Frequently Asked Questions

OnCallClerk vs Presto Voice: which should you choose?

Presto Voice and OnCallClerk serve completely different markets: Presto is an enterprise-grade drive-thru automation for QSR chains (recently adopted by Dairy Queen) with a focus on upselling and revenue lift, while OnCallClerk is a budget-friendly AI phone receptionist for SMBs needing 24/7 call coverage. Choose Presto if you run a multi-location fast-food chain; choose OnCallClerk if you're a solo tradesperson or small practice wanting an affordable virtual assistant.

Which tool is better for a single restaurant with no drive-thru?

Neither is ideal. Presto focuses on drive-thrus; OnCallClerk is a virtual receptionist but not tailored for dine-in. You may want a general AI phone agent or a restaurant-specific call handling service.

Can OnCallClerk handle high call volumes like Presto?
