The 8-step VoIP implementation guide for small businesses

Many small and growing businesses are moving away from using personal phones for work. That’s because VoIP services offer a more professional image. They also make it easier to separate work and life and come with the features they need to grow. For example, texting, automations, and integrations with other software.

Luckily, VoIP implementation is pretty straightforward. Here’s how to install a VoIP system in eight steps, plus five best practices to ensure a smooth experience.

What is VoIP, and how does it work?

VoIP, or Voice over Internet Protocol, is the technology that lets you make calls and send texts over the internet. VoIP works by sending voice data packets through an internet connection. These packets get reassembled into audio on the other end so people can hear you.

Compared to traditional phone systems, VoIP is much simpler to manage. Analog PBX systems tie you to a physical line through the Public Switched Telephone Network, or PSTN. VoIP is more flexible. You can use VoIP on devices you already have, like your phone or computer. But if you need to, you can also use a physical desk phone.

Keep in mind not all VoIP service providers integrate directly with desk phones. For example,  Quo, formerly OpenPhone, doesn’t. However, the platform includes apps for PC, Mac, Android, and iOS devices.

3 things you need before going through with VoIP implementation

There are three things you need to implement VoIP:

1. A reliable internet connection 

VoIP traffic runs through the internet. That means you’ll need a stable connection for the best-sounding calls.

The FCC recommends internet speeds with:

• Less than 0.5 Mbps download speed. That’s about the same as streaming music. This is up to 40 times less than streaming Standard Definition video.
• 100 Kbps of bandwidth per concurrent call. That means if you want to take up to five calls at a time, you’ll need a minimum of 500 Kbps of bandwidth. For context, 500 Kbps is about how much it takes to stream a song. 

You can use wireless options like WiFi, cellular data, or hotspots. If you have a desk phone, you can plug it directly into your router using an Ethernet cable. This gives you the most stable connection.

🤔 Why go wired? With VoIP, you don’t have to use a wired connection. But it can be more reliable than WiFi or hotspots. If you have a team member who makes a lot of calls per day and spends most of their time at a desk, you can opt for a wired connection.

2. A high-quality VoIP provider

The VoIP provider you choose impacts everything, from the features you get to the call quality and the reliability of your phone.

So, to choose the best VoIP app for you and your customers, look for:

• Solid uptime: High uptime means everything works as it should. Your customers can reach you, and you can reach them.
• Scalability: You should be able to add new users, numbers, and features in just a few clicks.
• Public pricing: Browse review sites and user forums like Reddit to check for hidden fees or add-on costs.
• Standard business tools: You shouldn’t have to pay extra for fundamental features like texting, call routing, or voicemail transcriptions.

3. Devices to make calls

All you need to use VoIP is an internet-enabled device, like your phone, tablet, or computer. You don’t have to purchase any new equipment. Platforms like Quo run on both iOS and Windows/Android. Your team can use any device they prefer; they can download the app and get started within minutes.

This is the primary way most businesses use VoIP platforms. Though some businesses might opt for hardware as well. 

Optional: Hardware

You don’t need desk phones and VoIP headsets to implement VoIP. But they can give you a more traditional calling experience. Your support and sales teams can make and receive calls hands-free. Plus, they can make it easier to hear callers in noisy offices.

If you want a similar calling experience without the hardware, you can have your team download the app to their devices. Then, connect with Bluetooth headphones to block out noise like a traditional handset.

How to set up VoIP in 8 steps

VoIP installation can be fast and easy. You just need to follow a few simple steps:

1. Assess your communication needs 

It might seem tempting to Google “best VoIP for businesses,” and go straight to comparing providers. But you’ll save yourself time and effort in the long run if you start by clarifying your needs first. You can quickly eliminate providers that don’t fit. This beats testing dozens of options, only to find they’re missing key features.

Here are some questions you can ask yourself:

Team size and usage:

• How many people will use the phone system?
• How many people need to make simultaneous calls?
• Are you a remote business? Or an in-office team?

Business needs:

• Do you need to make international calls?
• Are there any non-negotiable features? Some examples include call transcripts, shared numbers, and texting.
• Do you need HIPAA compliance?
• Do you need to connect with existing tools like CRMs?
• Do you need to take calls 24/7? 

Current phone situation:

• What are your pain points with the existing phone system? 
• Do you make a lot of outbound calls?
• What necessary features does your current phone system lack?
• What are some nice-to-have features you’d like in the future?

