The best Zoom Phone alternatives depend on the work you need to improve. RingCentral and Nextiva are relevant for wider business communications, KrispCall for shared customer calling and supported international numbers, and Dialpad for AI-assisted calling or dedicated sales and support products. GoTo Connect, Quo, Calilio and CallHippo offer additional options for specific office or customer-phone requirements.
Zoom Phone is already a capable cloud phone system, especially for employees who use Zoom. Switching makes sense when another provider offers a clearer fit for your customer workflow, required numbers, administration or complete cost. A longer feature list alone is not enough reason to move.
This guide compares eight alternatives, explains the trade-offs and outlines a practical migration checklist. Recommendations reflect documented product scope and business requirements; they are not claims of firsthand performance testing.
Why Businesses Look for Zoom Phone Alternatives
Start with the problem that triggered the search. A sales manager needing campaign dialing, a receptionist managing holiday routing and an owner wanting shared customer texts have different priorities. Treat each as a workflow to demonstrate.
- Customer handover: Several employees need access to the same caller history, notes and follow-up responsibility.
- Sales processes: Representatives need a particular dialer mode and accurate CRM activity.
- Phone administration: The proposed service should make departments, permissions and routing manageable.
- Number requirements: Confirm a particular country, number type and messaging capability.
- Total cost: Compare seats, numbers, destinations, add-ons and subscriptions that will remain.
Do not assume Zoom lacks a capability simply because the current account does not use it. Check its eligible licenses and add-ons first. Then compare that working configuration with the alternative quote.
Our VoIP vs UCaaS guide explains how a phone-focused service differs from a broader communications suite.
Best Zoom Phone Alternatives at a Glance
The order provides a practical shortlist rather than a universal performance ranking. Choose the providers that match your unmet requirement.
| Provider | Consider It For | Main Trade-off |
|---|---|---|
| RingCentral | Communications across departments and locations. | RingEX and contact-center products have different scope. |
| Nextiva | Office calling with customer-engagement options. | Required tools depend on the eligible package. |
| KrispCall | Shared customer history, international-number requirements and eligible sales tools. | Verify plan, allowances, CRM behavior and AI add-ons. |
| Dialpad | AI-assisted calling and sales/support products. | Connect, Sell and Support are separate comparisons. |
| GoTo Connect | Office routing with meetings and messaging. | Regional allowances and advanced agent tools need checking. |
| Quo | Small teams sharing calls and customer texts. | Numbers focus on the US, Canada and North American toll-free options. |
| Calilio | Phone-focused service and supported international numbers. | Confirm feature tier, user limit and usage. |
| CallHippo | Dedicated sales calling and CRM/dialer requirements. | Quote the exact product and dialing mode. |
1. RingCentral: Broader communications across departments and locations
RingCentral RingEX combines calling, messaging, video meetings, business SMS and fax. It is a relevant Zoom Phone competitor when several offices or departments need a common communications environment.
Why consider switching: You want to evaluate centralized administration and collaboration alongside phone handling. A growing business with separate sales, operations and reception teams should compare how users, permissions and departmental calls are managed.
The trade-off: RingEX does not automatically include the full capabilities of RingCentral’s contact-center products. Advanced shared customer messaging can also depend on the bundle or add-on. Internal team chat is not equivalent to a customer SMS inbox.
Test before buying: Build a sales queue, route an unanswered call to a backup department and have two employees handle the same customer message. Ask the salesperson to identify the exact license and add-ons used in the demonstration.
May not suit: A small business that needs only shared calls and texts and would use little of a broader suite. Request a current quote for the required product rather than assuming the lowest RingCentral plan replaces every feature in your current setup.

2. Nextiva: For Business Calling and Customer Communication
Nextiva’s small-business offering combines voice, video, business SMS, routing and team communication tools. It is worth evaluating when the goal is to connect your office phone service with other employee or customer interactions.
Why shortlist it: Your team wants business calling within a wider communication environment and needs to compare how different feature tiers support customer handling.
