A VoIP dialer is software that places phone calls over the internet instead of a copper line, usually from a browser or desktop app, with the dialing, logging and recording handled for the rep. The differences between dialers come down to how they choose the next number to call, how clean the audio is, and whether your caller ID still gets answered after a few thousand calls.
This guide covers each of those, plus the compliance basics, the per-minute math, and where the Ready Dialer fits. It also covers where it doesn't fit. If you need a dialer that calls several numbers at once and hands live answers to reps, the Ready Dialer is not that product, and we explain why below.
What a VoIP dialer actually is
A desk phone has a line. A VoIP dialer has an account. The "phone" is a softphone in your browser or app, the numbers belong to your provider account, and every call is a data stream that ends up on the public phone network at the far end.
That brings three practical changes for a sales team:
- Numbers are software objects. You can buy a local number in a new area code in minutes and assign it to a rep or a market, with no hardware involved.
- Every call is data. Duration, outcome, recording and transcript can attach to the contact record automatically, so reps don't type up call notes from memory.
- Calling sits next to everything else. The dial pad can live inside your CRM, next to the contact's text history and pipeline stage.
How internet calling differs from a desk phone
A traditional line reserves a dedicated circuit for the length of the call. VoIP breaks your voice into small packets, sends them over your internet connection, and reassembles them at a gateway that hands the call to the carrier network. That design causes most of the good and the bad.
| Desk phone (PSTN line) | VoIP dialer | |
|---|---|---|
| Where it runs | Physical handset on a line | Browser, desktop app or mobile app |
| Adding a number | Order from the phone company, wait | Buy in minutes, assign in software |
| Audio quality depends on | The line | Your network: bandwidth, latency, jitter, packet loss |
| Call logging | Manual | Automatic, attached to the contact |
| Recording and transcripts | Extra hardware or service | Usually built in, with consent handling |
| Works when the internet is down | Yes | No |
That last row is a real tradeoff. A team running entirely on VoIP needs a backup connection (a second ISP or a mobile hotspot) if calling is how it makes money.
Manual, preview, progressive and predictive dialing
The dialing mode decides who picks the next number and how many calls are in flight per rep. This is the biggest functional difference between products, and it also changes your legal exposure.
| Mode | How it works | Calls in flight per rep | Best for |
|---|---|---|---|
| Manual (click-to-call) | Rep clicks a number, the dialer places the call | 1 | Inbound leads, follow-ups, high-value accounts |
| Preview | Dialer queues the next contact and shows the record; rep reviews, then dials | 1 | Complex B2B calls where context matters |
| Progressive | Dialer places the next call automatically as soon as the rep is free | 1 | Medium-volume outbound with a clean list |
| Predictive | Dialer calls several numbers at once and connects answered calls to free reps | Several | High-volume outbound with many reps |
The tradeoff in plain terms
Predictive dialing produces the most talk time per hour on a big list. It also produces dropped calls: when two people answer and only one rep is free, someone hears silence or a hang-up. The FTC's Telemarketing Sales Rule caps abandoned telemarketing calls at 3% per campaign over a 30-day period, and it requires connecting an answered call to a live rep within two seconds of the greeting. Automated dialing to cell phones also raises consent questions under the TCPA. If you run predictive, your provider and your counsel both need to be involved.
Manual and preview dialing are slower. Every call is one a rep chose to make, which keeps abandonment at zero and makes conversations warmer. For teams working inbound leads, where speed to the first touch matters more than raw dials per hour, manual is usually the right mode anyway.
Call quality: what actually causes bad calls
Most "the dialer sounds bad" complaints are network problems, not software problems. Four things to check before blaming the vendor:
- Bandwidth. A single uncompressed voice call uses roughly 100 kbps in each direction. That's small, but a rep on hotel Wi-Fi sharing it with a video upload will hear it.
- Latency. Above roughly 150 ms one-way, people start talking over each other. Wired Ethernet beats Wi-Fi almost every time.
- Jitter. Packets arriving unevenly cause choppy, robotic audio. Business-grade routers with quality-of-service settings help.
- The headset. A USB headset with a noise-cancelling mic does more for perceived quality than any codec setting.
When you evaluate a VoIP dialer, make 20 test calls from the actual desks your reps use, at the time of day they call. A demo from the vendor's office tells you nothing.
Caller ID reputation and spam labels
You can have perfect audio and still get no answers if the recipient's phone shows "Spam Likely." Carriers and their analytics partners score calling numbers on behavior. Large daily volume from one number, very short average call length and lots of declined or unanswered calls all push a number toward a spam label.
What helps:
- Signed calls. STIR/SHAKEN attestation tells the receiving carrier the caller is authorized to use the number. Ask any provider what attestation level your outbound calls get.
- Volume per number. Spread outbound across several numbers rather than burning one.
- Local numbers. People answer a familiar area code more readily than an unknown toll-free number. That's the usual reason teams buy numbers per market.
- Registering your numbers with the carrier analytics registries, and branded caller ID where it's available. Our branded caller ID explainer covers how that works.
- Not calling bad data. Disconnected and wrong numbers drag your answer rate down, and a low answer rate drags your reputation down with it.
Compliance basics before the first dial
This is not legal advice, and the sender is responsible for compliance. Here is the minimum a sales team should have in place:
- Calling hours. Telemarketing calls are limited to 8 AM to 9 PM in the recipient's local time under federal rules. Some states are stricter.
