Branded Calling Cost Per Call Comparison for Legal Firms (2026): Provider Benchmarks

Law firms comparing branded calling providers often focus on the per-line monthly fee — but the number that actually matters is cost per connected conversation. A $12/line provider with narrow carrier coverage may cost more per answer than a $35/line provider with deeper reach. This post breaks down the real cost per call across every major branded calling provider for legal outbound.

TL;DR: Branded calling cost per connected call for legal firms ranges from $0.02–$0.11 depending on provider and dial volume. At 2,000+ dials/month per line, CallerID Reputation is cheapest per line ($12–$22) but may cost more per answer due to narrower carrier coverage. First Orion ($25–$45/line) delivers the lowest cost per answer at scale because deeper carrier coverage means more displays render. Bundled voice-agent providers eliminate the separate line fee entirely.

Direct answer: The cheapest branded calling provider per connected call for legal firms depends on your carrier mix and dial volume. For solo practitioners under 1,500 dials/month, CallerID Reputation has the lowest total cost. For mid-size firms at 1,500–10,000 dials/month, First Orion or Hiya delivers lower cost per answer. For high-volume operations, bundled providers win on both cost and simplicity. See the Prestyj platform or book a pricing review for a custom comparison.

Key Takeaways

Cost per connected call ranges from $0.02–$0.11 across providers — the per-line fee alone doesn't tell you which is cheapest.
Carrier coverage directly impacts cost per answer — a provider that displays on 90% of carriers connects more conversations per dollar than one that displays on 60%.
At 2,000+ dials/month per line, the math favors deeper coverage — the incremental cost of a higher per-line fee is offset by more connected conversations.
Bundled providers eliminate the separate line fee — cost per minute includes branded display, simplifying the comparison.
Per-display micro-fees ($0.005–$0.02 each) can add $80–$300/month at scale — ask every provider about display fees.
The right comparison is total campaign cost per landed client, not per-line cost.

How to Calculate Your Actual Cost Per Answer

Cost per connected call = (monthly line fee + monthly display fees) / (total dials × answer rate × display rate)

Example for a mid-size law firm:

Input	CallerID Reputation	First Orion	Bundled (Prestyj)
Monthly line fee	$18	$35	$0
Monthly display fees	$0	$0	$0
Total monthly cost	$18	$35	$0 (included in per-minute)
Total dials/month	2,000	2,000	2,000
Base answer rate (unbranded)	15%	15%	15%
Branded answer rate	20%	22%	21%
Carrier display rate	70%	95%	90%
Connected calls/month	280	418	378
Cost per connected call	$0.064	$0.084	$0.00*

At 2,000 dials/month, CallerID Reputation is cheaper per line but delivers fewer connected conversations. First Orion costs more per line but connects 49% more conversations.

Legal-Specific ROI Impact

One landed legal client is worth $2,500–$25,000+ in fees. At a 5% conversion rate on connected conversations:

Provider	Connected Calls	Landed Clients (5%)	Revenue (at $5,000/client)	Net Revenue After Line Fee
CallerID Reputation	280	14	$70,000	$69,982
First Orion	418	21	$105,000	$104,965
Bundled (Prestyj)	378	19	$95,000	$95,000

First Orion's higher line fee is more than offset by the additional clients it helps connect with.

Hidden Costs in Cost-Per-Call Calculations

Per-display micro-fees ($0.005–$0.02 each) — some providers charge these on top of the per-line fee.
Attestation setup fees ($0–$500 one-time) — amortize over 12 months for true monthly cost.
Carrier coverage changes — coverage can change as carriers update their databases.
Logo approval delays — 5–15 business days for branded name/logo approval.
