The best Nooks alternative for parallel dialing is CallCloud: at $125 per seat per month, month to month, with up to 5 simultaneous lines, it is the cheapest published-price 5-line parallel dialer among the specialists we surveyed. Salesfinity lists $299 per user for the same line count, and Nooks, Orum and Koncert publish no per-seat price at all, which makes any head-to-head cost comparison with them impossible before a sales cycle.
The honest caveat comes first: the market's most-reviewed options hold bigger review bases and longer track records than the newer entrants. Nooks carries a 4.8/5 G2 average from 1,698 reviews; Orum carries 4.6/5 from 1,099. CallCloud, founded in 2022, has no verified G2 review average published yet. This ranking therefore weighs published pricing transparency and the actual dialing mechanism over brand recognition, and we name where each option is thin rather than hiding it.

One rule governs everything on this page, and it is the rule most comparison pages skip: published prices across this category buy different dialing mechanisms, so they are not interchangeable. A parallel dialer places multiple simultaneous attempts per rep and bridges the first answer. A power dialer works a list fast but one contact at a time. A predictive dialer paces calls against an agent pool. A human-assisted service puts people between your rep and the phone system. Before you compare any two dollar figures below, confirm they buy the same mechanism.

// SectionHow we ranked these Nooks alternatives
Every price, line limit and review count here comes from vendor pricing pages and G2 snapshots gathered in August 2026. Where vendor pages conflict with each other, we show both figures and tell you which question to ask. Three criteria drove the ranking:
Whether pricing is published. Quote-only vendors make per-seat comparison impossible before a sales cycle, so a published price is itself a feature.
The contracted simultaneous-line limit per rep in a specific dialing mode. Not a marketing page's number, the number in the contract.
Integration depth with the stack a Nooks refugee is likely already running: Salesloft, Outreach, HubSpot, Salesforce.
One diligence note applies to every option on this page equally, including CallCloud: get the contracted line limit in writing, and run a same-list, same-window pilot before committing to anything.
Get it in writingask each vendor for the contracted simultaneous attempts per rep, per calling mode, not the number on the marketing page.
Price the same seat countrequest the complete monthly price for the same number of active reps, including base seats, minutes, numbers and add-ons.
Pilot the same listrun each finalist over the same call list in the same time window.
Measure conversations, not dialsrecord dials, live conversations, connected talk minutes, meetings set and calls lost during bridging.
We excluded tools whose dialing mode does not match Nooks' core function, and we flag mechanisms that are adjacent rather than equivalent. PhoneBurner ($140 per user per month and up, billed annually) is sequential-only, one contact at a time. Readymode's 20+ concurrent calls belong to predictive mode paced against an agent pool, not to SDR parallel dialing. Both are fine products; neither is a Nooks substitute.
// SectionCallCloud: the cheapest published 5-line parallel dialer
CallCloud's parallel web dialer places up to 5 simultaneous calls per rep over a continuously connected audio bridge built for zero-lag pickup, with unlimited calls, minutes, research briefs, AI notes and number rotation included at $125 per seat per month. Its structural difference from every rival here: it runs alongside your existing sales engagement stack rather than replacing it.
Lines per rep
up to 5, dialed simultaneously
Contract
month to month, no published seat minimum
Included
unlimited calls, minutes, research briefs, AI notes, transcription, recording, live-listen, number rotation and reputation management
Integrations
native sync with HubSpot, Salesloft, Pipedrive, Gong, GoHighLevel; separate $60 Power Dialer Extension inside Salesloft, Outreach and HubSpot
Pros
+Cheapest published 5-line parallel price we found: $125 versus $299 at Salesfinity
+Month-to-month terms with no published seat minimum, versus Orum's nine-seat floor
+Works alongside your existing engagement stack instead of replacing it
+Continuously connected audio bridge designed for zero-lag pickup
Cons
–Salesforce native sync is in final testing; Outreach native sync on the parallel product is still forthcoming, though the $60 extension supports Outreach today
–No verified G2 review average is published yet, a smaller review footprint than Nooks' 1,698 reviews
Best for:SDR teams that want 5-line parallel dialing alongside Salesloft, Outreach or HubSpot
The company claims 5x lines, 0ms lag on pickup, a 2x connection rate versus competitors, and more than 1,000 reps using it daily, with trusted-by logos including OneSignal, Cyberhaven, EliseAI and Observe.AI. Those are vendor claims, not independently measured results, and we treat them as such. The verifiable facts are the ones on the pricing page: $125 per seat, month to month, 5 lines, unlimited calling, and phone numbers billed at cost.
The structural angle matters more than the price. A team that lives in Salesloft or Outreach does not have to choose between its sequencer and its dialer. The $60 Power Dialer Extension adds one-line power dialing inside those platforms, and the $125 parallel product natively syncs with HubSpot, Salesloft, Pipedrive, Gong and GoHighLevel. Salesforce sync is in final testing and Outreach native sync on the parallel product is forthcoming.