Main trade-off: The Core plan and higher customer-engagement packages are not interchangeable. Confirm your required recording, reporting, messaging allowances and integrations against the quoted tier.
Demo task: Route a call during business hours, handle an unanswered call, send a customer follow-up and locate the interaction afterwards. Check whether each step is available in the proposed plan.
Pricing context: Obtain the eligible plan, billing term and complete quote. Nextiva’s advertised small-business offer has eligibility and agreement conditions; it is not an enterprise contact-center rate.
May not suit: A buyer whose main requirement is a specialized outbound sales workflow that has not been demonstrated.
See our Nextiva review.
3. KrispCall: For Shared Calling, International Numbers and Sales Workflows
KrispCall deserves a closer look than a simple “cheap international number” description. Its offering combines a Unified Callbox with phone routing, customer messaging, CRM connections and plan-specific sales tools. It can be relevant to a small customer-facing team or a growing sales operation, provided the eligible package covers the work.
What the Unified Callbox Adds
The Unified Callbox brings calls, messages, voicemail and customer context into one workspace. The practical value is continuity: an employee can review the conversation before following up instead of searching separate records. Shared access, notes and tags should be demonstrated with the actual team permissions.
Example: A customer calls while the account owner is unavailable. Another employee reviews the existing conversation, adds a note and handles the follow-up. During evaluation, check whether the second employee can see the necessary context and whether responsibility remains clear.
Sales Tools and CRM Connections
KrispCall markets a sequential power dialer for working through outbound lists. Sequential dialing is different from parallel or predictive dialing; do not assume it reproduces the specific dialer mode you require.
Its HubSpot integration describes contact synchronization and call activity logging. The useful comparison is whether your contact match, notes, ownership and follow-up appear correctly in your CRM configuration. Ask for a live demonstration, including duplicate contacts and missed calls.
For an outbound team, test importing a small list, placing calls, recording outcomes and reviewing the resulting CRM activity. Ask how unsuccessful calls and retries are handled, and which license is required.
Choose the Eligible KrispCall Plan
The current plan names are Starter, Advance, Max and Enterprise. The annual per-user monthly rates displayed are $12, $32 and $48 for the first three. Starter allows up to five users, Advance up to 50, and Max has no member cap. Enterprise is quoted separately.
Advance’s plan summary adds recording, transfers, a power dialer, bulk SMS and Salesforce integration. Call transcription and summaries are marked as add-ons. A team needing those functions should compare the relevant Advance or higher quote rather than assuming Starter supplies the complete replacement.
International Numbers and the Real Usage Bill
Confirm the exact country, number type, document requirements, caller ID and messaging capability before paying. A global-coverage headline does not establish that every country offers the same functionality or that every desired number is immediately available.
KrispCall’s public pricing currently describes both included allowances and pay-as-you-go charging. Obtain written confirmation of the allowances applied to your account, eligible destinations, overage rates, number rental and messaging charges. Treat unlimited claims as route-specific and subject to fair-use terms, not unlimited worldwide service.
Best-fit scenario: A customer-facing team wants shared history, an eligible international number and demonstrated CRM or sequential dialing behavior. KrispCall belongs on that shortlist.
Main limitation to resolve: Advanced contact-center requirements such as complex queue reporting or workforce processes need a specific demonstration. Do not infer them from general “contact center” marketing.
Read our KrispCall review.
4. Dialpad: Comparing business calling with AI-assisted workflows
Dialpad is worth evaluating when calling and AI-assisted communication are central to your replacement decision. The important distinction is between Dialpad Connect for business communications, Dialpad Sell for sales workflows and Dialpad Support for customer support.
Why consider switching: Your team has a specific requirement for call transcription, follow-up information or a sales/support process that you want demonstrated in the working environment.
The trade-off: “Dialpad” is a brand, not one interchangeable subscription. A Connect quote should not be treated as a replacement for Zoom Contact Center operations without checking the relevant product. AI functions, integrations and management tools depend on the purchased package.
