Avaya vs Mitel Deep Dive: Which Wins in 2024

If you have a hybrid workforce, then you know first-hand how difficult collaboration can get. In my own experience – messages easily get missed or ignored, time zone differences slow the project execution, and remote workers feel left out of important conversations. 

No amount of Slack chat messages or emails can fix these issues.

Phone calls or video calls however seem to help with most of these. There is something about human connection over voice which clarifies and improves communication.

Chances are, just like me, you are looking for a business phone system that can help you streamline communication for your distributed workforce. And you’ve come across two popular solutions on the market: Avaya and Mitel

A great place to start, no doubt. But bear in mind that these phone systems have limitations that can slow down communication and collaboration for your distributed workforce — we’ll discuss them shortly.

My Final Verdict: 

Both Avaya and Mitel are established unified communications providers with a wide range of features and solutions. However, when compared to the alternative solutions we listed below, plus live data from G2 customer reviews, Nextiva stands out.

  • Nextiva (G2 rating: 4.5/5 stars from 2,822 reviews) offers several advantages over both:
    • Avaya (G2 Rating 4.1/5 stars from 176 reviews)
    • Mitel (G2 Rating 3.8/5 stars from 228 reviews)

Here are the main Nextiva advantages over Avaya and Mitel:

  • Better customer reviews per data above
  • Superior customer service: Nextiva is consistently praised for its Excellent Customer Service, available 24/7 via phone, chat, and email.
  • Ease of use: Nextiva’s platform is easy to set up and use, even for businesses with limited IT expertise.
  • Comprehensive unified communications features: Nextiva offers a wide range of features, including VoIP calling, video conferencing, team collaboration, and customer relationship management (CRM).
  • Affordable pricing: Nextiva offers competitive pricing plans that scale to meet the needs of businesses of all sizes.

Overall, Nextiva is the preferred unified communications provider for most businesses. However, it’s important to note that the best unified communications provider for your business will depend on your specific needs and budget. Be sure to evaluate all of your options carefully before making a decision. That’s why we’re here to help.

  • Seamless integration with Avaya’s ecosystem apps and third-party tools

The problem Avaya solves for businesses is:

Here are some G2 reviews backing up these statements above:

Main pros:

In one user’s words:

What I like best about Avaya is that it is very easy to use. I can answer calls with just one click. I can also customize it by adding buttons or numbers for auxiliary mode. I really like the fact that the audio is clear. You can use any kind of headset since it is compatible with any type. This communication tool allows us to contact our clients all over the world. 

Another user noted that Avaya made the transition from in-office to remote work smooth for his team. 

I like the simplicity of Avaya. It was so simple to use, and I was able to learn in under an hour. I never had a single issue when using this program. This came in very handy when my company shut down in-office work, and we had to move to remote working. My team was able to install it within a day’s notice, and we did not miss a beat.

Main cons:

Many users struggle with understanding Avaya’s setup and functions. Here is a review from another user: 

“It’s too complicated to set up, especially if you are a new user. You will not know how to change the toggle from LUNCH to BREAK and AUTO in,” 


Mitel G2 Rating 3.8/5 Stars 

Mitel has an overall rating of 3.8 out of 5 stars from 228 reviews on G2.

Analyzing these 228 reviews the following facts stand out:

  • Mitel’s contact center solutions helps organizations manage customer interactions efficiently. These solutions include features such as automatic call distribution (ACD), interactive voice response (IVR), and workforce optimization tools

Here are some G2 reviews backing up these statements above:

Main pros:

“I like that the Mitel Micollab allows us to do so many things. We can set up recurring or individual conference calls, we can use the chat (instant messenger) function, or we have regular VOIP phone service. The setup is simple — just plug it in! User instructions are quite easy for staff to follow when it comes to voicemail, messaging, etc., and the actual hard copy guide has step-by-step instructions you can just pass on,” explains this user

Main cons:

The biggest con for Mitel users is poor and unresponsive customer support. According to one user,

“It has taken over a month for them to simply help me modify our call tree and add on-hold music with a message. The on-hold music still has not been implemented.” 

We also checked out Nextiva to see how its reviews stack up against Mitel and Avaya.

Here’s how one user describes their experience with Nextiva so far:

“Customer Service is great! And the setup is so easy, and they walk you through it instead of handing you a guide. Whenever you run into an issue, which so far for us is hardly ever, you can rely on technical support to fix the issue immediately. Also, our phones have never been down, which is something we experienced frequently with our last provider. We are happy with the switch!

