Power dialers compared: Wavv, Vonage, ZoomInfo, Zoho and Yeastar, and where Ready fits

Most shortlists of power dialers blend products that do very different jobs. Some are standalone dialers built for one CRM. Some are dialing modules inside a phone system. Some come bundled with a contact data subscription. Comparing them on a feature grid without sorting them by type first is how teams sign a contract for the wrong tool.

This post sorts the seven names that keep showing up on sales managers' lists: Wavv, Vonage, VoipTools, ZoomInfo, Zoho, Yeastar and Ready. We make Ready, and Ready Dialer does not do power dialing. It is click-to-call with recording, transcripts and a Missed call card in the Inbox thread for each missed call, and it has no queue or auto dialing. If automatic list dialing is a hard requirement, one of the other six is your answer, and we say which below. Ready earns a place on the list for the text and manual-call work that happens around the dialer.

First, decide what kind of dialing you actually need

"Power dialing" is a term that gets used loosely. Before you compare vendors, pin down the mode:

• Click-to-call: the rep picks the next contact and clicks. There is no automation and no dropped calls. This works when each call needs prep, as with warm leads, callbacks and account managers.
• Power (progressive) dialing: the dialer calls the next number on the list when the rep finishes the last call, one line at a time. This suits high-volume outbound where the rep still needs to be present for every connect.
• Parallel or multi-line dialing: the dialer rings several numbers at once and hands the first answer to the rep. Reps get through more dials per hour, with more abandoned-call risk.
• Predictive dialing: an algorithm paces calls across a team based on answer rates. This is a contact-center tool, and its compliance exposure is highest.

We cover the tradeoffs in detail in power vs parallel vs predictive dialer. The short version is that more automation brings more dials per hour, more compliance work and usually a bigger contract.

The shortlist at a glance

We've left out vendor prices on purpose. Dialer pricing changes often, sits behind sales calls for several of these vendors, and depends on seat count and add-ons. Compare the pricing model, then get current quotes.

The standalone dialers: Wavv

Wavv is what many people mean when they talk about power dialers. It is a purpose-built outbound tool that sits on top of a CRM, with single-line and multi-line modes. It is popular with GoHighLevel agencies and small sales teams because it runs inside the CRM screen the reps already use.

Pick it when: outbound calling is the main activity, reps live in a CRM that Wavv supports, and you want multi-line dialing without moving to a contact center platform.

Watch for: per-user pricing climbs quickly as the team grows. Multi-line dialing also raises abandoned-call risk, so read how the tool handles a second answer before you turn it on. If you're on GoHighLevel and evaluating several options, power dialing options for GoHighLevel agencies beyond Aloware covers those options specifically.

The phone systems: Vonage and Yeastar

Vonage and Yeastar start from the phone system and add outbound dialing on top. That is the right order if you need a business phone system anyway, with extensions, IVR, ring groups and desk phones.

Vonage

Vonage sells both a business phone product and a contact center product, and the dialing capability differs a lot between them. The automated outbound modes and the deeper CRM integrations (Salesforce especially) live on the contact center side. Ask which product the dialer quote is for. A cheap business phone seat and a contact center seat are not the same purchase.

Pick it when: you're replacing the company phone system and want outbound dialing from the same vendor, or you run a Salesforce-centric team that wants telephony inside Salesforce.

Yeastar

Yeastar is a PBX vendor that offers cloud and on-premise systems and a contact center add-on. It appeals to companies that want to own their phone infrastructure or that already run Yeastar hardware. Outbound dialing capability depends on the edition and add-ons, so confirm the exact mode in a demo instead of assuming "contact center" means progressive dialing.

Pick it when: IT wants a PBX you control and outbound sales is one department among several on the system.

VoipTools

VoipTools comes up on fewer lists, and public detail on its dialing modes and CRM integrations is thinner than for the others. Treat it as a "verify everything" vendor. Ask for a live demo of the exact dialing mode, the CRM write-back (call logs, recordings, dispositions) and the contract terms before you shortlist it.

The data-plus-dialer bundles: ZoomInfo

ZoomInfo's dialer sits inside its sales engagement product, next to the contact data most teams buy ZoomInfo for. The appeal is that reps find a contact, get a direct dial and call from the same screen, with activity syncing back to Salesforce or HubSpot.

Pick it when: you're already buying ZoomInfo data and the dialer is a near-free add to an existing contract, or your SDR motion depends on its contact data.

Watch for: these are annual, sales-led contracts. If you only want a dialer, buying a data platform to get one is the expensive route.