2. Test your connection

Make sure your internet connection can handle VoIP calls before setting up a VoIP system.

First, use fast.com or Speedtest by Ookla to measure your bandwidth. One VoIP call only needs about 100 Kbps of bandwidth. 

Here’s the formula to figure out how much bandwidth you need:

Total bandwidth requirement = Number of concurrent calls X 100 Kbps

Let’s say you usually have 10 calls going on simultaneously. In that case:

10 [calls] X 100 Kbps [per call] = 1,000 Kbps, or 1 Mbps

Of course, 1Mbps is the minimum requirement. Other devices and activities compete for bandwidth. To be safe, you’ll want at least a 25% to 30% buffer. That’s at least 1.25–1.3 Mbps more.

But speed isn’t everything. You should also check the quality of your internet connection. This includes measuring VoIP jitter, latency, and packet loss. Here’s a quick breakdown of these metrics and ranges:

Criteria	Definition	Acceptable Range
VoIP jitter	Audio stuttering	Under 30 ms
Latency	Time delay	Under 150 ms
Packet Loss	Audio choppiness	Below 1%

If you’re a fast-growing business, don’t forget to factor growth to best assess your needs. Budget extra bandwidth to account for peak calling times and increasingly high call volumes as you scale.

Pro tip: Use Quality of Service to prioritize voice traffic

Quality of Service, or QoS, helps you focus on voice traffic. It does that by reducing bandwidth for other processes or devices while on a call.

Let’s say someone at the office is taking a professional development course on their computer. QoS makes sure your call still gets priority by limiting their bandwidth until your call is done.

You don’t need QoS to ensure quality VoIP calls, but it’s something to consider if you have limited internet.

3. Plan your phone number strategy

You’ll have two options for your number: keep your old one or get a new one.

If you want a new number, you can choose from a few options:

• Local numbers help you build a local presence.
• Toll-free numbers create a professional image. They also ensure customers don’t have to pay for calling you.
• Vanity numbers are more memorable for customers — think 1-800-FLOWERS.
• International numbers support global expansions.

Quo offers local US, Canadian, or North American toll-free numbers for every new user on your account. We also offer competitive international rates.

If you’re porting your number, make sure the provider you pick supports that — and does so for free. For example, with Quo, you can easily port in your number for free. You can start the process by filling out our two-minute form in-app. A provider like Google Voice, on the other hand, charges you $20 to port in your number.

Porting typically takes around 5–12 business days. But don’t worry. Your number should be accessible with your current provider until the porting process is complete.

4. Choose your VoIP provider

Your VoIP provider will impact customers, team members, and future prospects. Here’s a simple framework to help you choose the best provider:

• Test multiple providers during free trials: Try key features with your team during business hours. Test all the apps and the browser versions. In particular, test the mobile app on the go. 
• Schedule product demos when trials aren’t available: Ask to see specific features in action. Just be sure to watch for evasive answers about limitations.
• Check review sites and forums: Browse G2 and Reddit for real user experiences. This will help you get a fuller picture beyond marketing claims.
• Evaluate implementation support: How clear and well-updated is the company’s documentation and tutorials? Is customer support responsive? Does the platform give you guided onboarding, or is it automated self-service?
• Verify compliance requirements for your industry:  Ensure the provider meets your industry requirements. For example, you might need HIPAA compliance if you’re in healthcare or SOC 2 compliance if you’re in finance.

When evaluating providers, compare them in these five categories:

Features

Look for VoIP features that help you stay responsive, provide customer service quickly, and close more deals.

This includes:

• Shared numbers: Split responsibility for incoming calls. Multiple team members can manage calls, texts, and voicemails from the same number.
• SMS and MMS support: Send and receive text and rich media like images from your business number.
• Texting automations: Give the impression of being responsive, even when you’re gone or busy. Quo offers auto-replies and scheduled messages so you can keep in contact around the clock.
• Call handling features: Send calls to multiple team members at once or in sequence with ring groups. Or direct callers to the right person or department with IVR phone menus.
• Call recordings and summaries: Keep records of conversations for quality control, training, or dispute resolution. With Quo, you can record calls on demand or automatically.
• AI voice agents: Never miss opportunities when you’re away from the phone. Sona takes calls 24/7, answers common questions, and captures key details so you can follow up later.
• Call analytics: This lets you track key details about your business so you know how to optimize in the future. For example, you might notice high call volumes on specific dates or times. This way, you can adjust staffing or improve call handling.
• Integrations with business tools: Connect with platforms like Slack, HubSpot, Make, or Zapier to save time and keep information organized. On Quo, you can also use our API for more custom integrations as your business grows. 

