How long does a business phone system installation take?

Most small business phone system installations (10–20 phones, single location) take a half-day to a full day on-site. Most of the configuration work — extension programming, auto-attendant setup, ring groups, voicemail — happens before installation day so the technician arrives with a pre-configured system. The on-site time covers physical phone deployment, system testing, number port cutover, and staff training.

Will my phones work during the transition to a new system?

Yes. Phonewire initiates number porting in the background before installation day. Your existing phone system continues handling all calls normally during the porting window (typically 2–5 business days). On installation day, the new system is fully installed and tested before the number port cutover — the window between the old system going inactive and the new system being live is typically seconds.

Can I keep my existing phone numbers when switching systems?

Yes. All existing business phone numbers port to the new system. Phonewire handles the entire porting process — you don't need to contact your current carrier. Porting typically takes 2–5 business days and happens before installation day so your numbers are ready to activate on cutover.

Does Phonewire train staff on the new phone system?

Yes, staff training is included in every Phonewire installation. Before the technician leaves, staff receives hands-on training on the phones — how to transfer calls, set up voicemail, use the Linkus UC mobile app, place calls on hold, and any features specific to their role. The people who use the system daily get shown what matters for their work, not a general feature overview.

What is included in Phonewire's professional installation service?

Phonewire's professional installation includes: pre-installation system configuration (extensions, auto-attendant, ring groups, voicemail), number porting, on-site hardware deployment, complete system testing and verification, number port cutover, staff training, and ongoing U.S.-based support after installation. There is no separate configuration or setup fee — the full scope is quoted upfront.

Business Phone System Installation

A business phone system is not a consumer product. It doesn’t come out of the box, get plugged in, and work. It requires configuration that’s specific to your business — your extensions, your call routing, your auto-attendant greeting, your voicemail setup, your ring groups, your after-hours handling. Done right, installation day is unremarkable: phones work when the technician leaves, your staff knows how to use them, and everything is exactly the way you asked for it. Here’s what that process actually involves.

Before Installation Day

Most of the real work in a Phonewire installation happens before anyone arrives at your office. Once you’ve approved a quote, Phonewire’s configuration team builds out your system remotely:

Extension programming. Every extension is created and assigned — employee names, direct numbers if applicable, voicemail boxes. BLF (Busy Lamp Field) keys on reception phones are programmed to show the right names and extensions. You don’t arrive on installation day to a blank system and start figuring out how to name a phone.

Auto-attendant configuration. Your greeting is recorded (either Phonewire records it from a script you provide, or your team submits a recording). Menu options are mapped — “Press 1 for Sales, Press 2 for Service” — and each option routes to the correct ring group or extension. After-hours messages are set up separately from business hours.

Ring groups and call routing. Who answers when the main number rings? In what order? After how many rings does it expand to the next person? What happens if nobody answers? All of this is configured before the phones are shipped, based on the information gathered during the quote process.

Number porting initiated. Your existing business phone numbers are submitted for porting to the new system. Porting typically takes 2–5 business days and happens in the background before installation day. During the porting window, your existing system continues to handle all calls normally — nothing changes for your staff or your callers until the scheduled cutover.

Hardware preparation. Every phone is pulled from inventory, updated to current firmware, and pre-configured with its extension credentials. Some phones arrive pre-labeled. The technician arrives with a system that’s already set up, not a box of parts to figure out on-site.

Why pre-configuration matters: A system configured from scratch on-site takes 4–8 hours on a good day. One that arrives pre-configured takes 1–2 hours to physically deploy and test. Pre-configuration also means errors are caught before installation day rather than discovered while your staff is waiting to make calls.

Installation Day

A Phonewire technician arrives at your location on the scheduled date. For a typical small business installation (10–20 phones), the on-site work takes a half-day to a full day depending on the building layout and how much wiring is already in place.

Hardware deployment. Each phone is connected to the network via Ethernet, verified for power (PoE from the network switch or AC adapter), and confirmed as registered to the system. Desk stands are attached, handset cords connected, and phones placed at workstations.

Final configuration verification. Every extension is called and answered. Every voicemail box is confirmed working. The auto-attendant is tested — calls are placed to the main number and each menu option is followed through to confirm correct routing. Ring groups are tested with the primary contact unavailable to verify fallback behavior. After-hours routing is tested.

Cutover. When all phones are confirmed working, the number port cutover is executed. Your old system’s lines are released, the ported numbers activate on the new system, and inbound calls begin routing through the new platform. The window between the old system going inactive and the new system being live is typically measured in seconds.

Staff training. Before the technician leaves, staff receives hands-on training on the phones: how to transfer a call, how to set up or retrieve voicemail, how to use the Linkus UC mobile app, how to place a call on hold and pick it up from another phone, and any other features the business specifically needs. The people who use the system every day get shown the things that matter for their role — not a general overview of every feature on the phone.

After Installation

Phonewire’s U.S.-based support is available by phone during and after business hours. When something needs to change after installation — a new employee, an updated auto-attendant greeting, a different ring group configuration, a new extension — you call the same number you called to get the system installed. The person who answers knows your system. Changes are typically made same-day.

There’s no ticket queue and no first-line support that escalates to someone who actually knows your configuration. When you call Phonewire, you reach a person who can log into your system and make the change while you’re on the phone.

What About Remote / Install-Assist Installation?

For businesses where a technician visit isn’t necessary — typically smaller installations where the customer or their IT person is comfortable connecting Ethernet cables and has a working network — Phonewire also offers a remote-assisted installation. The system is pre-configured and shipped to you; on a scheduled date, you connect the hardware and Phonewire’s team logs in remotely to complete the final configuration and verify everything is working.

This option works well for technically comfortable customers with simple, single-location setups. For multi-location deployments, complex wiring situations, installations where staff training is important, or any business without internal IT resources, professional on-site installation is the right choice. When you discuss the project with Phonewire, we’ll tell you honestly which approach fits your situation.
