Terms

No quarterly or annual Parallel price is stated.

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.	Koncert directs buyers to request pricing for both Symphony and Symphony+; their monthly and annual seat prices are not stated. The maximum number of parallel lines depends on the package or the customer’s quote or order form. Koncert defines normal business use by the calling patterns of at least 95% of subscribers on the same plan; it does not publish a numerical domestic-calling allowance for these packages. Appointment-setting, lead-generation, telemarketing, call-center and B2C firms require Koncert’s written pre-approval under its fair-use policy. If separately purchased, Group B international calling is limited to 500 minutes per user per month, pooled across the organization; excess calls may incur charges at applicable rates or prompt a plan change. Koncert says customers can purchase and refresh caller IDs, but does not publish a per-number price on its pricing page.

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.
