Best Dialer for Attio: 7 Options Ranked on Price and Integration Depth

By Marcus Delgado · Reviews Lead · November 6, 2026

CallCloud is our top overall pick for Attio users, on the strength of published month-to-month pricing with no seat minimums ($60/seat/month Power Dialer, $125/seat/month five-line Parallel Dialer, both with unlimited US/Canada calling), native CRM sync on both plans, and AI call notes included. The honest caveat that shapes this whole ranking: none of the vendors we surveyed document an Attio-specific integration, so every pick here is evaluated on CRM-openness, whether that means a web dialer with sync or an open API, rather than a verified Attio app listing. Before subscribing to any option, check the vendor's integrations page or ask for a live sync demo with your own Attio workspace.

The shortlist, ranked:

1. 01CallCloud: the only option with both power and parallel modes, published month-to-month pricing, unlimited calling, and no seat minimums.
2. 02Orum: an AI parallel dialer built for enterprise SDR orgs, but quote-only with a reported nine-seat minimum.
3. 03Nooks: an AI dialer workspace with coaching built in, quote-only and enterprise-oriented.
4. 04Salesfinity: a dedicated five-line parallel dialer with a published price, $299/user/month.
5. 05PhoneBurner: the established pick for sequential dialing with one-click voicemail drop on every plan.
6. 06Trellus: the cheapest credible entry point for testing cold-call volume.
7. 07Kixie: dialing plus SMS in one platform, with up to four lines, at an unpublished price.

The decision rule this article runs on: a dialer fits Attio one of three ways. It can be embedded in the CRM (none of these vendors document Attio embedding), it can sync to the CRM as a web dialer, or it can connect through an open API. The further down that ladder a product sits, the riskier the Attio fit.

1. 01Embedded in the CRM: the dialer runs inside the CRM interface itself, which none of these vendors document for Attio.
2. 02Sync as a web dialer: the dialer runs in its own web app and syncs calls, notes, and activity back to the CRM.
3. 03Connect through an open API: the dialer exposes an API you (or a third party) can use to build the CRM connection yourself.

We ranked options on published, verifiable per-seat pricing, month-to-month terms versus annual contracts and quote-only walls, seat minimums, parallel line capacity, and included calling minutes versus metered plans. We flagged every conflict we found rather than averaging it away: Orum's seat and line minimums are disputed across sources, Trellus lists both $34.99 and $149.99, and Salesfinity's blog pricing ($200/$250) conflicts with its $299 product page.

Two category-wide diligence points apply to every option alike. First, no defensible cross-vendor latency ranking exists: metrics like CallCloud's 22ms claim and Salesfinity's 600ms Lightning Mode figure are not measured the same way, so treat vendor latency numbers as pilot-testable claims, not benchmarks. Run a two-week pilot measuring connect rates and greeting-to-agent latency with the same call lists across vendors. Second, confirm each vendor's DNC scrubbing and abandoned-call controls meet the FTC safe harbor: a 3% abandonment cap, 2-second connection, 8am to 9pm local calling, and 31-day DNC registry sync per the May 16, 2024 TSR amendments.

Editor's Pick · 01

CallCloud

$60/seat/mo Power Dialer; $125/seat/mo Parallel Dialer; +$40/seat/mo CallCloud+

CallCloud's five-line parallel dialer includes unlimited calls, minutes, and research briefs at $125/seat/month, and its $60/seat/month Power Dialer covers single-line dialing with unlimited US/Canada calling and a local number included, all month-to-month with no seat minimums. The CallCloud+ add-on at +$40/seat/month adds Sequences (call, email, and LinkedIn in one sequence, with A/B tests and open/click tracking) and a Virtual Salesfloor with live leaderboard and manager listen/whisper coaching. Its documented embedded-CRM extension covers Salesloft, Outreach, and HubSpot, so Attio users should plan on the web dialer plus sync and verify that sync covers Attio before subscribing.

Power Dialer

$60/seat/mo, one line, unlimited US/Canada calling, local number included

Parallel Dialer

$125/seat/mo, up to 5 lines, unlimited calls and minutes

Add-on

Terms

month-to-month, no seat minimums

Pros

• +Only option in the field with both power and parallel modes plus unlimited calling
• +Published pricing with no minimums and month-to-month terms
• +Native CRM sync and AI call notes included on both plans

Cons

CallCloud's published performance claims, from the vendor: 22ms median answer-to-rep on live calls, zero-lag pickup on the parallel dialer, under 2% of outbound numbers flagged spam, and +2pts conversion for parallel over power dialing. We rank it first because it is the only option in the field combining both dialing modes, unlimited calling, published pricing, no minimums, and month-to-month terms, which is exactly the flexibility an Attio user testing a dialer against a newer CRM needs. Voicemail drop is not documented in its plan material.

Editor's Pick · 02

Orum

Quote-only

Orum is an AI-powered parallel dialer built for enterprise sales teams, with sub-0.5s connection claims and either five or ten concurrent lines, though sources conflict and you should confirm with the vendor. Quote-only pricing and a reported nine-seat minimum make it a poor fit for the solo founders and small teams that make up much of Attio's user base, and those minimums are disputed across sources. Its Attio fit is unverified in our research, so integration depth would need to be confirmed directly.