Founded in 2022, CallCloud has the shortest track record on this list, and its published review base is smaller than Nooks' 1,698-review footprint. If your team buys on social proof, that is a real consideration, and it is the main one.
// SectionOrum: the enterprise benchmark with a configuration catch
The pick · 02
Orum
★ 4.6 / 5
Quote-only, nine-seat minimum
Orum is the enterprise benchmark for AI dialing, with unlimited dials, data enrichment, answer detection and calling into 160+ international markets. The catch is configuration: pricing is quote-only with a nine-seat floor, and its own pages disagree on the parallel-line limit.
Lines per rep
5 or 10 depending on the page, verify in contract
Contract
quote-only, nine-seat minimum, free trial capped at 500 dials
Coverage
US, Canada and 160+ international markets
Extras
up to 10 caller IDs per month, recordings, AI summaries, coaching features
Pros
+Unlimited dials on paid plans, with both power and parallel modes
+International coverage in 160+ markets, the widest on this list
+Large review base: 4.6/5 from 1,099 G2 reviews; founded 2018 with $51M recorded financing
Cons
–Quote-only pricing with a nine-seat minimum blocks small-team comparison entirely
–Its own pages conflict on the parallel-line limit: one says 5, another says 10
Best for:Larger SDR orgs that need international coverage and a deep coaching stack
The configuration catch our research flagged is worth repeating because it is the exact question a buyer should ask. One Orum page says up to 5 parallel lines; another says up to 10. Until the contracted limit is in writing, neither number belongs in a comparison table, and a published-price rival cannot be judged against a figure the vendor itself publishes twice.
One more clarification on a widely quoted line: Orum's statement that most reps spend less than 20% of their day in conversations describes the baseline problem it sells against. It is not a measured post-purchase result, and treating it as one is how comparison pages mislead.
Best fit: larger SDR organizations that need international coverage and a coaching stack, and that can absorb a nine-seat minimum.
// SectionSalesfinity: published pricing at the top of the market
Salesfinity publishes what most rivals hide: a self-serve Gold tier at $299 per user per month for up to 5 parallel lines and 10 rotating caller IDs. It is the most transparent of the established specialists, and the most expensive per line.
Lines per rep
up to 5 (Gold)
Caller IDs
10 rotating
Contract
Gold self-serve; Enterprise and Enterprise Plus custom annual
Integrations
Salesforce, HubSpot, Outreach, Salesloft, Apollo
Pros
+Fully published, self-serve pricing, rare in this category
+4.8/5 G2 average, the highest on this list, though from a small base of 122 reviews
+10 rotating caller IDs included in Gold
Cons
–$299 per user is well over twice CallCloud's published price for the same 5-line capacity
–Advertised unlimited dials and lines are subject to fair-use terms, so 5 lines is the working spec
–No calls-per-day or talk-time claim published on its pricing page
Best for:Teams that want a self-serve, established parallel specialist and can pay for it
The comparison a cost-conscious Nooks shopper will actually make is simple: Salesfinity Gold and CallCloud's parallel plan both offer 5 lines, at $299 and $125 per seat respectively. Salesfinity brings a longer established presence and a 4.8/5 rating, though from only 122 reviews. Whether that record is worth $174 per seat per month is a fair question to put to both vendors in a pilot.
Best fit: teams that want a self-serve, established parallel specialist with a strong if small review base, and can pay for it.
// SectionTrellus: the overlay option if you keep your existing phone system
The pick · 04
Trellus
$59.99 to $149.99/month by tier
Trellus is an AI dialer overlay for teams already paying for telephony inside Salesloft, Outreach, HubSpot or Apollo. Its BYOD tier at $59.99 is the cheapest published entry on this page, but the multiline Parallel tier publishes no line count.
Tiers
BYOD Power $59.99, Power $99.99, Parallel $149.99 per month
Lines per rep
not published on the Parallel tier; BYOD is single-line
Requirement
BYOD tier needs an existing HubSpot, Apollo, Salesloft or Outreach phone system
Company
founded 2022, $500,000 recorded financing
Pros
+Three published tiers, including a genuinely cheap BYOD entry point
+Layers onto a phone system you already pay for instead of replacing it
+Marketed directly for Salesloft, Outreach and HubSpot workflows
Cons
–The Parallel tier publishes no line count, so its capacity cannot be compared on paper
–Its pricing page displays $34.99 promotional pricing alongside the tier prices, a conflict to resolve before signing
–No comparable G2 rating snapshot in our research
Best for:Teams already paying for telephony inside their engagement platform
The $34.99 promotional pricing displayed alongside the three tier prices is an internal conflict, not a discount you can bank on. Confirm which number governs and for how long before you sign anything.
Best fit: teams already paying for telephony inside their engagement platform who want to layer parallel dialing on top rather than buy a standalone dialer.
// SectionKoncert: the most dialing modes, at the cost of quote-only pricing
Koncert sells more dialing modes than anyone else here, from a click dialer to 5-line AI parallel, all Salesforce-native and all quote-only. Its 150-200+ dials per hour claim comes with conditions, and its own datasheet says 125+.
