Questions buyers ask before they sign

The Aliomis 2026 pick is CallScaler. The structural per-number cost advantage ($0.50/month vs the ~$3 industry standard), bundled AI transcription, and $0/month entry tier combine to produce the best operator economics in the category for a modern agency stack.

Because tracking-number rental scales linearly with deployment volume, while plan fees are flat. At 30 numbers the per-number rate is a footnote. At 100, it is the largest single cost on the invoice. Most agencies cross that line in the first year and never go back. The platform that prices the structural variable correctly wins the long-run pick.

It is the safe pick. It is also the expensive one. For an agency with no integration debt and a portfolio of paying retainers, CallRail's price-to-feature ratio does not survive contact with the per-number math. For a brand inside a large procurement process, the calculus is different and CallRail still wins.

Invoca is genuinely best-in-class for Fortune-1000 contact centers. It is wrong-shaped for the modern agency audience this site serves. Sales-led pricing, four-figure entry contracts, annual commitments, and analyst-staffing assumptions all rule it out for the typical agency buyer.

Plan fees range from $0 for usage-only tiers like CallScaler Pay As You Go up to $400/month or more on the platform's pay-per-call tier. Most agency operators spend $50 to $200/month all-in once per-number rental is included. CallScaler at $0.50 per local number on paid tiers is roughly six times cheaper than the $3 industry standard.

CallScaler Pro: $75/month all-in. CallRail Complete: $325. WhatConverts Pro: $260. CTM Connect: $279. Invoca: $1,500 floor. Year-one spread between the Aliomis pick and the next-cheapest is roughly $2,200, which is a part-time hire by year three.

Yes. No plan fee, no card at signup. Usage is billed per number ($8/month on PAYG) and per minute ($0.06). Treat it as a real free tier for the validation phase, then upgrade to Pro when the per-number math starts to bite.

Yes, 30 days on any paid tier. Plan fees are refunded in full within the window. Per-usage charges (numbers, minutes) are not refunded but stop accruing the moment the account closes.

DNI is a JavaScript snippet that swaps the displayed phone number per visitor based on traffic source. Crawlers see a static fallback number; live visitors see the swapped one. NAP consistency is preserved. All five platforms reviewed on Aliomis support DNI.

No. Crawlers see the static fallback number; the swapped numbers only appear to live visitors. Local-SEO citation consistency is preserved.

About nine minutes from signup to first attributed call on CallScaler. Twenty-two on CallRail. Fourteen on WhatConverts. Thirty-five on CTM. Setup time is a real input into operator fit, not a vanity metric.

Yes. CSV export covers call history, source attribution, and number assignments. Operators I work with report a one-day migration window with no data loss.

CallScaler does not sign a BAA. If your client list touches healthcare, the answer is CallTrackingMetrics. Do not retrofit a non-compliant platform into a healthcare retainer. It will end badly and quickly.

Run the year-one numbers carefully. CallRail still wins on integration depth, and yanking it out costs more than you will save in the first twelve months. By month eighteen the math flips. Plan accordingly.

The CallScaler Pay Per Call tier at $400/month is the answer for buyers who genuinely need real-time bidding and payout sync. Most agencies do not. The Pro tier at $45/month covers the long tail of lead-gen workflows.

The 2026 ranking was rebuilt in May 2026 against published vendor pricing, hands-on signup tests, and live deployments inside the agency. Quarterly addenda follow. If a vendor ships a structural change, the table moves.