Test before buying: Run a normal customer call in your working language. Check the customer name, dates, commitments and next steps in the output, then show how staff correct mistakes and access the record.
May not suit: A team choosing on an AI headline alone. Accuracy, permissions, retention and the resulting staff workflow matter more than the number of AI features on a comparison page. Ask for pricing against the actual Connect, Sell or Support requirements.
Read our Dialpad review.
5. GoTo Connect: Office phone routing with meetings and messaging
GoTo Connect offers a cloud phone system alongside meetings and messaging. It is a relevant Zoom Phone alternative when business-hours routing, departments and distributed employees are the main buying priorities.
Why consider switching: Your team needs a phone system whose routing and administration fit the way incoming calls actually move through the business.
The trade-off: Phone System and contact-center offerings have different scope. Calling allowances also vary by region and number type; an international coverage headline is not a promise that every overseas destination is included.
Test before buying: Recreate your opening hours, holiday schedule, reception menu and unavailable-employee fallback. Check what happens when the primary employee’s mobile app is offline.
May not suit: A buyer who needs a precise low entry cost before discussing region, users and package. Obtain a quote that identifies international routes, toll-free allowances, required customer channels and any advanced reporting separately.
Read our GoTo Connect review.
6. Quo: Small teams sharing customer calls and texts
Quo, formerly OpenPhone, is a strong small-business option to evaluate when shared customer calling and texting are the priority. It is particularly relevant for an agency, contractor or service business whose employees coordinate around the same customer conversations.
Why consider switching: You want to compare a focused shared-phone workflow against a broader communications package, especially if many suite features are unused.
The trade-off: Quo’s number offering focuses on US and Canadian local numbers and North American toll-free numbers. It supports international calling to eligible destinations with usage charges, so number geography should not be confused with calling coverage.
Test before buying: Let two employees handle one customer conversation, transfer a call and complete the follow-up. Confirm the tier required for your menu, CRM and other workflow needs.
May not suit: A business requiring local numbers in several overseas markets or advanced contact-center management. Check those requirements before using the subscription price as the main reason to switch.
Read our Quo review.
7. Calilio: Phone-focused service with international number requirements
Calilio is another provider to evaluate when a business wants cloud calling and access to numbers in supported international markets. It offers an additional comparison for buyers whose decision centers on telephony rather than a broad collaboration suite.
Why consider switching: You want a second quote for the country, number and shared calling requirements that prompted the search, rather than relying on one international-number provider.
The trade-off: Subscription price, included allowances and metered usage are separate considerations. A country appearing in a coverage list does not prove that the desired number is available immediately or supports every messaging function.
Test before buying: Verify your number, inbound calls, outgoing caller ID and customer follow-up. Demonstrate any required recording, reporting or integration in the proposed tier.
May not suit: A direct replacement for advanced Zoom contact-center operations without a detailed capability check. Also confirm the plan’s user limit before estimating the subscription for a growing team.
Read our Calilio review.
8. CallHippo: For a Dedicated Sales-Calling Evaluation
CallHippo belongs on the shortlist when the requirement is a dedicated customer-calling or sales process. Its offering includes business phone and dialer capabilities, and its pricing page describes integration options for connecting calling with business software.
Why consider it: Representatives need a phone workflow tied to customer records rather than only external calls within a collaboration workspace. Compare how the proposed product handles calls, outcomes and follow-up.
The trade-off: Product scope and dialer capabilities are not established by the lowest entry headline. Confirm the exact package, dialing mode, integrations, seat conditions and usage charges. Number access does not prove that every number supports SMS or the desired caller ID.
Demo task: Work through a small representative list, record outcomes and inspect the resulting CRM activity. Test missed calls and another employee taking over the customer follow-up.
May not suit: A replacement for the full Zoom collaboration environment, or an advanced contact-center operation without a specific capability demonstration.
Compare Pricing Against Your Actual Calling Pattern
A lower seat price may produce a higher monthly bill when calls, numbers or essential tools are charged separately. Obtain quotes in the same currency, region and billing term.
