Combining VoIP & CRM comes with the biggest benefits:

• Your user conversion will increase by 283%
• Operational cost of your platform will go down by 77%
• The time taken for 1 call can be reduced by 39%

Integrating VoIP calls into your CRM software helps your teams to access user data and make calls from one place. They need not juggle between apps. Rather, they can find a customer’s past interactions, their preferences along with other important call details in real-time. 

This is a big transformation, especially in customer support operations. 

Going ahead, this article will discuss – what is VoIP integration and its benefits in detail. You’ll also learn about the top VoIP CRM integration softwares in the market to help you get started.

CRM With VoIP Integration: What You Need to Know?

VoIP integration means linking your internet-based phone system with other (or external) business tools. In this scenario, the business tools refer to CRM (Customer Relationship Management) platforms.

So, how exactly is this done?

You can rewrite the source code of your platform to connect these two technologies. However, the complete code amendments, testing and launching would consume a few months and pretty-much a lot of resources.

Instead, you can use API – Application Programming Interface, which gets it all done within a coffee break!

In the next section, we will discuss how exactly this is done!

How Does VoIP CRM Integration Actually Work (With An API)?

The goal is to connect your CRM software to your VoIP system so they can exchange real-time data and make things easier for you. To achieve this, you’ll need an API, a reliable one like MirrorFly that can act as the interface between both the systems.

There are 2 scenarios here. 1.You use your own VoIP app, 2. You are just starting to build a VoIP app for your team, 3. You are already using a third-party VoIP platform.

Using an API to perform this integration will work for the first two scenarios. The third scenario is out of hand and depends on the app’s compatibility with third-party extensions or plugins.

This is a perfect scenario, as you have the freedom to customize both VoIP and CRM according to your workflow, right from the start. This can be done even more seamlessly with providers like MirrorFly that offer APIs to build your own VoIP systems along with CRM integrations.

Whichever VoIP platform you use, this is how you can achieve the integration:

Step 1: Selecting your CRM platform

Given the aforementioned scenarios, you already have a VoIP system (either active or in the building). This means, you’ll need to choose your CRM platform that can take care of all your customer data efficiently and connect with your calling system.

Step 2: Linking VoIP + CRM using an API

Once you are ready with your VoIP source code and have a selected CRM, use the API to connect them both using authentication keys. They set up the endpoints and adjust the configurations so both systems can communicate with each other.

Step 3: Allowing Data Sync

Once connected, the API passes call information to the CRM automatically. This can include:

• Time of call (Connect time and Disconnect time)
• Caller identity (mapped with CRM contacts)
• Call duration 
• Notes taken during the call
• Call recordings (if enabled)

Step 4: Setting Up Click-to-Call & Caller Details

After integration, you can place the option in your CRM to make calls from the platform directly rather than having to use a separate app. When receiving a call, the CRM displays available information about the caller pulled from past interactions and call records that are stored in your system.

Step 5: Trigger CRM Actions Based on Call Events

Besides click to call and caller details, the API can also be used to automate actions in the CRM. You can easily create rules to follow-up tasks for missed calls, log completed calls, or send messages after a call ends.

So, that’s how easy it is to set up the VoIP CRM integration and helpful to automate everything that requires so much manual work.

What Can You Do with a VoIP CRM Integration?

✔ Keep Everything in Sync Automatically

VoIP CRM integration keeps your phone system and customer software working together without you having to lift a finger.

Any time a call comes in or goes out, the details like who called, when, how long it lasted, and which contact it was are automatically saved in your CRM. This happens in the background, often in real time, so your customer records, notes, deals, and tags are always up to date.

✔ Call Straight from Your CRM

With click-to-call, you can make a phone call by just clicking a number inside your CRM. This avoids dialing mistakes and saves time since you don’t have to switch between apps or manually type in phone numbers.

✔ Review Calls Instantly

Once a call ends, you can easily find the recording and any notes right inside the CRM. You don’t need to search for files or log anything manually.

It’s all saved automatically, which helps agents wrap things up quickly and stay organized.

✔ See Caller Info the Moment They Call

When someone calls, a pop-up instantly shows who they are and their full history with your business like past orders, open support tickets, and previous interactions.

This real-time customer card lets agents jump right into the conversation with context, without digging for details.

✔ Track Call Center Performance

Your CRM can also show you useful reports about your call activity like how many calls are coming in, how long they last, how often calls are missed, and how quickly issues get resolved.

These insights help teams spot what’s working and where improvements are needed.

✔ Set Up Smart Automations

The system can take action based on what happens during a call. For example, if a call is missed, it can automatically create a follow-up task.

If the call goes well, it might send a survey or email. You can also use it to send automated text messages when certain conditions are met, making follow-ups faster and more consistent.

5 Benefits of Using a VoIP CRM Integration

1. Automatically Collect Customer Call Data

VoIP CRM integration helps you collect important customer info without doing it manually. Every time someone on your team makes or receives a call, the system logs details like how many times they called, whether the call was answered, and how long it lasted.

It also tracks SMS messages, adding them directly to the customer’s file in the CRM so your sales team doesn’t have to do anything extra.

2. Cut Down on Costs

Using a VoIP phone system that works with your CRM can save your business money. You don’t have to pay for two separate tools because the integration combines everything into one solution.

It also cuts down on manual work, which means your team can focus on more valuable tasks. In fact, companies that invest in CRM systems usually see a strong return of about $8.70 back for every $1 spent.

3. Click to Call Right from the CRM

With click-to-call, agents can start a call by clicking a customer’s phone number directly in the CRM. No more typing in numbers or jumping between screens.

Everything is in one place: customer info, the call button, and automatic logging of the call details.

4. Post-Call Work Made Easy

After a call ends, the system automatically saves the recording and any notes into the CRM.

It can also trigger follow-up actions based on the call like creating a task if someone missed the call or sending a survey if the conversation was completed. That means less admin work for your team.

5. See What’s Working with Call Reports

You can track call stats directly in your CRM, like how many calls are happening, how long they last, how many are missed, and how quickly issues are resolved.

These insights help you see how your team is doing and where there’s room to improve, whether it’s sales or customer service.