Lines per rep
AI Parallel Symphony 1-4; Symphony+ 1-5; Flow and AI Flow single-line
The volume claims need context. Koncert describes roughly 150 to 200+ dials per hour on multiline campaigns, with connect rates of 5 to 15%+, explicitly conditional on list, buyer profile and timing. A separate datasheet says more than 125 dials per hour. These are different pieces of vendor material, not a range you can plan around.
Best fit: Salesforce-centric teams that want to choose among multiple dialing modes inside one platform and are comfortable running a procurement cycle just to learn the price.
// SectionConnectAndSell: when you want humans to navigate the dialing
ConnectAndSell is a different mechanism entirely: human-assisted, AI-optimized connections where the vendor's staff navigates phone systems and gatekeepers and hands your rep a live person. It advertises 100+ dials per hour, and a free one-day Test Drive backs the claim with a trial.
Mechanism
human-assisted, AI-optimized connections via Express Connect and Precision Connect
Trial
free one-day Test Drive
Claim
100+ dials per hour advertised
Company
founded 2007, about $14.9M recorded financing; 4.3/5 from 234 G2 reviews
Pros
+The vendor handles phone systems, IVRs and gatekeepers, so reps only take live conversations
+Free one-day Test Drive lets you measure output before any contract
+Integrations span Salesforce, HubSpot, Dynamics, Outreach, Salesloft, Gong and Chorus
Cons
–No public dollar figure, so per-seat economics cannot be compared on paper
–Human-assisted connections are a different mechanism, so its seat price is not comparable to software-only dialers
Best for:Teams that would rather buy outsourced connection labor than manage dialing software
The RingCentral case study gets quoted often, so it deserves precision. A fast manual caller there made 80 to 120 dials and 4 to 5 conversations a day; with ConnectAndSell's Lightning, the account reported up to 1,000 dials and 50+ conversations. That is one customer's upper-end account with its own lead queue and staffing, not a per-rep guarantee. The seat economics of a service that includes human labor are not comparable to software-only per-seat prices, which is exactly why ConnectAndSell sits last on a parallel-dialer list while remaining the right answer for a team that wants dialing done for them.
// SectionWhich Nooks alternative should you pick?
Applied to the reader types this page actually serves, in order of how common they are:
Teams that want parallel dialing with published pricing and their existing engagement stack intact should start with CallCloud. The $125 parallel seat and the $60 extension cover both mechanisms without a platform migration.
Larger orgs needing international coverage and coaching should get an Orum quote, and get the 5-versus-10 line question answered in the contract.
Teams with existing telephony inside HubSpot, Apollo, Salesloft or Outreach should evaluate Trellus BYOD at $59.99 before buying any standalone dialer.
Salesforce-centric buyers wanting multiple modes should price Koncert, knowing the answer arrives only after a procurement cycle.
Teams that want dialing done for them should try ConnectAndSell's free one-day Test Drive and measure conversations, not dials.
The rule this article opened with, applied one last time: before comparing any two prices on this page, confirm they buy the same dialing mechanism. A $60 power extension, a $125 parallel seat, and a quoted nine-seat Orum deployment are three different purchases, and the comparison pages that treat them as one price list are the reason buyers end up surprised at contract time.
How much does Nooks cost per seat compared to its alternatives?
Nooks publishes no per-seat figure; its pricing page is quote-only. Published prices among its alternatives range from $125 per seat per month at CallCloud to $299 at Salesfinity Gold, while Orum, Koncert and ConnectAndSell are also quote-only.
Is CallCloud cheaper than Nooks and Orum for parallel dialing?
It cannot be compared head to head with either, because Nooks and Orum publish no prices. Against the published prices that exist, CallCloud's $125 per seat for 5 lines is $174 less per seat than Salesfinity's $299 for the same line count.
How many parallel lines does each Nooks alternative support?
CallCloud and Salesfinity each publish up to 5 lines. Koncert publishes 1-4 lines on Symphony and 1-5 on Symphony+. Orum's own pages conflict between 5 and 10, Trellus publishes no line count, and ConnectAndSell is human-assisted with no published per-rep ceiling.
Do Orum and Nooks publish pricing, or is everything quote-only?
Both are quote-only. Orum adds a nine-seat minimum and a free trial capped at 500 dials; Nooks publishes no per-seat figure, so any specific price you see quoted for either vendor is someone's negotiation, not a list price.
Can I use a parallel dialer with Salesloft, Outreach, or HubSpot without switching platforms?
Yes. CallCloud's $60 Power Dialer Extension adds one-line power dialing inside all three, and its $125 parallel dialer syncs natively with HubSpot and Salesloft. Trellus BYOD layers onto an existing phone system in those platforms. Note that the platforms' own native dialers are sequential: HubSpot's sales power dialer is labeled beta, and none of the three documents a Nooks-style per-rep parallel entitlement.
