A sales manager pulls up the CRM at the end of the day, three calls are unlogged, two follow-ups missed, and there's no record of what was discussed on the biggest deal of the week. The team is using RingCentral. But the real problem isn't the calls; it's that the phone system runs alongside the CRM rather than inside it: call data, follow-ups, and context stay disconnected from the workflows that drive revenue.

That gap is why teams actively search for the best RingCentral alternatives. Choosing the right one isn't just a technical decision, it's a shift toward communication that's built into how your team works. Aircall replaces legacy phone systems with cloud-native AI business phone systems designed to connect every call with CRM data, automated follow-ups, and real-time visibility across sales and support operations.

What we are

Key takeaways

• Aircall replaces legacy phone systems with cloud-native AI business phone systems built around sales and support workflows

• Switching from RingCentral means evaluating both technical fit (integrations, routing) and operational alignment (workflows, team processes)

• The best alternative connects calls with CRM data, automates follow-ups, and gives managers visibility into AI-led and team-led calls in one system

• Risks like downtime and integration failures are manageable with structured evaluation and a phased rollout

• CRM-connected platforms reduce manual work, improve follow-up speed, and give managers clear visibility into team performance across every interaction

What does it mean to switch from RingCentral?

Switching from RingCentral means moving from a UCaaS-based communication system to a modern cloud business phone system that connects calls with workflows and CRM data. This includes evaluating alternatives, transferring phone numbers, reconfiguring call routing, and ensuring communication is tracked and managed across sales and support operations.

UCaaS, or Unified Communications as a Service, is a cloud delivery model that bundles voice, video, messaging, and conferencing into a single platform. Systems like RingCentral were built primarily for internal communication: connecting colleagues, hosting meetings, managing internal messaging. That's a solid foundation, but it wasn't designed with external-facing sales and support workflows in mind. When your team's performance depends on how quickly a lead gets followed up or how much context an agent has before a support call connects, internal communication infrastructure starts to show its limits.

Switching involves two separate workstreams. The technical side covers auditing your current setup, porting numbers, configuring integrations, and rebuilding call routing. The operational side, often underestimated, covers how your team's workflows, habits, and reporting dependencies need to adapt. Getting both right is what separates a smooth transition from a disruptive one.

Why businesses switch from RingCentral

Businesses switch from RingCentral when their communication system no longer supports how their teams operate, especially as workflows become more complex and customer interaction volume increases.

The patterns are consistent across sales and support teams. Outbound sales teams running high call volume manually log each outcome into Salesforce or HubSpot after the fact. When volume picks up, logging slips. Follow-ups get delayed. Speed to lead drops. Conversion rates follow. The manager can't diagnose the problem because there's no reliable call data in the CRM, the phone system and the customer record never speak to each other.

Inbound support operations face a different version of the same problem. Agents handling repeat customers have to ask them to re-explain their issue every time they call back. The helpdesk and the phone system are separate tools. There's no interaction history surfacing before the call connects, no automatic ticket update when the call ends, and no way for a manager to see first call resolution rates without manually compiling data from two different platforms.

These aren't edge cases. They're the operational ceiling that RingCentral teams hit as their workflows mature. The issue isn't the ability to make and receive calls, it's that communication runs parallel to work instead of inside it.

RingCentral vs. workflow-connected calling platforms

The key difference lies in how communication is integrated into workflows. RingCentral focuses on enabling communication, while modern call center software connects communication with data, automation, and business processes.

This is how RingCentral compares across different categories compared to more modern platforms.

CCaaS, Contact Center as a Service, is a cloud model designed specifically for customer-facing teams. Where UCaaS centralizes internal communication, CCaaS platforms are built around the customer interaction lifecycle: routing inbound calls intelligently, logging outcomes automatically, tracking agent performance in real time, and connecting to the CRM systems teams already rely on. For growing sales and support operations, this distinction is the difference between a phone system that creates work and one that reduces it.

1. Aircall

Best for: Sales and support teams that need native CRM integration and automated workflows from day one.

Aircall is built around the idea that every call should move work forward. It integrates natively with Salesforce, HubSpot, Zendesk, and 250+ other tools, automatically logging call outcomes, creating follow-up tasks, and surfacing customer history before a call connects. AI Voice Agents handle routine inbound interactions autonomously, with one-click hand-off to human agents when needed, full context intact.