The CRM-native option: Zoho

If your team runs on Zoho CRM, start with Zoho's own telephony (Zoho Voice) and its PhoneBridge integrations before you look anywhere else. Native call logging, click-to-call from records and a single vendor relationship are real advantages. Dialing modes depend on which telephony setup you use, so confirm that list-based dialing is available on your plan.

Where Ready fits, honestly

Ready is a texting platform and messaging API with calling built in. Here is what Ready Dialer does today:

• Click-to-call from the dial pad in the Ready dashboard or inside GoHighLevel
• Consented call recording and transcripts
• Inbound calls that ring the open pad
• A Missed call card in the Inbox thread for each missed call
• Per-minute billing at $0.025/min, with each started minute billed as a full minute. There are no seat plans, every answered minute bills at that one rate, and only answered time is billed.

Here is what it does not do: queue or auto dialing, multi-line dialing, voicemail drop, transfers, or manager monitoring (barge and whisper). If your reps need the dialer to move through a list on its own, Ready isn't your dialer.

Ready is strongest in the lane next to the dialer, which is texting consented leads and calling the hot ones by hand. The first few minutes after a lead comes in matter. Text arrives instantly, and a rep can follow up with a manual call from the same thread. Texts go out over registered 10DLC routes, and we handle registration in-app. Most approvals take 2 to 7 days. The compliance stack covers automatic STOP handling, quiet-hours holds based on the recipient's area, and optional litigator and DNC scrubbing.

Worked example: a rep's calling and texting day

Here is an example with stated assumptions, not a measured benchmark:

• A rep works 80 warm leads (inbound form fills and callbacks) by hand from the pad in a day.
• Assume a 15% answer rate, which gives 12 answered calls. The 68 that ring out or hit a busy line cost nothing.
• Assume answered calls average 4 billed minutes, which is 48 minutes × $0.025 = $1.20 in calling.
• The rep sends 40 one-segment follow-up texts to leads who opted in. That is 40 × ($0.0075 + $0.0045), so 40 segments at the Standard rate plus 40 carrier fees. Replies are billed the same way.

Ready's all-in prices per segment include the carrier fee but not screening: Scrub lists and Number validation, the two switches in Settings under Compliance, each add $0.003 per segment when switched on, shown as screening on your bill, and both are off by default. Unless you turn the opt-out footer off, the first text to each contact, and one again from time to time, also gets "Reply STOP to opt out" and your business name if the message does not already have them, so a text close to the segment limit can bill one more segment.

A day of manual calling plus follow-up texting comes to a few dollars, with no seat fee. For a high-volume cold calling floor, that math doesn't apply, because you'd want one of the automated dialers above. Ready Dialer is built for the warm-lead workflow, not as a replacement for power dialing.

If you dial cold lists

Cold outreach belongs on the phone and in the mail, not in a text. Scrubbing the list before anyone dials is cheap risk reduction. Ready's standalone TCPA and DNC litigator scrub costs $0.005 per contact and checks each number against known TCPA-litigator and DNC-complainer lists, flagging matches. Measured against TCPA exposure of $500 to $1,500 per violation, that's easy to justify. It reduces risk without making you lawsuit-proof, and compliance stays the caller's responsibility. Texting starts once a lead has replied or opted in.

How to pick: a five-question filter

1. Which dialing mode do your reps actually need? If click-to-call covers it, skip the expensive contracts. If you need list automation, look at Wavv, Zoho's telephony or a contact center tier.
2. Where do reps spend their day? Pick the dialer that writes back to that CRM natively. Integrations that look good in a demo can break in month two.
3. Do you need a phone system too? If yes, Vonage or Yeastar can consolidate the two purchases. If no, don't buy one to get a dialer.
4. Are you already paying for contact data? If ZoomInfo is in the budget, check its dialer before adding another vendor.
5. How will you handle texting? Most outbound teams text as much as they call. Decide whether texting lives in the dialer, the CRM or a dedicated platform with 10DLC registration and opt-out handling built in.

Run every shortlisted vendor through a one-week pilot with two reps on real leads, and compare connects, call-log accuracy and how often reps work around the tool.

The practical takeaway

Sort the list by type before you compare features. Wavv is a dedicated dialer. Vonage and Yeastar are phone systems with dialing options. ZoomInfo bundles a dialer with data. Zoho is the default if you already run Zoho CRM. VoipTools needs a careful demo. Ready is the call-and-text layer for warm leads, with click-to-call at $0.025/min and a compliance-first texting stack, and it doesn't automate list dialing.

If that workflow matches how your team sells, you can create an account. A card on file is required to send, and your first 20 one-to-one texts are free. Use them to test the inbox and calling flow before you pay for registration. Pricing details are on the pricing page.