Scalability

A scalable phone system adapts to your business as it grows and your needs change. For example, it will let you:

• Add or remove users quickly: Scale your team up or down without buying new hardware or waiting for technician visits. Quo lets you add new users just by entering their email addresses.
• Flexible numbers: You can buy, share, or transfer VoIP numbers between team members as needed.
• Multi-location support: Rather than creating new accounts for each business department, you can manage all your locations and team needs on one account.
• API availability: These allow you to set up custom integrations. For example, you could create CRM automations like call logging or contact syncing.
• Easy upgrades: Add new features to your plan whenever the need arises.
• Ongoing improvements: The best providers consistently improve existing features and add new ones. They may also have a public roadmap of specific features and requests.

Long-term value

Pricing pages give you a general idea of costs. But long-term costs may take more digging to find, like add-ons and fees.

Avoid surprises by choosing a provider that offers:

• Per-user pricing. You shouldn’t have to pay for users you don’t need.
• No minimum user requirements. Some providers lock advanced features behind higher-tier plans with minimum seat requirements. This might force you to pay for more than you need.
• No long-term contracts. That way, you can downgrade or switch providers whenever you need to.
• Zero hidden fees or limits. The best phone systems don’t have caps on calling or texting. Plus, there shouldn’t be early termination fees, activation or setup fees, declined payment fees, or porting fees.
• Necessary features on the base plan. Fundamental features like unlimited calling and texting shouldn’t be considered add-ons. If you’re going to pay for a phone system, you should at least get what comes standard on personal cell plans.

Security

More than one in two small business owners will deal with security issues like fraud. That’s because many bad actors see small businesses as vulnerable prey.

A secure small business phone system can protect your calls, messages, and customer data from unauthorized access.

A secure VoIP provider has these features:

• End-to-end encryption: Encryption scrambles your messages when they’re stored or in transit. That means no one but you and the recipient can read them.
• Two-factor authentication, or 2FA: Get peace of mind with an extra layer of security whenever you sign in.
• User permissions: Decide who on your team should be able to manage billing, change settings, or read sensitive info.
• Automatic updates: The software should automatically roll out new security patches so it’s always its best and most secure version.
• SOC 2 compliance: This is especially important for legal or financial service providers that need third-party safety verification.
• Compliance certifications relevant to your industry. This might be HIPAA, SOX, or NIST CSF.

Reliability

Your customers need to reach you all the time, sometimes even when you’re sleeping.

So, you need a reliable VoIP provider that gives you:

• High uptime: The higher the uptime, the fewer customers you’ll miss.
• Redundancy: Backup systems and servers let you keep making calls and sending texts even if one system goes offline.
• Disaster recovery: How do they handle security monitoring? What’s their incident reporting strategy?
• Real-time status updates: You should be able to easily check for outages on a public status page. Quo, for example, has this real-time status page:

5. Set up your VoIP system

Now that you’ve picked the perfect provider, it’s time to set up the software itself.

Plan your organizational structure 

Before setting up any user accounts, think through how you want to organize your team.

A few things to keep in mind while planning:

• Department or team groupings: How should you group your users? Consider grouping by department, function, or location.
• User roles and permissions: Who should have admin access versus regular user access? For example, on Quo, admins will have access to details like billing and customer call recordings. Regular users can access the same calls, texts, and voicemails on shared numbers, but they can’t modify workspace settings like admins or owners.
• Number sharing: Which numbers will be shared across multiple team members? And which ones should be kept separate? You can always assign or unassign numbers within a few clicks in Quo.

Set up Quo

You can set up Quo in four easy steps:

1. Sign up for a Quo account. Similar to Netflix and Spotify, you’ll pay a monthly fee per user.
2. Download the softphone app on your phone or computer, or log in from the web.
3. Choose a business phone number. Pick between local, toll-free, or vanity numbers. If you want to port in a number, you’ll be given a temporary one until the port request is complete.
4. If you plan to text US numbers, complete US carrier registration. Quo can help you do this in-app so you can send unlimited texts to US and Canadian numbers.

If you want to port your number, you can do so in the app after your account is set up.

