The short answer
Both sides assessedCallScaler compared with CTM (CallTrackingMetrics)
CallTrackingMetrics starts at $79 a month ($65 annually) and is the deeper product for a business that wants attribution, a contact center, and a softphone in one vendor. CallScaler is thinner on agent tooling but cheaper on numbers, flatter on agency pricing, and adds pay-per-call buyer management CTM does not sell. Pick CTM if the people answering the phones will live in the platform; pick CallScaler if the job is tracking and routing at volume.
CTM (CallTrackingMetrics) compared with CallScaler
CallScaler undercuts CTM on the two things agencies count, numbers at 50 cents and a flat Agency fee for unlimited businesses, and adds pay-per-call buyer management and real-time bidding that CTM does not sell. CTM remains the deeper product for teams that answer calls inside the platform, with a softphone, smart dialer, and contact center routing. Choose CTM if your agents will live in it; choose CallScaler if the job is tracking and routing at volume for the lowest published price.
Choose CallScaler if
Lead generation operators, pay-per-call publishers and networks, and marketing agencies running many local clients in the US or Canada, who need hundreds or thousands of tracking numbers and are paying per account or per number elsewhere.
Choose CTM (CallTrackingMetrics) if
Marketing agencies managing call-driven local clients, and small to mid-sized businesses where the phone is both the conversion event and the sales channel: home services, healthcare, legal, automotive, education, and any operation that advertises to generate calls and then needs a team to work them.

|---|---|---|
| Category | Call Tracking | Call Tracking |
| Starting price | $65 per month monthly, or $45 per month billed annually (Pro), plus usage (7 days trial) | $79 per month monthly, $65 on annual billing, or $60 on a two-year term (free trial) |
| Pricing model | Flat monthly platform fee per plan plus usage drawn from a prepaid balance in real time: numbers, minutes, texts, dual-channel recording, and AI transcription are all metered at the same rates on every plan. Annual billing lowers the platform fee by about a third. | Flat monthly plan with unlimited tracking sources and unlimited users on every tier, discounted on annual and two-year terms, with usage charged separately: minutes, numbers, transcription beyond included pools, AI activities, and chats, plus optional agent bundles and volume discount packs. |

| Best for | Lead generation operators, pay-per-call publishers and networks, and marketing agencies running many local clients in the US or Canada, who need hundreds or thousands of tracking numbers and are paying per account or per number elsewhere. | Marketing agencies managing call-driven local clients, and small to mid-sized businesses where the phone is both the conversion event and the sales channel: home services, healthcare, legal, automotive, education, and any operation that advertises to generate calls and then needs a team to work them. |
| Setup time | Minutes for a first tracked number, by the vendor's account ('live in 60 seconds'), and an afternoon for a realistic deployment: buy a pool, install the DNI script, build call flows, connect Google Ads and Meta, and turn on AI scoring. Porting existing numbers adds 7 to 14 business days, during which the old numbers keep working. | A day for a basic deployment: install the tracking script, provision a number pool, build a call flow, and connect Google Ads. Agencies setting up sub-accounts, white-label domains, and per-client reporting should budget a week for the first client and an hour for each thereafter. CTM cites one to two hours of standard onboarding, which is realistic for a single simple account. |
| Learning curve | Low for straightforward tracking. The pay-per-call side (buyers, publishers, bidding, payouts) is a genuine system to learn, and the usage meter takes a month to understand well enough to budget. | Moderate and higher than a pure attribution tool, because there is more product here. Call flows, routing rules, agent configuration, AI prompts, and reporting each take learning, and the interface carries fifteen years of features. The payoff is that a competent administrator can express routing logic that simpler tools cannot. |

