2. Dialpad

Embedded image

Unless you’re new to the VoIP telephony market, you’ll surely have heard of Dialpad. It’s a reliable, unified telephony solution with simple built-in AI and advanced analytics. A live chat, phone hotline, and knowledge base make it a great deal for customer support teams.

Dialpad’s benefits:

Dialpad’s main advantages are voice intelligence and uptime, which are between 99% and 100%. You’ll get conference video calls, sentiment analysis, voicemail transcriptions, call tracking metrics, Speech-to-Text for an automatic call recording, and much more.

With Dialpad, you can call the US and Canada for free and from anywhere in the world. Inbound and outbound calling within your country is also free of charge. The provider has a modern, well-organized UI, plenty of training videos, and a well-built mobile application.

Key features:

  • Call Recording
  • Machine Learning
  • Call Analysis
  • Customer Scoring
  • Call Routing

What is Dialpad missing?

While Dialpad offers a Power dialer, it lacks a Smart and Predictive dialer. The Power dialer feature is limited, as it only works with Salesforce. Unlike the CloudTalk app, the Dialpad app only allows users to dial phone numbers manually.  Also, the Preferred agent feature only works through API.

Dialpad also lacks a visual flow editor for its Call flow designer. Furthermore, you can’t send SMS messages outside of the US and Canada, although this feature will soon become available to those in the UK.

The provider offers a limited integration stack, and Voicemail drop comes only with Dialpad Sell.

What type of business is it best for?

Any size of sales organization looking to drive agent efficiency and speed up ramp times.

Pricing: From $15/user/month

G2 rating: 4.4/5

3. Nextiva

Embedded image

Nextiva is a big player in the VoIP market, providing services to more than 15,000 customers. Nextiva is widely regarded as user-friendly — users can start calling within minutes thanks to a simple and intuitive setup process. Furthermore, the system is hosted by Nextiva, which makes maintenance of the software Nextiva’s responsibility.

Nextiva’s benefits:

Nextiva offers various advanced features, including conference calling, voicemail transcription, multi-level attendant, and much more. The provider also integrates with solutions like Zendesk, ConnectWise, or MS Teams.

Nextiva’s HIPAA-compliant virtual faxing makes it a great solution for healthcare workers. Medical employees can share information without having to worry about data breaches. Furthermore, 24/7 support means agents are always on hand to assist you.

Key features:

  • Unlimited Calling
  • Video Conference Recordings
  • Mobile & Desktop Apps
  • Workflow Optimization
  • Omnichannel Communication

What is Nextiva missing?

Although Nextiva is a well-known VoIP solution, there are some issues you should know about when considering this provider:

  • Prices: Many consider Nextiva’s prices high, especially for small businesses.

What type of business is it best for?

Businesses need a robust, secure, and reliable enterprise phone system that works across every device and has advanced features like video conferencing, mobile apps, call recording, and more.

Pricing: From $20/user/month

G2 rating: 4.4/5

4. 8×8

Embedded image

8×8 is an evergreen telephony solution focusing on integrations and analytics. The provider is well-suited for enterprises, but lower-tier subscriptions also work for smaller organizations. There are many benefits 8×8 can offer its subscribers.

8×8 benefits:

First of all, the provider has done a great job building an Analytics system that can effectively track large-scale business processes. 8×8’s reporting system centralizes all data in a single place, so managers can make their teams more organized and speed up their workflow. You’ll also get real-time reports.

Then, we have the solution’s comprehensive integrations with software like Salesforce, Slack, Microsoft Teams, and many more. Furthermore, 8×8 users get unlimited calling to 40+ countries. 8×8 telephony software comes with a smart dialer, click-to-call, and call recording.

Key features:

  • Call Center Management
  • IVR
  • Contact Management
  • Analytics & Reporting
  • Call Monitoring

What is 8×8 missing?

If you own a business that works globally, there are a few things about 8×8 you might want to consider:

A crucial restriction, mainly for big international companies, is that there are regional constraints on unlimited calling. Users with the basic Express plan can only use unlimited calling in the US and Canada.

