• A general contractor calls about rough-in timing.
• A tenant calls about a burst pipe.

After-hours calls

Emergency calls at night and on weekends are core business, so after-hours routing to an on-call technician or an AI receptionist that takes details matters.

Callata voicemail is transcribed and triaged for urgency, and business-hours routing decides where calls go once you close.