Strengths:

• Native, bi-directional CRM integration with Salesforce, HubSpot, and Zendesk out of the box

• Aircall AI Agents handle tasks end-to-end autonomously (inbound and outbound calls, inbound messages) with one-click escalation to a human agent when needed

• Fast deployment, most teams are live within days, not months

Limitations:

• Primarily voice-focused; teams needing a full omnichannel suite may need additional tooling

• Best value is realized when the team has a CRM already in place to connect to

2. Zoom Phone

Best for: Organizations already deep in the Zoom ecosystem looking to consolidate video and voice on one platform.

Zoom Phone extends Zoom's familiar video infrastructure into business telephony. It works well for companies that have standardized on Zoom for internal meetings and want to bring voice under the same umbrella. CRM integration exists but typically requires additional configuration compared to purpose-built sales and support platforms.

Strengths:

• Tight integration with Zoom Meetings for unified internal communication

• Familiar interface for teams already using Zoom daily

• Solid call quality and global infrastructure

Limitations:

• CRM connectivity is not as deep or native as platforms built specifically for sales and support workflows

• Teams with complex call routing requirements may find configuration less flexible

3. Microsoft Teams Phone

Best for: Enterprises already running Microsoft 365 that want to extend Teams into a phone system without adding new vendors.

Microsoft Teams Phone adds PSTN calling capability to the Teams platform. For organizations where Teams is the primary collaboration hub, this reduces vendor complexity. The trade-off is that Teams Phone is optimized for internal communication first, connecting it meaningfully to CRM and customer-facing workflows requires additional setup and often third-party integrations.

Strengths:

• Deep integration with Microsoft 365 (Outlook, SharePoint, Dynamics)

• Single vendor for collaboration, messaging, and calling

• Enterprise-grade security and compliance controls

Limitations:

• Customer-facing workflow automation requires additional configuration or third-party tools

• Less suited to teams without an existing Microsoft 365 footprint

4. Dialpad

Best for: Teams that want built-in AI transcription and coaching alongside cloud calling.

Dialpad combines cloud VoIP with real-time AI transcription, live coaching prompts, and post-call sentiment analysis. It's a strong option for teams that want AI-assisted call management without separate tooling. CRM integration is available for major platforms, though depth of workflow automation varies by CRM.

Strengths:

• Real-time AI transcription and call summaries built in

• Live coaching prompts for agents during calls

• Clean interface with solid mobile support

Limitations:

• CRM workflow automation is less native than platforms purpose-built for sales and support

• Pricing scales quickly as AI features are added

5. 8x8

Best for: Mid-market and enterprise teams that need a broad UCaaS and CCaaS suite under one contract.

8x8 covers voice, video, messaging, and contact center functionality across a single platform. It's a good fit for larger organizations that want to consolidate multiple communication vendors. The breadth of features is a strength, but teams specifically optimizing for CRM-connected sales and support workflows may find it more complex to configure than focused alternatives.

Strengths:

• Wide feature set covering UCaaS and CCaaS in one platform

Nextiva offers reliable cloud VoIP with call routing, IVR, and basic CRM integrations. It's a dependable choice for teams that need a step up from legacy on-premise phone systems without requiring deep workflow automation. Its contact center capabilities are growing but less mature than platforms purpose-built for high-volume sales and support operations.

Strengths:

• Straightforward setup and strong customer support reputation

• Good call quality and reliable infrastructure

• Built-in basic CRM and helpdesk connectivity

Limitations:

• Workflow automation depth is limited compared to CCaaS-focused alternatives

• Less suited to teams with complex CRM integration requirements

7. Vonage

Best for: Businesses that want a customizable cloud communication platform with developer-friendly APIs.

Vonage (now part of Ericsson) offers a flexible API-first approach to cloud communications. Teams with developer resources can build highly customized call flows and integrations. For operations teams without developer support, out-of-the-box workflow automation is less extensive than with purpose-built sales and support platforms.

Strengths:

• Highly flexible API platform for custom integration builds

• Strong omnichannel capabilities across voice, SMS, and messaging

• Scalable infrastructure for high-volume deployments

Limitations:

• Realizing full value often requires developer resources to build and maintain custom integrations

• Out-of-the-box CRM workflow automation is not as deep as native-integration platforms

Preparing to switch: what to plan before choosing an alternative

Preparation ensures that switching does not disrupt operations and that the new system aligns with existing business workflows before any contracts are signed. For IT and operations teams managing the evaluation, the most important output of this stage is a clear picture of how communication currently flows, and what the new system needs to replicate or improve on.

