassigned; there’s nothing to take with them.

Microsoft 365 integration: Linkus UC integrates with Microsoft 365 — contacts sync automatically, presence status reflects your calendar availability (if you’re in a meeting, your extension shows as busy), and calls can be logged against contacts. For hybrid teams already working in Microsoft 365, this makes the phone system feel like part of the same unified environment rather than a separate tool.

When Remote Employees Need a Desk Phone vs. the App

The app is the right tool for most remote workers — no hardware to ship, no setup complexity, works on devices they already have. But some remote roles are better served by a physical desk phone:

High call volume remote workers. An employee who handles 40+ calls a day from a home office will find a dedicated Yealink or Snom desk phone less fatiguing than a headset connected to a laptop. The phone is always on, always registered, doesn’t compete with other applications for audio, and has physical buttons for hold, transfer, and mute that are faster than navigating a softphone interface under call pressure.

Home offices with unreliable Wi-Fi. A desk phone connected via Ethernet at a home office delivers more consistent call quality than a laptop on Wi-Fi. If remote workers frequently report audio issues on calls, a wired desk phone often resolves it without any other changes.

Employees who don’t want the app on their personal phone. Some employees reasonably don’t want a work app on their personal device. A dedicated desk phone at their home office keeps work and personal completely separate on separate hardware.

Phonewire ships and provisions desk phones to home offices as part of a system deployment — the phone arrives pre-configured for the employee’s extension. They plug it into Ethernet, it boots up registered, and it works.

Conference Calls and Video for Remote Teams

For internal meetings and client calls with remote participants, Phonewire’s system supports conference bridging — a dedicated conference bridge extension that multiple callers (internal and external) can dial into simultaneously. Conference calls are included in the system without per-call fees.

For video meetings, Phonewire’s system integrates with Microsoft Teams and other video platforms — Yealink T5-series desk phones have Teams-certified versions that display the Teams interface directly on the phone screen. For businesses that use Teams heavily, this eliminates the context switching between phone calls and video meetings.

For conference room audio, Phonewire installs Yealink CP-series conference speakerphones — the CP925 is a popular choice for small-to-medium conference rooms — configured as extensions on the same system as everyone’s desk phones and mobile apps. A remote participant can be called directly from the conference room phone, transferred to a colleague, or brought into a ring group the same way as any other extension.
