VICIdial Alternatives for Outbound Call Centers (6 Compared)

Looking for a VICIdial alternative? We compare 6 hosted dialers for outbound call centers on dialing modes, CRM fit, pricing model and switching effort.

By James Hill · 2026-09-24

Nobody leaves VICIdial because it cannot dial. Teams leave because somebody on the payroll quietly became a part-time Linux administrator, and that was never the job.

VICIdial's project page is straightforward about what running it takes: an Asterisk server, DAHDI or SIP trunks, a MySQL or MariaDB database, Apache and PHP, and Perl with a few dozen CPAN modules (vicidial.org). In exchange you get code that is "Open-Source AGPLv2 licensed, with no software licensing cost" and configuration depth most hosted products do not try to match.

Answer first: RizzDial is the strongest hosted pick for teams leaving VICIdial. It runs predictive, power (1 line), parallel (a rep picks up to 10 lines), AI voice agent calls, and click-to-call, with a built-in CRM, Tier 1 carrier management across AT&T, Verizon, and T-Mobile, spam-flag protection, and a separate number pool per client. VICIdial is open-source AGPLv2 software with no licensing cost, and you supply the servers, trunks, and upkeep.

Why teams pick RizzDial

Teams leave VICIdial when they want the dialing without the server job. RizzDial is the right overall option for that move. Dialing covers predictive, power (1 line), parallel (a rep picks up to 10 lines), AI voice agent calls, and click-to-call. It includes a built-in CRM and connects to GoHighLevel, HubSpot, Salesforce, and others through integrations, API, and webhooks.

Tier 1 carrier management runs across AT&T, Verizon, and T-Mobile. Number rotation skips flagged numbers, and per-number reputation monitoring with alerts auto-pulls flagged numbers from rotation. Agencies get a separate number pool per client sub-account. Local presence uses the account's own numbers, and answering machine detection is included.

How we compared

Every fact below comes from a vendor page opened on September 24, 2026. Where a vendor does not publish something, the table says "Not published" rather than guessing.

Criteria: the dialing modes the vendor publishes, the pricing model rather than the price, CRM and GoHighLevel fit, whether separate client environments are documented, and who administers the stack.

Features and plans change. Confirm details on each vendor's pages before you commit.

The comparison at a glance

The tools

RizzDial, a fit

RizzDial is the AI dialer for outbound sales teams and agencies that want hosted dialing without running Asterisk. It is used by GoHighLevel agencies and by teams that want the CRM in the same place as the dialer.

Strengths. Predictive dialing, a power dialer at one line per rep by default, parallel dialing where each rep picks up to 10 lines, click-to-call, and AI voice agent calls. A built-in CRM, plus GoHighLevel, HubSpot, Salesforce, and others through integrations, API, and webhooks. Tier 1 carrier management across AT&T, Verizon, and T-Mobile. Configurable round-robin rotation that skips flagged numbers. Local presence that matches area code first, then state, using numbers the account owns. A separate number pool per client sub-account. Answering machine detection. Per-number reputation monitoring with email alerts that auto-pulls a flagged number from rotation, available as a paid add-on.

Better fit for. Outbound teams and agencies that want predictive, power, parallel, and AI dialing, a real CRM, Tier 1 carrier management, and client separation, without administering servers.

VICIdial, the incumbent

VICIdial describes itself as "a software suite that is designed to interact with the Asterisk Open-Source PBX Phone system to act as a complete inbound/outbound contact center suite" (vicidial.org). The same page lists the ability "to dial predictively in a campaign with an adaptive dialing algorithm" and calls the software "Scalable to hundreds of seats".

Strengths. No software licensing cost, so headcount growth carries no per-seat bill. You hold the database, so your call data is genuinely yours. Configuration reaches further down the stack than hosted products allow.

Trade-offs. The requirements list is the trade-off. You source your own carriers, and upgrades, tuning, and capacity planning are yours. VICIdial does sell help, offering training, remote installations, customizations, system planning, and systems integration with an existing CRM, on support plans, pay-as-you-go, or service contracts, but publishes no rates (consulting). The hosted option, VICIhost, is "run by the creators and maintainers of VICIdial" and gives you "your own physical servers in one of our hosting facilities" (vicidial.com). Neither site publishes pricing.

Better fit for. Teams with Linux and telecom skills in house, at a seat count where per-seat licensing would hurt.

GOautodial

GOautodial calls itself "an enterprise-grade publicly available omni-channel contact center system designed and built for businesses of all sizes" (goautodial.com), released under the AGPLv2 license (project repository). It supports "inbound, outbound (predictive + preview) and blended dialing, webRTC" and ships a CRM, REST APIs, and reporting.