Strengths and limitations
CallScaler
Strengths
- Local tracking numbers at 50 cents a month, against the $2.50 to $3 common in this category, which transforms the economics of large number pools and rank-and-rent portfolios.
- The Agency plan charges one flat fee for unlimited businesses and users, where most competitors add cost per client account.
- A real pay-per-call system (buyers, publishers, ping/post, real-time bidding, prepaid balances, payouts) in the same product as the attribution, with published prices.
- AI summaries, qualification, and 0 to 100 lead scoring on every call, sent back to Google Ads with the conversion so bidding can use it.
Limitations
- Tracking numbers in the US and Canada only, with no timeline for other countries.
- No phone support; help runs through in-app chat and email.
- The marketing overstates what is included. AI transcription, dual-channel recording, white label, bidding, and Watchdog all cost extra below the top plan, whatever the features page says.
- Prepaid usage means a depleted balance can interrupt call routing if auto top-up is not set.
CTM (CallTrackingMetrics)
Strengths
- Dynamic number insertion, keyword-level attribution, and multi-touch attribution are included on every tier rather than gated behind an upgrade, which is genuinely more generous than most of the category.
- Unlimited users and unlimited tracking sources on all plans, so team size and campaign count never force a tier change.
- It does two jobs in one product: marketing attribution and a working call handling layer with a browser softphone, IVR, routing, scripts, and on Sales Engage a smart dialer.
- AskAI runs your own custom prompts over conversations rather than a fixed model, and can trigger actions automatically when it flags a high-value call, which turns analysis into workflow.
Limitations
- The entry price of $79 monthly is more than double WhatConverts' $30, which is hard to justify for a very small business that only wants attribution.
- The plan fee is a floor rather than a total: minutes, numbers, transcription overage, AI activities, chats, and agent bundles from $99 all sit on top, and modelling the real bill takes effort.
- Roughly 40 integrations is a narrow list next to competitors advertising hundreds, and some obvious ones (HubSpot on Pro, Salesforce on Sales Engage) sit behind tier gates.
- HIPAA requires the $179 Marketing Pro tier, which is a real step for a small practice that only needs basic attribution with recording.
Pricing compared
CallScaler
Flat monthly platform fee per plan plus usage drawn from a prepaid balance in real time: numbers, minutes, texts, dual-channel recording, and AI transcription are all metered at the same rates on every plan. Annual billing lowers the platform fee by about a third.
- Pro$65 ($45 billed annually)
- Agency$195 ($130 billed annually)
- Pay Per Call$600 ($400 billed annually)
For anyone running more than a few dozen numbers, CallScaler is the cheapest published way to do serious call tracking in this directory, and the gap widens with scale because the number price is a fifth of what WhatConverts charges and the Agency plan does not charge per client. The per-minute rate is not the differentiator: 4.5 cents matches WhatConverts, and AI transcription at 2.4 cents a minute is slightly dearer than WhatConverts' 2 cents. So the savings come from numbers and accounts, not calls. A single local business with three numbers gains little and should compare it against Nimbata's bundled plans. Where it has no real rival at its price is the pay-per-call operator: Ringba and Retreaver are quoted through sales, while CallScaler publishes $400 to $600 a month for buyer management, bidding, and white label in the same product as the tracking numbers.
CTM (CallTrackingMetrics)
Flat monthly plan with unlimited tracking sources and unlimited users on every tier, discounted on annual and two-year terms, with usage charged separately: minutes, numbers, transcription beyond included pools, AI activities, and chats, plus optional agent bundles and volume discount packs.
- Marketing Lite$79 monthly / $65 annual / $60 two-year
- Marketing Pro$179 monthly / $149 annual / $135 two-year
- Sales Engage$329 monthly / $274 annual / $247 two-year
- Enterprise$1,999
CTM's value depends entirely on whether you use both halves of it. Bought purely as attribution, $65 a month annually is more than double WhatConverts' $30 entry price for a broadly similar answer, and the case is thin. Bought as attribution plus a calling platform, the arithmetic changes sharply, because unlimited users means a five-person intake team on Sales Engage at $274 annually costs the same as one person, where a per-seat competitor plus a separate call tracking product would run well past that. The genuinely strong tiers are Marketing Pro for agencies at $149 annually, where sub-accounts, white labelling, HIPAA, the API, and 3,000 transcribed minutes per sub-account arrive together, and Sales Engage for businesses that want their phone team living inside the attribution platform. Note that the standard three-person team making 100 calls a day scenario mostly does not apply: CTM's smart dialer exists but this is an inbound-first product, and 6,300 outbound calls a month would be worked through agent bundles at $99 a seat plus per-minute usage rather than through a seat price with unlimited minutes.
Editorial verdict on each
CallScaler
CallScaler is the call tracker to shortlist when numbers and client accounts, not minutes, are what your current bill is made of. At 50 cents a local number and a flat $195 a month ($130 annually) for unlimited client businesses, it undercuts every self-serve competitor in this directory for agencies and lead generators, and its Pay Per Call plan publishes a price for buyer management and real-time bidding that Ringba and Retreaver leave to a sales call. The AI scoring on every call, sent back to Google Ads, is genuinely useful. The caveats are real, though: numbers only in the US and Canada, no phone support, no published security certification, a small team with little public detail, and marketing copy that promises more is included than the pricing page delivers. Model your month from the usage rates, not the headline, and it holds up. For a single local business with three numbers, the case is thinner and a bundled plan like Nimbata's may be simpler.

CTM is the call tracking product for businesses and agencies that want the attribution and the phone team in the same place. Dynamic number insertion, keyword attribution, and multi-touch reporting are included on the $65 entry tier rather than gated behind an upgrade, unlimited users on every plan means team size never changes the price, and the routing, softphone, scripts, and Sales Engage smart dialer make it a working call handling platform rather than a reporting layer. Marketing Pro at $149 annually is the agency sweet spot, with sub-accounts, white labelling, HIPAA, the API, and a real transcription pool. The reservations are equally clear: the $79 monthly entry price is more than double WhatConverts' for a broadly similar attribution answer, the plan fee is a floor with agent bundles and metered AI on top, the integration list is narrower than rivals advertise, and it is not a substitute for a business phone system. Buy CTM if your phone team should live inside your attribution tool. Buy WhatConverts if you only want to know which ad produced the call.