We’ll share a bit more about Nextiva later in this article.

Mitel vs Avaya: Features Comparison

Now that you have a basic idea of how these software applications work, let’s see how they square up against each other.

Unified communications

Takeaway: Mitel has more robust unified communications tools then Avaya.

Mitel has a slight edge over Avaya here. Its products wrap several voice and collaboration apps into one powerful business communication platform. 

Take MiCloud Connect, for example. It has over 15 voice, video, and instant messaging software, letting you coordinate your communication workflow from one central app.  

Avaya’s products aren’t as robust as Mitel’s, although they offer core communication features like video conferencing and voice calls. For example, you need to maintain separate profiles for the web portal, phone, and voicemail, which defeats the purpose of having a centralized communication network in the first place.

Contact centers

Takeaway: Avaya provides a more robust suite of contact center tools compared to Mitel.

Avaya offers AI-powered contact centers. For example, you can route calls to Ai-agents trained to have human-like conversations with customers. On top of that, Avaya AI blocks background noise in voice calls, so you can have and record clearer conversations with customers.

Mitel, on the other hand, gives you more than call center functions. It provides data to help call agents identify and explore account expansion opportunities early, contributing to revenue growth. It also serves as a workforce management tool, allowing you to assign tasks to call center agents, view overtime availability, and approve leave requests in the app.

Both business phone services help you scale your call centers efficiently.

Collaboration tools

Takeaway: Avaya and Mitel have similar communication capabilities. But we’ll give Mitel the win here because it’s much easier to set up and use compared to Avaya.

Avaya and Mitel do an excellent job here. With Avaya Spaces, you can view your projects, messages, and tasks in one place. You can also transfer, merge, and manage calls across multiple platforms, host video meetings, and share files directly from the app. 

MiCollab, Mitel’s collaboration tool, syncs with your calendar so you can view upcoming events in the app. You can send broadcast messages to your team, manage documents, and host video conferences on your PC, Mac, and smartphone.


Deployment Options Compared

Takeaway: It’s much easier to deploy Mitel’s phone system compared to Avaya.

Avaya and Mitel both offer on-premises, hybrid, and cloud deployment, meaning you can use them anywhere.

In terms of ease of deployment, Avaya has a 4.1 Gartner rating compared to Mitel’s 4.3 rating on the same user review site. Some Avaya users say its deployment instructions are unclear, and they have to repeatedly reach out to the support team to set things up and upgrade the phone system.


Integration Compared

Takeaway: Overall, Mitel seems to offer more pricing flexibility for small businesses compared to Avaya.

When choosing a phone system for your business, you want something that integrates with the tools you already use to run your business. The last thing you need is to invest in a phone system and realize that you must change your entire workflow to use it.

Avaya and Mitel have native app ecosystems for their products. For example, Avaya Social Media Hub integrates with contact center solutions like Avaya Oceana. And MiCollab syncs with MiTeam

Mitel has 48 third-party integrations in its app store, including CRM tools like Salesforce and customer experience management platforms like Zendesk. Avaya integrates with up to 29 apps, including Cherwell and Zoho CRM. 

Honestly, these aren’t enough. But the good thing is you can always use their APIs to create custom integrations for your business needs. You’ll need some coding knowledge to pull this off, though.


Pricing and Licensing Compared

Takeaway: Mitel seems to offer more pricing flexibility for small businesses vs. Avaya.

Avaya does not have off-the-shelf pricing for any of its products. So, you need to reach out to their sales teams for custom quotes based on your unified communications needs. 

Mitel has four pricing plans for its MiCloud Connect product. The cheapest package costs $20.99 per user/month, while the Elite package costs $38.49 per user/month. It also offers four subscription-based packages for MiVoice Office 400. 

Other Mitel products have custom pricing plans, so you need to contact the sales team for a quote. 

Both Mitel and Avaya offer perpetual, subscription, and cloud-based licenses. Avaya subscription comes with 20% stretch usage for free, plus discounts on trade-ins of current licenses. Mitel subscription, on the other hand, lets you customize your product offering, so you only pay for features and licenses you need. 

Overall, Mitel seems to offer more pricing flexibility for small businesses compared to Avaya.