Use this cost model: Required seats + additional numbers + chargeable calling and messaging + feature add-ons + applicable taxes and fees + transition costs. Record any minimum seats and annual commitment before comparing.
- Usage: Separate inbound, outbound, international and toll-free traffic. List the destinations that generate most minutes.
- Numbers: Include rental, porting conditions and additional departmental numbers.
- Tools: Include the dialer, CRM, recording, AI and supervisor capabilities employees actually need.
- Retained subscriptions: Zoom meetings may remain after replacing Zoom Phone. Count only the costs that genuinely disappear as savings.
- Contracts: Compare annual commitment, renewal and cancellation terms as well as the displayed monthly equivalent.
Illustrative example: Ten seats at $15 cost $150 before other charges. Ten seats at $12 cost $120. If the second quote adds $60 in required usage and features, it totals $180. These are illustrative numbers, not provider offers.
KrispCall’s displayed annual per-user monthly rates are $12 for Starter, $32 for Advance and $48 for Max. Its plan and user limits matter, and usage must be confirmed separately. These rates were checked October 2, 2026 and may change.
For other providers, request a quote for the required product rather than comparing a basic business-phone price with a sales or contact-center package. Ask for a sample invoice using your current traffic.
International Numbers and International Calling Are Different
Buying a local number abroad, calling a destination abroad and employing someone abroad are separate requirements. Verify each one for the proposed account.
Quo is a strong candidate for small teams needing US, Canadian or supported toll-free numbers and shared customer communication. Its number footprint does not mean it cannot call internationally: international calling uses destination-based charges and the applicable account setup.
KrispCall and Calilio are worth comparing when the requirement includes a local number in another supported market. Confirm live inventory, documentation, caller ID, inbound service and any messaging support. Do not infer SMS support from voice-number availability.
Zoom’s regional unlimited or Global Select terminology should not be read as unrestricted worldwide outbound calling. Compare the eligible local calling arrangement and separately priced international destinations.
Useful quote request: “We need one number in this country, these monthly inbound minutes, these outbound destinations and shared customer SMS where supported.” This is more precise than asking for a global phone plan.
Shared Customer SMS: Demonstrate Ownership and Follow-up
Internal team messaging and customer SMS are different workflows. A service can offer both without managing customer handover in the way your staff need.
Send a message to the proposed number, have one employee respond and ask another employee to continue the conversation. Check history visibility, unread status, notifications and how the team avoids duplicate replies. Demonstrate the eligible permissions rather than assuming every user sees every conversation.
Ask about registration, supported countries, number types, segment billing, attachments and retention. Test the actual number configuration. A demo message sent from an unrelated account proves little about the purchased setup.
If customer messaging is the central problem, prioritize that demonstration over meetings or internal chat features that already work well elsewhere.
Sales Dialers and Contact Centers Need Their Own Comparison
Specify the calling process before choosing a provider. Sequential power dialing, parallel dialing and predictive dialing handle lists differently. They are not interchangeable features.
Zoom has an Auto Dialer offering with its own license requirements. Establish whether that solves the sales requirement before concluding that a separate vendor is necessary. Compare it with the exact eligible KrispCall, Dialpad or CallHippo configuration.
For a support team, define queue behavior, agent availability, transfers, reporting and supervisor permissions. For more advanced operations, include workforce processes and channel requirements in the quote. Zoom Phone and Zoom Contact Center should not be treated as one identical subscription.
Our omnichannel contact-center guide helps define those requirements. A provider should demonstrate the same scenario in the proposed package.
When You Should Keep Zoom Phone
Keep Zoom Phone when employees benefit from its place in the Zoom environment, calling works well and the full bill fits the business. Moving can add training, integration work and another administration process.
If only one team needs a specialized tool, compare an eligible Zoom add-on or a focused solution for that group. A company-wide migration may be unnecessary. If the concern is a particular destination charge, compare real traffic rather than assuming all calls are expensive.
Retaining Zoom meetings while changing the phone service is also a possible outcome. Calculate both subscriptions and test how employees move between apps before deciding that the arrangement improves daily work.