- The National Do Not Call Registry. Telemarketing calls to registered numbers need an exemption, such as an established business relationship or written permission. Check the list before a campaign and refresh it on the schedule the rules require.
- Internal do-not-call list. If someone asks you to stop calling, record it and honor it across every rep and number.
- Consent for automated or prerecorded calls. Manual click-to-call is the lowest-risk mode. Anything automated to cell phones needs a consent review.
- Recording consent. Some states require all parties to agree to recording. Our post on call recording consent laws walks through the one-party vs all-party split.
Ready's standalone TCPA & DNC Litigator Scrub costs $0.005 per contact. It checks each number against known TCPA-litigator lists and DNC-complainer lists and flags matches. TCPA damages run $500 to $1,500 per violation, so screening a 2,000-contact list (2,000 × $0.005 = $10) is cheap insurance. It reduces risk. It does not make you lawsuit-proof, and it doesn't replace your own registry and internal-list process.
Pairing calls with texts: the Ready Dialer
We make Ready, so here is exactly what the Ready Dialer does and doesn't do.
What it does:
- Click-to-call from the dial pad in the Ready dashboard or inside GoHighLevel.
- Calls from the same numbers your account already texts from.
- Consented call recording and transcripts.
- Inbound calls that ring the open pad.
- A Missed call card in the Inbox thread for each missed call.
What it doesn't do: queue or automatic dialing, progressive or predictive modes, auto-dial on new leads, voicemail drop, transfers, or manager monitoring (barge and whisper). If your team lives on predictive dialing across a large outbound list, a dedicated contact-center dialer is the right tool, and you should buy one. Our real estate wholesaling dialer comparison covers that kind of workflow.
Pricing: $0.025/min, with each started minute billed as a full minute. There are no seat plans, and every minute is billed from the first one. A call that's never answered isn't billed.
The first-five-minutes pattern
The Ready Dialer fits teams working inbound and opted-in leads. A typical pattern looks like this:
- A lead submits a form with SMS consent.
- An automation sends an instant text right away.
- A rep calls by hand from the pad within minutes, from a number the lead has just seen in their text thread.
Texts go out on your registered 10DLC campaign. If you're new to that, read what 10DLC is. With Local presence on, Ready texts from your number closest to the contact's area code. Local presence has a listed price of $0.0015 for each segment of a delivered text.
Worked example: cost per connect
Assumptions: one rep, 80 manual dials a day: 30 ring out unanswered, 30 reach voicemail and hang up in under a minute, and 20 connect for 4.2 minutes on average.
- Unanswered calls: 30 calls, free, because Ready bills connected time only.
- Voicemail: 30 calls × 1 billed minute = 30 minutes.
- Connects: 20 calls, each billed at 5 minutes because started minutes round up, = 100 minutes.
- Calling cost: 130 minutes × $0.025 = $3.25 a day.
- Cost per connect: 130 minutes over 20 connects is 6.5 minutes each, so 6.5 minutes × $0.025 = $0.16.
Add the instant text to each of the 80 leads. At one segment each, that's 80 × ($0.0075 + $0.0045). Ready bills texting at one Standard rate of $0.0075/segment plus the $0.0045 carrier fee.
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.
Two levers matter more than the per-minute rate. The first is connect rate, which comes from list quality and caller ID reputation. The second is short calls: a 61-second call bills as two minutes.
What to look for, and the practical takeaway
When you compare VoIP dialers, check these:
- Dialing modes that match your motion: manual or preview for inbound, predictive only if you have the reps and the compliance process for it.
- Billing increments. Per-second, per-6-second and per-minute rounding change your real cost on short calls.
- Caller ID tools: STIR/SHAKEN attestation, local numbers and number rotation.
- Recording with consent handling, plus transcripts.
- Calls and texts in one place, from the same numbers, attached to the same contact.
- Network requirements you can actually meet at your reps' desks.
The practical takeaway is to pick the dialing mode first, then the vendor. If your leads come in warm and you text them before you call, a click-to-call dialer sitting next to your texting is often all you need.
When you're ready to try it, create an account. Your first 20 one-to-one texts are free, and to send any text you need a card and a number ($2 a month, the first month charged when you get it).
FAQ
Is a VoIP dialer legal for cold calling?
Calling itself is legal, but telemarketing calls must respect calling hours, the National Do Not Call Registry and your internal do-not-call list. Automated or prerecorded calls to cell phones need consent. Texting is different: send texts only to people who opted in or replied to you.
Do I need special hardware?
No. A computer, a USB headset and a stable wired internet connection are enough. A backup connection is worth having if calling drives your revenue.
Why do my calls show as "Spam Likely"?
Usually it's high volume from one number, many short or unanswered calls, or calling bad data. Spread calls across local numbers, clean your list, and ask your provider about call signing (STIR/SHAKEN attestation).
Does the Ready Dialer do predictive or automatic dialing?
No. It's manual click-to-call from the dial pad in the dashboard or GoHighLevel, with recording, transcripts, inbound calls and a Missed call card in the Inbox thread for each missed call. Teams that need predictive dialing should use a dedicated contact-center dialer.
How is the Ready Dialer billed?
At $0.025/min, with each started minute billed as a full minute. There are no seat plans, and every minute is billed at that same rate from the first one, and a call that's never answered isn't billed. Texts are billed separately at the Standard rate of $0.0075/segment plus the $0.0045 carrier fee.