Optional: Set up hardware

If you choose to add hardware, now’s the best time to connect it.

You’ve got a few options:

• Desk phones, which work well if you’re not ready to give up traditional office equipment. These run around $40 to $350 per unit.
• Headsets for improving audio. Prices range from $17 to $300 for a high-end model.
• Analog telephone adapters, or ATAs, squeeze the last bit of life out of existing desk phones. 

6. Configure your VoIP phone settings

The next step is to adjust your business phone settings so they match what your team and callers need.

This includes:

Foundational settings 

Start by adjusting your most essential features. 

These include:

• Business hours: Ensures calls are handled differently during working hours versus outside them.
• Voicemail greeting: Create the right first impression whenever you can’t answer the phone. Quo gives you three options: record your own audio, upload a file, or use our AI business voicemail generator.
• Auto-replies: Let customers know you’ve received their messages and offer next steps while they wait for a reply. You can use Quo to set up different messages, both during and after business hours.
• Call forwarding rules: Make sure callers get to the right place automatically. With Quo, you have two options: forward all calls when your business is closed for a holiday, or set up conditional forwarding. This could be useful for redirecting callers after hours. 
• Integrations: Automate tasks for your team so they can spend more time focusing on making customers happy. Through Make, Zapier offers integrations with 8,000+ tools. You can also integrate natively with platforms like Slack and HubSpot. 
• Mobile apps: Download your provider’s app so you and your team can make and take calls from anywhere. This is crucial for remote and field workers.
• Backup plans: Create a plan for when the internet goes down to give yourself peace of mind. With Quo, it’s as easy as setting up call forwarding to an external mobile or landline number.

Finally, invite team members by entering their emails. Then, assign a role and a phone number. Everyone on your team will get their own phone number. You can also add them to a shared phone number to split responsibility for incoming calls and texts.

Advanced call routing features

Advanced routing features let customers reach the right person with minimal intervention from your side.

Quo offers an intuitive call flow builder that lets you configure each step visually. Here are some call routing features to set up for the best call handling:

• Ring groups: Ring multiple team members at the same time, in a set sequence, or in random batches.
• Auto-attendant or phone menu: Create an automated phone menu callers can use to direct themselves. An example is the classic “Press one for sales, or press two for support.” 
• Do not disturb, or DND, call forwarding: Use this feature when you don’t want to receive phone notifications. This forwarding rule ensures incoming calls are still handled appropriately. This might be sending the call to another team member, your voicemail, or Sona.
• AI voice agent: Quo’s Sona can capture overflow calls, answer questions, or record callback details.

7. Make test calls and check your system

To be sure your installation went off without a hitch, test your system to identify any bugs or issues. Here’s how:

• Call your business number from another number. Check for echoing, choppy audio, and/or dropped calls.
• Test each of your features. Is your phone menu working? Are auto-replies going out as expected? If not, check the provider’s resource center for help. If the issue persists, contact support.
• Check the mobile and desktop apps. Check especially for issues with notifications, ringing, or softphone performance.

8. Train your team on VoIP features and add-ons

The final step is onboarding your team so they can get familiar with your new phone system.

First, start training them on:

• Transferring calls
• Putting customers on hold 
• Checking and managing voicemails 
• Using “Do Not Disturb” mode
• Making calls from all devices 
• Navigating contacts and call history

Then teach them to use any advanced features on your plan. This includes call forwarding, recording, and third-party integrations.

You can train your team in several ways, depending on your setup. If you’re in an in-person office, a half-day onboarding session could work. If you’re a hybrid team, you can make short videos recording your screen and walking team members through specific features.

5 best practices for a smooth VoIP implementation experience

For the best implementation experience, be sure to:

1. Plan your number port early. Number porting takes 5–12+ business days. Plan accordingly to avoid problems like denied paperwork.
2. Set up a backup for taking calls. Forward calls to a mobile number or secondary number in case the internet goes down. Just make sure to test your backup number to ensure it works.
3. Have an after-hours plan. Create systems to help answer questions and capture leads outside of business hours. You can set up a custom voicemail, create auto-replies, or enable an AI voice agent like Sona.
4. Monitor missed calls regularly. Track missed call volume. Look for patterns like specific times of day or team members, so you can address the root cause. For example, if certain team members get too many calls, redistribute them with call routing.
5. Review team permissions quarterly. People change roles all the time. Make sure you adjust team members’ access to specific phone numbers, recording features, and admin tools.