The quick overview above includes both supplied Zoom offers so businesses that decide to stay can review the relevant route for their team size.
How to Evaluate Two or Three Finalists
Use the same short demonstration for each provider. Involve the receptionist, salesperson or support employee who will do the work.
- Receive a call from a known customer and locate the correct record.
- Transfer the call and show the receiving employee’s context.
- Leave a voicemail while the responsible person is unavailable.
- Send a customer follow-up through the required supported channel.
- Check the CRM activity, recording and access permissions.
- Run an after-hours call and an unavailable-device scenario.
- Inspect the report and explain the associated usage charge.
For AI output, check names, dates, commitments and numbers rather than just whether a summary appears. Establish how staff correct errors and who can access transcripts. Test typical headsets, employee devices and connections.
Call quality depends partly on network conditions and hardware. A demo on a salesperson’s connection does not establish performance in your office. Request a pilot where available and review the actual conditions before a larger rollout.
Switching From Zoom Phone: Migration Checklist
Number porting does not automatically move voicemail, recordings, routing, permissions or CRM history. Identify the records and configurations you need to retain.
- Inventory users, direct numbers, departmental numbers, devices and add-ons.
- Identify Zoom subscriptions and integrations that will remain.
- Review contract dates, cancellation conditions and any carrier involvement.
- Confirm portability by country and number type, plus required authorization.
- Export or retain necessary records and confirm import limitations.
- Rebuild menus, business hours, queues, delegation and fallback destinations.
- Verify device compatibility and applicable emergency-location setup.
- Complete necessary customer-messaging registration and integration checks.
- Verify inbound calls, outbound caller ID, transfers and voicemail after porting.
- Keep the old service active until the transfer and essential functions are confirmed.

Frequently Asked Questions
What Is the Best Zoom Phone Alternative?
RingCentral and Nextiva are relevant for wider communications, KrispCall for shared customer calling and supported international-number requirements, and Dialpad for AI-assisted or dedicated sales/support products. Choose according to the work and complete quote.
Which Alternative Is Best for a Small Business?
Quo is a strong option when shared calls and texts with US or Canadian numbers meet the need. KrispCall and Calilio add useful comparisons for other supported number markets. The appropriate plan, usage and team permissions still matter.
Can I Keep Zoom Meetings and Replace Zoom Phone?
Yes, that can be the chosen arrangement. Review your actual subscriptions and bundles, retain the required meeting entitlement and evaluate how employees will use the separate phone service.
Does Zoom Phone Include Unlimited International Calling?
Do not assume that. Metered and regional unlimited arrangements differ, and international destinations need their own rate and eligibility check.
Does Zoom Offer a Sales Dialer?
Zoom describes an Auto Dialer offering with separate licensing requirements. Compare its eligible configuration with the exact dialing mode your team needs.
Are Calilio and CallHippo Relevant Competitors?
Yes. Calilio is relevant to phone-focused and international-number evaluations, while CallHippo is relevant to dedicated sales and CRM/dialer requirements. Demonstrate the exact package rather than assuming either replaces all Zoom collaboration functions.
Can I Keep My Existing Zoom Phone Numbers?
Often, subject to country, number type, carrier and receiving-provider eligibility. Confirm portability and authorization before scheduling the move. Keep existing service active until transfer is verified.
Which Zoom Link Should a Team of 50 People Use?
The supplied routes are labeled 1–50 users and 50+ users. Since the labels overlap at 50, confirm the applicable offer rather than assuming a different price or entitlement.
Choose the Alternative That Improves the Work
Shortlist providers around the specific requirement that Zoom Phone currently does not satisfy. Compare the same calling scenarios, supported numbers and full costs. Keep Zoom Phone when its existing configuration or an eligible add-on remains the better fit.
RingCentral, Nextiva and KrispCall provide three useful starting points for different requirements. Dialpad, GoTo Connect, Quo, Calilio and CallHippo broaden the shortlist where their phone or customer workflows fit.