  • MS Office is required: You need an office where you want to call to get a number from there.
  • Geographical restrictions for SMS: You can only use the SMS feature within the US, and 8×8 does not cover costs for mobile numbers in Brazil.
  • Integrations: 8×8 doesn’t partner with telco companies, so users won’t have native integration with specific solutions like WhatsApp. Non-native integrations must be set up by the tech team.
  • Features: 8×8 lacks features like call tagging for more efficient calling processes, call masking for protecting your personal information, and API for connecting with the tools you love. Automation tools like IVR, skills-based routing, or automated callback come only with high-tier plans. You have to pay extra to get a call recording.

What type of business is it best for?

8×8 is generally considered a very flexible for any type of business.

Pricing: Per request

G2 rating: 4.2/5

5. RingCentral

Embedded image

When you think about VoIP telephony solutions, RingCentral is among the first ones that come to mind. It’s no wonder the company has been on the market for over 20 years and has built quite a reputation.

RingCentral’s benefits:

RingCentral has a great variety of features and offers HD-quality voice and video. The provider is a good fit for enterprises since it provides an omnichannel experience, lead qualification tools, management, collaboration, and performance features – all in a single software.

Key features:

  • SIP Trunking
  • IVR
  • Call Recording
  • Call Routing
  • Contact Management

What is RingCentral missing?

Despite all the positives, RingCentral lacks many essential tools that modern businesses require.

Features like native sentiment analytics, speech-to-text transcription, smart dialers, and skill-based routing are only included in Contact Centre Solution. The same goes for some agent management features, like monitoring.

The Call recording tool and Toll-free numbers are only available as add-ons for an additional cost.

Furthermore, RingCentral’s implementation can take as much as 90 days and involves an implementation fee.

RingCentral UI is also not always the friendliest to work with.

What type of business is it best for?

RingCentral MVP is a flexible cloud-based solution ideal for businesses of all sizes.

Pricing: From $20/user/month

What type of business is it best for?

Ooma is best for smaller businesses looking for a basic VoIP service.

Pricing: From $19.95/user/month

G2 rating: 4.4/5

7. Vonage

Embedded image

Vonage is among the best-known virtual phone providers in the world. They’ve been in the business for over 20 years and have established an enviable market leader reputation.

Vonage’s benefits:

  • The Virtual Receptionist, automatic attendant feature, allows calls to be forwarded to other departments.
  • Moreover, businesses can provide callers with alternatives for call routing that let them use either their name or an extension to dial. Before having their calls routed to a department, callers can also use the company directory.
  • Even when businesses use cloud services that consume a lot of bandwidth, such as collaboration, chat, and video tools, Vonage’s network optimization features ensure call continuity and call quality.

Key features:

  • Stability and reliability
  • Auto-attendant
  • CRM integrations
  • Voice and video conferencing
  • Call forwarding services

What is Vonage missing?

Unfortunately for customers, Vonage has capitalized on its reputation by charging much more for its services than other comparable virtual phone software providers.

Vonage pricing also includes many hidden fees that make the service far more expensive than expected.

This can be a real downside for small businesses that need to be more discerning about how and where they expend their resources.

What type of business is it best for?

Vonage is best for companies looking for a well-established provider.

Pricing: From $17.99/user/month

Key features:

  • Automatic Call Distribution
  • Call Monitoring
  • Call Transfer

What type of business is it best for?

Aircall is a calling software primarily targeted at small businesses using the phone to conduct sales and support business daily, but certainly not all of them. Think about how frequently your team uses smart dialers. You might consider looking elsewhere if they’re a core part of your day-to-day work.

Why Should You Use A Dialer For Cold Calling?

After teasing the topic in the previous section, it’s only right that we dedicate some time to fully exploring the benefits of using an outbound dialer. Here’s what you can look forward to after onboarding any type of ADS into your operations.

1. Improve Operational Efficiency

Sales dialers significantly increase the efficiency of sales teams by automating the dialing process. Instead of manually dialing each number, agents can focus on engaging with prospects, leading to 3x more calls per day and more opportunities for conversion.

2. Increase Customer Satisfaction

By streamlining the calling process, the best sales dialers for cold calling enable agents to spend more time building relationships with prospects. With features like call recording and CRM integration, agents can personalize interactions and provide better service, ultimately improving customer satisfaction and retention and reaching up to a 50% increase in leads and appointments.

