The Short Answer

These four are sold differently. VICIdial is open-source software with no license fee that you run yourself or buy hosting for. Five9 publishes two per-user plans with a 50-seat minimum, Convoso gives custom quotes, and ReadyMode lists per-license monthly and annual plans.

Each vendor lists its own dialing modes and compliance tools, and no listing is a promise that a campaign is compliant. The table below puts them side by side in the vendors' own words, read on October 1, 2026.

VoiceOI does not replace any of them. It adds AI voice bots to a floor that already dials, as VICIdial remote agents or over SIP.

VICIdial vs Five9

Five9 calls itself a "Call & Contact Center As A Service (CCaaS) Provider" and describes "inbound, blended, and outbound calling software." VICIdial's own site calls it an "Open-Source Contact Center Solution" that handles inbound and outbound calls as well as inbound email and website chat in one web interface (VICIdial Group).

The clearest difference is how each is priced. Five9 publishes two per-concurrent-user plans, $119 for Digital and $159 for Core, with the higher plans on request, and its page says "Minimum of 50 seats" (Five9 pricing). VICIdial's software has no license fee, so its cost is servers or hosting, carrier minutes, setup and admin time; see how much VICIdial costs.

VICIdial vs Convoso

Convoso describes "a comprehensive cloud-based solution" with "predictive and power dialing" among its capabilities. Its pricing page does not list prices; it says Convoso provides customized solutions "based on each customer's unique needs", which it gives as the number of seats, features and integrations, and that it "primarily offers annual plans" (Convoso pricing).

Because its price comes from a quote, the fair comparison is a quote for your seat count set against the total cost of running VICIdial. Ask the quote to state what carrier fees and add-ons are billed separately, since the page says they are.

VICIdial vs ReadyMode

ReadyMode describes "all-in-one predictive dialer software" with a hybrid-cloud architecture that combines "the flexibility and easy access of the cloud, along with the control and reliability of an in-house system" (ReadyMode). It lists preview, power, progressive and predictive dialing.

Its pricing page lists Starter at $239 per license per month billed monthly or $199 billed annually, and iQ at $299 or $249, and says annual plans are "paid upfront for a 12-month term and automatically renew each year" (ReadyMode pricing). Starter is listed for one or more licenses, so unlike Five9 there is no 50-seat floor on that page.

Four Questions That Decide Between Them

Work through these before you compare feature lists.

1
Who will run the platform?
On VICIdial, you or a host run the servers, and VICIdial's own documentation calls server scaling and dimensioning "one of the hardest parts of ViciDial" (ViciBox docs). Five9 sells a contact-center-as-a-service platform, and Convoso and ReadyMode describe cloud and hybrid-cloud products.
2
What does it cost at your seat count?
Price your size, not the entry price. Five9's page sets a 50-seat minimum, ReadyMode starts at one license, Convoso quotes, and VICIdial's cost is hosting, minutes, setup and admin time.
3
How much compliance tooling do you want built in?
Each vendor lists its own tools, and a tool in a feature list does not make a campaign compliant: the law applies to the caller. For the US abandoned-call rule and what vendors mean by predictive, power and progressive dialing, see types of call center dialers.
4
Do you want AI voice bots on outbound calls?
You do not have to switch dialers to add them. VoiceOI bots join VICIdial campaigns as remote agents (how that works), and the built-in bot dialer works through any SIP carrier. VoiceOI has not published integration guidance for Five9, Convoso or ReadyMode.
