How to Set Up a Virtual Phone System (Step-by-Step Guide)

TL;DR – Summarise this page with AI

If you are starting a business or moving away from a traditional phone line, setting up a virtual phone system is one of the most practical things you can do early on. It costs a fraction of what old-style hardware systems used to run, it takes less than a day to get up and running, and your team can use it from anywhere.

This guide walks you through the full setup process using Nuacom – from picking the right plan to making your first test call. No IT background needed.

What Is a Virtual Phone System?

A virtual phone system routes calls over the internet rather than through copper telephone lines or on-site PBX hardware. Instead of buying equipment and paying an engineer to configure it, you sign up for a cloud-based service, add your users, and you are live.

With Nuacom, your team gets a full business phone system – auto-attendant, call routing, call recording, voicemail to email, mobile and desktop apps, and a lot more – all managed from a simple online dashboard. There is nothing to physically install.

What You Need Before You Start

The setup process is straightforward, but having a few things ready in advance will make it faster:

• A reliable internet connection – broadband or 4G/5G both work. Nuacom recommends at least 100 kbps per active call.
• A list of your team members – names, roles, and email addresses for each user you want to add.
• An idea of how you want calls handled – for example, do you want callers to hear a menu (“press 1 for sales, press 2 for support”) or go straight to a person or team?
• Your business greeting recorded or written out – even a rough draft is fine. You can update it any time.

That is genuinely all you need. No hardware purchases, no wiring, no waiting for an engineer.

Step-by-Step: How to Set Up Your Virtual Phone System with Nuacom

Step 1: Choose a Plan and Sign Up

Nuacom has two main plans. The Unlimited plan starts at €19 per user per month on annual billing (€25 per user per month on a rolling monthly basis). It covers most of what a growing business needs – unlimited calls to 30+ countries, 2-way business SMS, SMS campaigns, desktop and mobile apps, virtual queues, call analytics, automated call recording, auto-attendant, voicemail to email, HubSpot integration, and 40+ features.

The Enterprise plan starts at €25 per user per month on annual billing (€35 per user per month monthly) and adds advanced call reporting, live wallboard, call coaching, queue management, auto dialer, video calling, and a wider range of CRM and helpdesk integrations including Salesforce, Zoho, Pipedrive, Zendesk, and more.

Not sure which fits your team? Check the full breakdown on the Nuacom pricing page. You can also start a free trial to test the platform before committing.

Once you have signed up, you will receive login credentials for the Nuacom admin portal. That is where everything gets configured.

Step 2: Get Your Business Phone Number

When you sign up, Nuacom includes a free local number. You can choose the area code that best represents your business – New York, Dublin, London, or wherever your customers are based.

If you need additional numbers, they are available as an add-on. Many businesses add a second number for a different department or location. All of them are managed from the same dashboard.

If you already have a number you want to keep, Nuacom supports number porting. You stay reachable on the same number your customers already know – nothing changes on their end.

Step 3: Add Your Users

Inside the admin portal, go to the Users section and add each team member. For each user, you will set:

• Name and extension number
• Email address (used for voicemail to email notifications and login)
• Their role and permissions
• Which devices they will use – desktop app, mobile app, or a physical VoIP desk phone

Once added, each user gets an invite to download the Nuacom app and set their password. The setup on their side takes about two minutes.

Step 4: Set Up Your Auto-Attendant

The auto-attendant is the automated greeting callers hear when they ring your number. It is one of the first things that shapes how professional your business sounds, so it is worth doing properly.

In Nuacom, you can upload a pre-recorded audio file or use the text-to-speech tool if you need something quick. A typical greeting sounds like:

“Thank you for calling [Your Business Name]. For sales, press 1. For support, press 2. To speak with our team directly, press 0 or stay on the line.”

You can also set up time-based greetings – one message during business hours and a different one outside them – so callers always hear something relevant. This is handled through time-based call routing, which runs automatically once configured.

Step 5: Configure Your Call Routing

Call routing decides where a call goes after the greeting. With Nuacom you can route calls to:

• A specific user or extension
• A team or call group (rings multiple people at once or in sequence)
• A voicemail box
• A different number, such as a mobile, using call forward to mobile

For most small businesses, a simple setup works fine – one menu option routes to sales, another to support, and anything outside office hours goes to voicemail or a mobile. You can always expand this as the team grows.

Nuacom also includes call backup, which automatically reroutes calls if your internet drops. Worth switching on early so you never miss a call due to a connection issue.

Step 6: Download the Desktop and Mobile Apps

Nuacom has both a desktop softphone app (Mac and Windows) and a mobile app (iOS and Android). Your team can make and receive business calls from their laptop or phone, with the full set of call features they would expect on a desk phone.

Once users have been added in step 3, they log in with their credentials and the app is ready to use. No configuration needed on their end.

The mobile app is particularly useful for remote staff or anyone who moves between locations. Calls come through on their business number – customers never see a personal mobile number.

Step 7: Turn On Voicemail to Email

Voicemail to email sends a recording of every voicemail straight to the user’s inbox. It is a small thing that makes a big difference – no more logging into a phone system to check messages.

You can enable this per user or for shared group voicemail boxes. Set the destination email in the portal and it runs automatically from that point on.

Step 8: Test Before You Go Live

Before pointing your main number at the new system, run through a few test calls internally:

• Call the main number and check the greeting plays correctly
• Test each menu option and confirm calls route to the right place
• Leave a voicemail and check it arrives by email
• Make an outbound call from the desktop and mobile app
• Check that calls outside business hours follow the after-hours routing

This takes about ten minutes and catches anything that needs a quick tweak before real customers call in.

Features Worth Switching On From Day One

Once the basics are running, these Nuacom features are worth configuring early. They all come included in the plan.

• Call recording – every call is recorded automatically. Useful for training, compliance, and resolving disputes.
• Call analytics – see call volumes, peak times, missed call rates, and team performance from a single dashboard.
• Missed call email notification – alerts you by email any time a call goes unanswered, so nothing slips through.
• Missed call text back – automatically sends an SMS to a caller when their call goes unanswered, so you never lose a lead because you were busy.
• Instant callback widget – add a widget to your website that lets visitors request a callback. Rings your team immediately when someone submits it.
• Business text messaging – send and receive SMS from your business number, straight from the Nuacom portal or app. Two-way messaging and SMS campaigns are both included in the Unlimited plan.
• CRM integration – if you use HubSpot, Salesforce, Zoho, Pipedrive, or one of the other 50+ integrations, connect it during setup. Calls and notes sync automatically to the contact record.