Lines

5 or 10 concurrent (sources conflict)

Connection claim

sub-0.5s

Seat minimum

reported 9 seats, disputed across sources

Pros

• +AI-powered parallel dialing built for enterprise sales teams
• +High concurrent-line capacity for large outbound floors

Cons

• –Quote-only pricing, no published per-seat figure
• –Reported nine-seat minimum blocks the small teams that make up much of Attio's user base

Best for: Large SDR organizations with procurement budgets

Editor's Pick · 03

Nooks

Quote-only

Nooks is an AI dialer and call workspace with a toggle between one-to-one and three-to-five line parallel dialing, plus coaching and analytics features aimed at SDR teams. Pricing is quote-only, and a June 2026 comparison and an Airbase case study document its enterprise orientation. The same Attio caveat applies as the rest of the field: no documented Attio integration in our research, so verify before buying. It is better suited to mid-market and above than to the small teams Attio typically serves.

Modes

toggle between one-to-one and 3-to-5 line parallel dialing

Coaching

built-in coaching and analytics features

Pricing

quote-only

Pros

• +AI dialer workspace with a genuine mode toggle
• +Coaching and analytics aimed at SDR team managers

Cons

• –Quote-only pricing
• –No documented Attio integration in our research

Best for: Mid-market and enterprise SDR teams wanting coaching and analytics in the dialer

Salesfinity

$299/user/month on its product page

Salesfinity offers five parallel lines at $299/user/month on its product page, with conflicting blog pricing of $200 US and $250 international, and its Lightning Mode claims a 600ms median connection speed dated May 18, 2026. That price is more than double CallCloud's five-line plan at $125/seat/month for the same line count, which is the concrete tradeoff a cost-conscious Attio team should weigh. No seat minimums are documented, but the per-seat price is the steepest published figure in this roundup, and Attio integration is unverified in our research.

Lines

Lightning Mode claim

Pros

• +Dedicated five-line parallel dialer with a published price
• +No seat minimums documented

Cons

• –More than double CallCloud's five-line price ($125/seat/mo) for the same line count
• –Conflicting published prices across its own pages

Best for: Enterprise teams that want a dedicated parallel dialer at any price

Editor's Pick · 05

PhoneBurner

$140-$215/user/month

PhoneBurner is a well-established sequential power dialer at $140 to $215/user/month, one line only, roughly 80 dials per hour, with one-click voicemail drop on every plan, a feature CallCloud and several others in this roundup do not document. The honest tradeoffs: no parallel mode at any tier, and DNC.com scrubbing requires a separate subscription rather than being included. It wins a named niche, sequential dialing with voicemail drop for teams that live on voicemail response rates, but it is outclassed on line count and price by CallCloud's $125 five-line plan. Annual billing discounts apply, so month-to-month flexibility is limited, and its Attio fit is unverified.

Mode

sequential power dialing, one line only

Throughput

roughly 80 dials/hour

Voicemail drop

one-click, on every plan

Billing

annual discounts apply

Pros

• +Well-established sequential dialer with voicemail drop on every plan, a feature CallCloud and several others do not document
• +Unlimited calling at its price point

Cons

• –No parallel mode at any tier
• –DNC.com scrubbing requires a separate subscription rather than being included

Best for: Teams whose response rates depend on voicemail drop

Editor's Pick · 06

Trellus

$34.99 (conflicting $149.99 listing exists)

Trellus is a budget dialer listed at $34.99, with a conflicting $149.99 listing in our research, that also appears in Chrome-extension comparisons for embedded CRM dialing. The price makes it a reasonable pilot tool for a founder testing cold-calling volume on a small budget before committing to a fuller platform. The pricing conflict itself is a diligence flag, and feature depth at the entry tier is thinner than the platforms above. Its Attio integration is not documented in our research.

Price

Pros

• +Lowest listed price in the roundup by a wide margin
• +Reasonable pilot tool for testing call volume on a small budget

Cons

• –The pricing conflict itself is a diligence flag; confirm current pricing
• –Feature depth at the entry tier is thinner than the platforms above
• –No documented Attio integration in our research

Best for: Budget-first founders testing cold-call volume before committing to a platform

Editor's Pick · 07

Kixie

Quote-only for its dialer tiers

Kixie is a sales engagement dialer with up to four concurrent lines on its Multi-Line PowerDialer, in-session mode switching, and SMS engagement alongside calling. It publishes no dollar price for its dialer tiers in our research, so it cannot be benchmarked against CallCloud's published $60/$125 pricing, and its line count tops out below CallCloud's five. Founded in 2013, it has a longer track record than newer entrants. Its Attio fit is unverified in our research.

Lines

up to 4 concurrent on its Multi-Line PowerDialer

Modes

in-session mode switching

Founded

2013

Pros

• +SMS engagement alongside calling in one platform
• +Longer track record than newer entrants, founded 2013

Cons

• –Publishes no dollar price for its dialer tiers, so it cannot be benchmarked against published rivals
• –Line count tops out at 4, below CallCloud's 5

Best for: Teams wanting SMS engagement alongside calling in one platform

Who should pick what:

1. 01Solo reps and small teams dialing from Attio should default to CallCloud's month-to-month plans.
2. 02Large SDR orgs with nine or more seats and procurement budgets should evaluate Orum or Nooks.
3. 03Teams needing voicemail drop above all should look at PhoneBurner.
4. 04Budget-first testers should pilot Trellus.
5. 05Teams wanting SMS plus dialing in one platform should quote Kixie.

Apply this article's decision rule before any subscription: ask each vendor for a live sync demo against your Attio workspace, then run a two-week pilot on identical call lists. The vendor that syncs cleanly and proves its connect-rate and latency claims on your data is the right dialer for Attio, regardless of where it sat in this ranking.
