Features, Pricing & User Feedback
Exploring Five9? Discover what real users say about call quality, features, and support—plus see how CloudTalk compares.
What is Five9?
Five9 is a publicly traded enterprise CCaaS leader known for high-volume outbound Campaigns. Its acquisition of Acqueon reinforces a legacy built on a massive Parallel Dialer architecture designed for large-scale revenue execution and proactive outreach.
The 2025 Genius AI suite introduces autonomous AI Voice Agents and Agentic Quality Management. Using Sentiment Analysis to drive ROI, Five9 serves as a top-tier choice for massive contact centers needing complex omnichannel engagement.
A 50-seat minimum and $600/seat fully-loaded costs exclude many mid-market teams from Five9's ecosystem. Growing businesses often prefer the agile Call Flow Designer and transparent Pricing model of a unified, mid-market-focused stack.

What Users Say About Five9
Based on 900+ verified reviews from G2, Capterra, and Trustpilot
😊 What Users Love
- Salesforce integration depth is market-leading — agents work entirely within the Salesforce UI without screen-switching
- Robust, customizable reporting praised by enterprise reviewers
- Genuine scalability for high-volume operations — Five9 supports deployments of 10,000+ agents
- AI features — summaries, Agent Assist, AI Knowledge — landing well at enterprise scale
"I really appreciate the rock-solid reliability and clear call quality. We rarely experience any downtime, which is absolutely crucial for keeping our support team running."
😤 What Users Hate
- Implementation routinely runs around 2 months — significant professional services investment required
- Pricing opacity and sticker shock — published $119–$159 frequently lands at $300–$600 fully loaded
- Automatic logout after ~5 minutes of inactivity — frustrating for support agents juggling tools
- Agent UI complexity — described as "not the most intuitive" for new agents during onboarding
- 50 concurrent seat minimum — sub-50 agent teams cannot purchase the platform
"I use Five9 every day, all day. The stability of calls has dropped over the last few years. I have used Five9 for over 15 years and it has declined significantly. No customer service aside from basic responses, their servers are down consistently without warning, without any updates or alerts. If you need a stable call connection, i would never recommend Five9"

Senior Client Services Manager
Calls appear to be clear and the reporting is decent. The system often put users on not ready with no reason why."
Tech Support
Good sales process. Helpful salespeople. They try to sell you on the holistic platform and they do a great job about it. Once you get into the platform itself you see that what you were sold is a mirage."

Why Choose CloudTalk Over Five9
The six capabilities AVOXI customers tell us they wish they'd had on day one.
Businesses That Switched to CloudTalk
Real results from real companies that made the move—and never looked back.
“In the old platform, there was no automatic ticket creation. We had to manually check the logs to see which calls were missed and whether they were followed up. It made it difficult to track exactly how many calls we missed or managed to handle.”
“Once we switched to CloudTalk, our missed calls dropped by 23%. That’s not just a number; that’s customers we’re able to connect with before it’s too late.”
Vendor Operations Manager at Aspire
“We didn’t have trustworthy data. Reports didn’t match, calls weren’t recorded properly, and even billing discrepancies became a recurring issue.”
“With CloudTalk, we finally have visibility. We can see which teams are handling calls and whether they’re the right ones for the job. That allows us to rebalance workloads.”
Customer Experience Coordinator at Alura
“We were stuck at a 20–30% pickup rate with Aircall. With CloudTalk, we’ve hit 40–50%. That’s made all the difference.”
"We use the tag feature a lot to track where leads are in the funnel. And the dashboard helps each rep see where they’re at."

Frequently Asked Questions
Five9 is an enterprise-first platform designed for massive operational complexity. The 50-seat floor exists because their model relies on a managed implementation process and professional services that aren't tailored for smaller teams. For businesses with fewer agents, the pricing model of a mid-market specialist offers much more flexibility without mandatory seat requirements.
The $119 Digital bundle is restricted to non-voice channels like chat and email. The $159 Core bundle adds voice but limits AI features to a 3,000-minute cap per seat. High-growth teams often prefer a Power Dialer or Parallel Dialer that scales with their volume rather than facing consumption-based overages on every call.
Deploying Five9 is an enterprise-scale program that averages two months of configuration and training. If your team needs to be operational quickly, a browser-based Call Flow Designer and native CRM connectors can get you taking live calls within a single week rather than a full quarter.
Five9 offers a very deep, Salesforce-first architecture suited for massive enterprise environments. CloudTalk provides a native Salesforce
integration that supports Click-To-Call and real-time data sync, which covers the essential workflows for most mid-market teams without the six-figure implementation price tag.
The switch usually happens when teams hit the 50-seat floor or want to avoid capped AI minutes. Most organizations prefer AI Smart Notes
and Automatic Call Summary Tags that apply to 100% of their calls, alongside an agile interface that doesn't require a dedicated IT function to manage.