3. Boost Conversion Rates

Outbound dialers help manage leads more effectively by organizing contact lists, scheduling follow-up calls, and tracking interactions. This structured approach can offer a 98% accuracy in verifying numbers and ensures that no lead falls through the cracks, resulting in higher conversion rates and revenue.

4. Reduce Agent Idle Time

With outbound dialers, agents spend less time waiting between calls, as the system automatically dials the next number as soon as they are available. This minimizes idle time and keeps agents productive throughout their shifts.

5. Ensure Compliance & Security

Outbound dialers are equipped with features to ensure compliance with regulations such as the Telephone Consumer Protection Act (TCPA) and Do Not Call (DNC) lists. Dialer software helps mitigate the risk of non-compliance and potential legal issues by automatically screening numbers and recording consent.

Cold Calling Dialers Explained: Types & Use Cases

The world of sales dialers is wide and varied, and it can be difficult to make sense of all the different types. Below, you’ll find a summary of the 6 most common types of cold calling dialers to help get started with finding the best one for you.

TL;DR:

Here’s a sneak peek at the best cold calling dialer types we’ll cover in this section:

  • Power Dialer — best for personal sales at scale
  • Parallel Dialer — best for fast, high-volume outreach
  • Smart Dialer — best for CRM-driven calling
  • Preview Dialer — best for prepped, detailed conversations
  • Predictive Dialer — best for mass campaigns (but risky for compliance)

Keep reading to see how each works, their pros and cons, and which one fits your team best.

1. Power Dialers

Power Dialers automatically dial one number at a time from a pre-defined list of contacts once an agent becomes available. This system provides greater control over assigned call queues.

They can also come equipped with features like Call Recording, Analytics, on-screen scripts, and CRM integrations. This makes them ideal for businesses running time-sensitive promotions or managing emergency notifications efficiently.

Best For: Balanced call campaigns optimized for both reach and personalization. Operations where call quality, follow-up, and detailed interactions are essential.

Power Dialer Pros & Cons

ProsCons
Increases productivity by automating dialingAgents may experience idle time waiting for connected calls
Ensures agents handle only connected callsLess efficient for extremely high-volume call scenarios
Easy to implementInability to call several numbers simultaneously

2. Parallel Dialers

Embedded image

A Parallel Dialer dials multiple numbers simultaneously (up to 10!), connecting the first answered call to an available agent.

Unlike a predictive dialing mode (more on that in a bit), which uses algorithms to anticipate agent availability, a Parallel Dialer operates on direct commands to place multiple calls at once, providing a more straightforward approach to managing automated outbound calls.

And the best about this dialing mode? It helps you detect answering machines, so your agents save even more time they can invest into calls that truly move the pipeline.

Best For: Large-scale operations conducting high-volume outreach campaigns where speed is critical.

Parallel Dialer Pros & Cons

ProsCons
Increases call volume and agent productivityIf improperly managed, it can increase dropped calls
Detects voicemails in less than 1.5sRequires refined management to optimize performance
Maximizes efficiency for high-volume outreach campaignsThe speed of the outreach comes at the cost of context

Stop Wasting Time on Voicemails

With CloudTalk’s Parallel Dialer, your agents can finally listen to your customers, not their AMDs.

3. Smart Dialers

Smart Dialers are advanced systems designed to automatically gather numbers from CRM platforms or websites and queue them for dialing. When paired with a Click-to-Call tool, this system empowers agents to dial through their lists with greater efficiency and speed.

Best For: Businesses that rely on CRM systems and online customer prospecting, aiming to automate phone calls to enhance efficiency and boost productivity in large-scale sales operations.

Smart Dialer Pros & Cons

ProsCons
Easy Customization by ordering numbers through drag-and-dropWorks better when integrated into a CRM system
Increases agent productivity, eliminating manual dialingRequires a click-to-call feature to optimize the outbound calling system
Provides contextual data for personalized callsRequires robust management to optimize performance

4. Preview Dialers

Just like Power Dialers, Preview Dialers focus on dialing one contact at a time. The difference? They don’t just fire off calls in sequence. Instead, a Preview Dialer waits until the agent is ready before starting the next call.

The next call can either be chosen by the tool or triggered manually by the agent, giving you more control over the pace and flow of calls.