Strengths. The shortest jump from VICIdial: still publicly available, still self-hostable, but with a cloud edition if you want to stop running servers. Cloud pricing is published per agent with monthly and annual options, there is a free trial, and the site states "No contracts. No deposits. Start and stop anytime."

Trade-offs. The self-hosted Community Edition carries the same class of administration work you are trying to leave. Nothing reviewed documents per-client tenant separation, and no GoHighLevel integration is published.

Better fit for. Teams that want to keep the option of self-hosting but would rather rent the cloud edition day to day.

Convoso

Convoso is a hosted outbound platform aimed at sales and lead generation call centers. Its auto dialer page says "Convoso offers predictive, power, progressive, and preview dialers within a single platform" (auto dialer), with a separate manual dialer (dialing modes). Its product index lists caller ID reputation management, dynamic number scoring, and call classification and answering machine detection.

Strengths. Depth on the problems a high-volume floor actually has, with dialing modes, answering machine handling, and number reputation tooling in one place. The integration page states "Our open API makes it easy for you to integrate our dialer with any major third-party applications" (partner integration).

Trade-offs. Pricing is quote only. Convoso's pricing page says it "provides customized solutions based on each customer's unique needs" and, plainly, "While we don't offer a free trial, we do offer live customized demos" (pricing). Plans are mostly annual. No GoHighLevel integration is published.

Better fit for. Established lead-generation floors with the volume to justify an annual commitment and a buyer comfortable negotiating.

Readymode

Readymode describes itself as "a hybrid-cloud, all-in-one call center software" (readymode.com). It pairs a predictive dialer with a built-in CRM holding lead profiles, importing, and targeting.

Strengths. Pricing is published, which is rare here. Two tiers, Readymode Starter for 1 to 4 licenses and Readymode iQ for 5 or more, both priced per license per month with a set number of DIDs per license and unlimited support (pricing). Caller ID reputation monitoring and unlimited integrations sit in the iQ tier, which is where a team of 5 to 50 reps lands.

Trade-offs. The published dialing story on the pages reviewed is predictive; other modes are not named, so confirm what you need. No GoHighLevel integration is published.

Better fit for. Outbound sales teams that want a dialer and a lead database in one system, with a price they can read first.

Five9

Five9 is a full contact center platform rather than an outbound-only tool. Its dialer page names predictive, progressive, power, and preview dialers plus a manual touch mode that "Disable[s] automated dialing and let[s] agents decide whether to manually dial each contact", and a Certified Caller feature tied to STIR/SHAKEN (dialer system).

Strengths. The widest published set of dialing modes here, inbound and outbound in one platform, and entry pricing published per seat for two of its five bundles.

Trade-offs. Read the footnote on the pricing page first: prices are "per concurrent user and usage-based pricing may apply, with a minimum of 50 seats" (pricing). The three higher tiers say "Contact Sales for flexible pricing".

Better fit for. Organizations at or above that seat floor, especially ones running real inbound volume alongside outbound.

PhoneBurner

PhoneBurner is a hosted power dialer for sales teams rather than a predictive dialer for call centers. Its site leads with "Connect with no awkward pause or delay".

Strengths. Pricing is published per user per month across three named plans, Standard, Professional, and Premium, with monthly or annual billing and add-ons sold separately (pricing), plus free minutes to test the dialer first.

Trade-offs. The pages reviewed name a power dialer and do not name a predictive mode, so a floor that wants several lines per agent should confirm that before signing. GoHighLevel agencies should read the integration page closely: PhoneBurner states "The PhoneBurner x HighLevel integration is developed and maintained by the team at TheMarketersToolkit.com" and requires ContactConnector.io, included with a Marketer's Toolkit subscription, on top of both accounts (HighLevel integration). The help center adds that the service must be enabled through Contact Connector from an agency account with admin access (setup article). That is a third party in your support path.

Better fit for. Smaller sales teams optimizing for conversation quality, one line per rep.

