RingCentral vs Zultys (2026): which should you pick?

Pick RingCentral if

• Fits if you want calls, fax, meetings and chat from one company on one bill
• Works for Microsoft Teams shops that want RingCentral calling inside Teams

Look elsewhere if

• Tight if you text customers a lot, with 25 texts a person a month on Core
• Pricey if you add the extras: AI Receptionist from $39, SMS Booster $25, Call Queues Booster $35
• Not for you if you want to try texting first, since it isn't in the free trial
• Tight if you want calls recorded automatically or logged in a CRM, as both need Advanced at $25
• Watch out: listed prices are for 1-5 users, they change for 6-100, and texting needs TCR registration that may carry fees

Pick Zultys if

• Works for contact centers that want the dialer in the same app as the phones

Look elsewhere if

• Not for you if you want to buy direct, because it says it sells through channel partners
• Watch out: the AI Receptionist and some AI tools are separate or newer products with no price shown
• Watch out: no free plan or trial is listed

RingCentral

• Texting needs TCR registration, which may carry fees, and is not available during the free trial.

Zultys
