Fine print
  • The $149.99 Parallel package is a self-contained license, not a $149.99 add-on to a separately purchased Power seat.
  • The pricing page also displays $34.99 beside $149.99 without explaining what the smaller figure represents.
  • A standard credit-based Parallel subscription includes 2,500 Calling Credits per paid seat per week only when that allowance is expressly offered at checkout; the order can specify a different allowance.
  • Included credits are pooled, reset weekly, and expire if unused; answered or connected call legs, including voicemail, consume credits according to provider billing increments.
  • A limit of 2,000 outbound call attempts per user per day applies to Power and Parallel unless otherwise agreed in writing.
  • Legacy minute-based Parallel plans have 3,000 Bridged Minutes per seat per month, pooled across seats; provider rounding applies, and international calls can consume the allowance faster than one-to-one.
  • Above a legacy plan's pooled minute allowance, Trellus may restrict calling or permit continued usage at $0.04 per additional Bridged Minute; running out of credits does not itself authorize that automatic per-minute charge.
  • JustCall's predictive-dialer cost guide lists $249/user/month or $229/user/month billed annually, but its main pricing page calls SalesPro pricing Custom and asks buyers to get a quote.
  • SalesPro has a two-license minimum; the predictive dialer is included rather than charged as a separate add-on.
  • New-plan accounts receive two complimentary phone numbers per account, not per seat; additional numbers are billed monthly at an unstated price.
  • SalesPro's unlimited voice minutes are subject to fair use: scaled telephone operations such as call centers or telemarketing are excluded, and JustCall can impose limits for abuse. No numerical voice-minute ceiling is published.
  • Measured calling usage is rounded up to full minutes; an outbound call receiving answer supervision, including ring time, has a one-minute minimum.
  • International, premium-rate and certain other calls are outside included regional calling; applicable charges can be deducted from JustCall credits.
  • The free trial caps outbound calls at 50 minutes total and calls at seven minutes each.
  • SalesPro's fair-use policy limits one-to-one inbound and outbound SMS to 1,000 segments per user per billing month; that figure is not a voice-minute cap.

Bills are one seat, month to month where sold, on the calculator's model (answered calls billed as one minute each on a per-minute meter). Spam protection, pick-up and the toolkit are what each vendor states, not our own tests. Read from each vendor's pages on 2026-10-09.