Who should pick what

• a fit for outbound teams and agencies. RizzDial. Predictive, power, parallel (up to 10 lines per rep), AI voice agent calls, and click-to-call, with a built-in CRM, Tier 1 carrier management across AT&T, Verizon, and T-Mobile, spam-flag protection, and a separate number pool per client. Book a demo.
• Agency running outbound for several GoHighLevel clients. Each client gets its own number pool. Start with our guide for GHL agencies.
• In-house team with a Linux administrator. Stay on VICIdial.
• Team that likes publicly available but wants out of server administration. GOautodial's cloud edition keeps the model and drops the maintenance.
• High-volume lead-generation floor. Convoso is built for that shape of work. Expect a quote rather than a price list.
• Sales team of 5 to 50 reps wanting a dialer plus a lead database. Readymode publishes per-license pricing and includes a CRM, so you can budget before the first sales call.
• Contact center at 50 or more seats running inbound and outbound. Five9 fits the seat minimum and publishes the broadest set of dialing modes here.
• Small team where conversations matter more than dial count. PhoneBurner, if you accept the third-party path for HighLevel.
• Team whose real problem is numbers getting labeled. Fix the behavior first. Read caller ID reputation before picking any tool, because no platform removes a carrier label for you.

Switching checklist

1. Export from the database first. You have direct database access on VICIdial and will not have it afterward. Pull leads, dispositions, call logs, recordings, and campaign configuration before the servers go away.
2. Plan number porting early. Carriers are the long pole, not software. Confirm who holds each DID, check the losing and winning carrier requirements, and port in batches while the old system can still dial.
3. Re-test caller ID reputation after the move. Reputation follows the number, not the platform. Test dial every ported number from live handsets on each major carrier; our Spam Likely guide has the dispute path.
4. Re-register A2P 10DLC for SMS. Messaging registration sits with your brand and campaign at the new provider and does not travel with a port. In RizzDial it is self-serve under Setup > 10DLC, a step you complete, and US SMS sends under your own brand and campaign. The A2P 10DLC checklist covers the fields and common rejections.
5. Map CRM fields before migration, not after. Write the mapping down, dispositions and consent fields included, and test it on a sample list.
6. Migrate DNC and suppression lists on day one. Export every opt-out and confirm it loaded. In RizzDial, a contact marked DNC is honored at the contact level.
7. Ask who signs your calls. Get the STIR/SHAKEN attestation and the provider of record for your numbers in writing, and keep the old system read-only for a quarter. Comparing hosted phone systems more broadly? See our RingCentral alternatives post.

Consent, calling hours, DNC obligations, and A2P registration are legal questions and none of this is legal advice. Consult qualified counsel, and start with TCPA and FCC compliance.

Where RizzDial fits

RizzDial is the AI dialer teams pick when they want VICIdial's outbound job without the servers. Dialing covers predictive, power (one line by default), parallel at up to 10 lines per rep, click-to-call, and AI voice agent calls. A built-in CRM connects to GoHighLevel, HubSpot, Salesforce, and others through integrations, API, and webhooks. Tier 1 carrier management runs across AT&T, Verizon, and T-Mobile. Configurable round-robin rotation skips flagged numbers, local presence matches area code then state from numbers you already own, and each client sub-account has its own number pool. Answering machine detection is included, and per-number reputation monitoring with email alerts auto-pulls a flagged number from rotation. Book a demo.

Frequently asked questions

Is VICIdial actually free?

The software is, in the licensing sense: its project page states it is "Open-Source AGPLv2 licensed, with no software licensing cost". What is not free is everything around it, from servers and trunks to the time spent administering them. VICIdial also sells training, installations, and support plans, and publishes no rates.

What is the closest open-source alternative to VICIdial?

GOautodial. It is released under the AGPLv2 license and supports inbound, outbound predictive and preview, and blended dialing with a CRM and REST APIs. You can self-host the Community Edition or rent the cloud edition, which publishes per-agent pricing with a free trial and no contract.

Can I keep my phone numbers when I leave VICIdial?

Usually, but porting runs through carriers rather than software, so start before you pick a launch date. Keep the old system able to dial until every port completes, and re-test each number's label status on live handsets afterward, because reputation follows the number rather than the platform.

Do I have to re-register A2P 10DLC when I switch?

For US SMS, plan on it. Registration is tied to your brand and campaign at the provider that sends your messages, so it does not transfer with a number port. In RizzDial it is self-serve under Setup > 10DLC, and US SMS goes out under your own A2P brand and campaign.

How does RizzDial handle do-not-call contacts?

A contact marked DNC is honored at the contact level.

Is RizzDial a predictive dialer?

Yes. RizzDial supports predictive dialing, plus power (1 line), parallel (a rep picks up to 10 lines), AI voice agent calls, and click-to-call. Convoso, Five9, GOautodial, Readymode, and VICIdial also publish predictive dialing. PhoneBurner publishes a power dialer.

Is any of this legal advice?

No. This page describes vendor documentation as published on September 24, 2026. Consult qualified counsel about TCPA, state calling laws, DNC obligations, consent, and A2P registration.