• Audit all current phone numbers, users, roles, and permissions

• List every active integration: CRM, helpdesk, analytics, call recording tools

• Map your current call routing logic, IVR trees, ring groups, business hours, overflow rules

• Identify CRM dependencies: what triggers follow-up tasks, where call logs go, what managers use for reporting

• Flag compliance and recording requirements that must carry over to the new system

Write out what actually happens when a call comes in: inbound call arrives → routed by IVR → connects to agent → outcome logged in CRM → follow-up task created → manager reviews in dashboard. Then test each new platform against that map. The goal is to understand how communication currently flows before choosing where to move it.

Step-by-step: how to switch from RingCentral

Switching from RingCentral follows a structured process to ensure continuity, minimize downtime, and align the new communication system with business workflows.

1. Define evaluation criteria: CRM integration depth, workflow automation, call routing, and scalability

2. Shortlist alternatives that meet your CRM and workflow requirements

3. Request demos focused on real team workflows, not generic feature walkthroughs

4. Run a pilot with a small team to validate CRM integration depth and call quality

5. Plan number porting timelines and documentation with your chosen provider

6. Configure call routing, IVR, and workflow automations in the new system

7. Train teams on new workflows and complete phased rollout

Step 4 is where most decisions get confirmed or reversed. A platform that looks strong in a demo may not perform the same way when you're testing actual call routing against your real CRM data. Running a pilot before full commitment is the single most effective way to reduce switching risk.

Number porting: the process of transferring existing phone numbers from your current provider to a new one, preserving the same numbers your customers already use, requires documentation and coordination on both sides. The FCC's guidelines on number portability establish clear rights for businesses switching providers, including defined timelines carriers must meet. Starting porting early prevents it from holding up your go-live date.

How CRM-connected alternatives improve workflows over RingCentral

CRM-connected alternatives close the gap that RingCentral leaves open, every call is automatically tied to customer records, follow-up actions, and team workflows, without manual intervention.

CRM integration: the connection between a communication platform and a Customer Relationship Management system like Salesforce, HubSpot, or Zendesk, enables call data, outcomes, and next steps to sync automatically with customer records, eliminating manual logging and giving every team member full interaction context in real time. As Salesforce documents in its CRM best practices, teams that connect communication directly to customer records reduce follow-up lag and improve pipeline visibility across the entire sales cycle.

Call routing: the automated process of directing inbound calls to the right agent, queue, or team based on rules like skill, availability, language, or customer profile, becomes far more powerful when connected to live CRM data. A high-value account calling in can route directly to their assigned account manager. A customer flagged as at-risk can be prioritized in the support queue automatically, without a receptionist or manual transfer.

Workflow automation: the use of rule-based triggers to automatically initiate actions based on call events, such as logging outcomes, creating tasks, sending notifications, or updating CRM records, removes the manual steps that slow teams down and create data gaps. Teams that automate post-call processes consistently see improvements in speed to lead, average handle time (AHT), and first call resolution (FCR).

The day-to-day difference is visible immediately. A sales rep closes a call, the platform logs it to HubSpot automatically with outcome tags and a follow-up task, no manual entry required. A support agent picks up from a repeat customer, full interaction history from Zendesk surfaces before the call connects. A manager reviews weekly performance, call outcomes, talk time, and team activity are visible in one connected dashboard without exporting anything.

The results are measurable. Unbiased, the UK's leading financial advice platform, achieved a 23% uplift in service level, stabilizing at 93%, after connecting Aircall to their support workflows, all without adding a single headcount.

Common challenges when switching from RingCentral and how to avoid them

Switching from RingCentral to a new platform introduces operational risks, but these can be minimized with structured evaluation and phased execution.

The NIST Privacy Framework is a useful reference when evaluating how potential providers handle data protection during and after migration, particularly for teams operating under HIPAA, GDPR, or SOC 2 requirements. It provides a structured approach to assessing data handling practices across the full system transition.

How to choose the best RingCentral alternative

The best alternative is one that supports how your teams work daily, not just one that checks the calling features list.