Best For: Call campaigns that aim to balance broad reach with personalized engagement. Scenarios where customized and detailed interactions cannot be overlooked, such as B2B campaigns.

Preview Dialer Pros & Cons

ProsCons
One call per agent helps prevent dropped callsGiving agents control over initiating calls can impact overall productivity
Balance efficiency while giving agents time to prepareLonger time during the connection process, impacting overall efficiency
Easy to implementLess efficient for extremely high-volume call scenarios

5. Predictive Dialers

Predictive Dialers are automated systems that anticipate when an agent will be free and start dialing multiple numbers before the current call finishes. They use advanced algorithms to predict when the agents will become available and connect them only with answered calls.

This way, when the agent hangs up, another call is ready to go.

Best For: Large-scale operations focused on efficiency and throughput, such as collections, market research, or any environment where quick connections and high call volumes are prioritized over the quality of individual calls.

Predictive Dialer Pros & Cons

ProsCons
One call per agent helps prevent dropped callsGiving agents control over initiating calls can impact overall productivity
Balance efficiency while giving agents time to prepareLonger time during the connection process, impacting overall efficiency
Easy to implementLess efficient for extremely high-volume call scenarios

Predicting Trouble Ahead

Predictive dialers might look like the fastest way to reach more leads—but they often cause dropped calls and compliance headaches. That’s why CloudTalk no longer offers this dialing mode: it can risk your team’s reputation and expose your business to legal penalties. Want to reach many leads fast, but also stay compliant? Then use the parallel or power dialing mode.

How to Choose the Best Dialer for Cold Calling?

As should be clearly evident, despite sharing the same designation as sales AI dialers, each type is very different. If you want to find the one that’s right for you, you’ll need to consider the following aspects of your business.

1. Assess Your Business Needs and Goals

Before investing in an outbound dialer, take the time to assess your business needs and objectives. Consider factors such as the size of your sales team, the nature of your outbound campaigns, and your target audience.

Are you focusing on high-volume cold calling, or do you prioritize personalized interactions with leads?

Understanding your unique requirements will help you narrow down your options and choose a dialer that meets your business goals.

2. Understand Your Call Volume & Agent Capacity

Evaluate your call volume and agent capacity to determine the scalability and efficiency requirements of your outbound dialer.

If you anticipate high call volumes and have a large team of agents, you may benefit from a predictive dialer that can automatically adjust dialing rates based on agent availability.

Conversely, if you have a smaller team or variable call volumes, a progressive or power dialer may be more suitable for pacing calls to match agent capacity effectively.

3. Look for Must-Have Features

Depending on the size and goal of your call center, you should prioritize providers with different sets of features – whether they be automation for outbound or inbound calls, personalization, analytics, or something else.

Write down a list of features that you absolutely must have and go through your list of potential solutions. Make sure to keep a close eye on where they fall in the pricing plans, as some might be locked behind higher tiers.

4. Consider 3rd Party Integrations

Integration with your existing CRM (Customer Relationship Management) and software platforms is essential for seamless operations and data management.

Choose an outbound dialer that offers robust integration capabilities with popular CRM systems, such as Salesforce, HubSpot, or Zoho CRM. CloudTalk offers more than 35!

This ensures that your sales team can access relevant customer information, track interactions, and sync data effortlessly, streamlining workflow and enhancing productivity.

5. Keep an Eye on Compliance

Compliance with regulatory requirements, such as the Telephone Consumer Protection Act (TCPA) and General Data Protection Regulation (GDPR), is paramount when selecting an outbound dialer.

Ensure that the dialer software you choose is equipped with features to support compliance, such as automatic DNC (Do Not Call) list scrubbing, call recording consent management, and opt-out mechanisms.

Additionally, prioritize data security by selecting a dialer that offers robust encryption protocols, secure data storage, and regular security updates to safeguard sensitive customer information.

6. Consider Your Budget

There’s a lot you need to account for when trying to establish how much the best cold calling software will cost you. The type of provider (PBX vs. cloud-based), features, integrations, and numbers all have a part to play.

Some things a lot of first-time buyers fail to account for are the correlation between pricing plan and the number of users (pricing is usually per user), billing method (monthly vs. annual), actual call and SMS costs, and additional hardware (microphones, phones, laptops, etc.). Don’t make the same mistake!