The question isn't "does it support calling?", that's the baseline every platform on this list clears. The questions that actually differentiate platforms are operational:

• Does it have native, bi-directional CRM integration with Salesforce, HubSpot, or Zendesk?

• Does it automate call logging, follow-up tasks, and workflow triggers without manual steps?

• Does it give managers real-time visibility into call outcomes, agent performance, and conversation quality?

• Can it support your routing complexity, IVR, skill-based routing, business hours, overflow rules?

• Can it deploy quickly, without months of implementation work?

A platform that integrates with CRM integrations and workflow connectivity across your existing tool stack will compound value over time. One that requires manual bridges or custom build work to connect your CRM will compound friction instead.

Security, compliance, and risk management

Choosing a new communication provider requires more than evaluating features. Teams must validate how an alternative handles customer data, access controls, and regulatory compliance before committing to a switch.

Number porting is regulated. Carriers are required to process valid porting requests within defined timelines, and businesses have the right to move their numbers without penalty or delay. Understanding those rights protects you during the transition and gives you clear grounds to hold providers accountable.

Data protection during migration should follow documented practices. At minimum, confirm that call recordings, CRM data, and interaction logs are stored securely, access-controlled appropriately, and handled in line with your retention policies. For compliance and data security, Aircall maintains certifications and controls aligned with enterprise requirements, validating that your chosen platform meets your organization's standards before migration begins, not after.

Integration security is the third area to assess. Before switching, confirm that CRM access permissions and third-party connection standards meet your organization's requirements. A clean access audit before decommissioning the old system prevents security gaps that can linger long after the switch.

Getting started with Aircall

For teams that have evaluated their options and identified workflow connectivity as the core requirement, Aircall is built to meet that standard. The Aircall product overview covers the full platform, but from a switching standpoint, what matters most is that Aircall connects directly with the CRM tools your team already uses, automates call logging and follow-up tasks from day one, and gives managers visibility into every interaction without additional tooling or configuration overhead.

Aircall AI Agents handle routine inbound interactions autonomously, qualifying callers, capturing information, resolving common queries, with one-click escalation to a human agent when needed. The hand-off carries full call context, so agents never start from scratch. Browse customer success stories to see how sales and support teams have made the switch and the outcomes they've measured.

The automation and AI summaries built into the platform reduce post-call admin for agents, giving them more time on the next conversation and less time updating records manually. For a full breakdown of what's included at each tier, see Aircall's pricing plans.

Frequently asked questions

What is the best RingCentral alternative for business?

The best alternative depends on how your teams work. For sales and support teams that need CRM-connected communication, a platform that natively integrates calls with workflows will outperform a standard UCaaS system like RingCentral.

Can you keep your phone numbers when switching from RingCentral?

Yes. Businesses can port existing numbers to a new provider with proper documentation and coordination. Carriers are required to process valid porting requests, so you keep the numbers your customers already use.

What should you evaluate before switching from RingCentral?

Audit current users, numbers, integrations, and workflows. Map how communication flows across systems and identify CRM and helpdesk dependencies. The more detailed your pre-switch documentation, the smoother the new platform setup will be.

What are the risks when switching from RingCentral?

The main risks are selecting a platform without validating CRM integration depth in a live environment, and underestimating the workflow reconfiguration required. Running a structured pilot before full rollout significantly reduces both.

What is the best RingCentral alternative for CRM-connected teams?

For teams using Salesforce, HubSpot, or Zendesk, the best alternative automatically logs calls, surfaces interaction history before calls connect, and creates follow-up tasks, without manual input from agents.

Making the right call: choosing an alternative that fits how your team works

Choosing the right RingCentral alternative is a long-term system choice that shapes how sales and support teams communicate, coordinate, and execute every day.

The right platform connects communication directly with CRM data and business workflows, gives managers real-time visibility into calls and outcomes, and scales with growing call volume without adding manual coordination overhead. Teams that move to workflow-connected platforms reduce manual logging, improve follow-up speed, and create a more consistent experience for customers across every interaction.

Aircall supports this shift by replacing standalone phone infrastructure with a communication system that is natively connected to the tools, data, and processes your teams already use. If your team is ready to move from comparison to implementation, reviewing how your new platform connects with existing CRM and support workflows is the right next step.
