• A client calls about an installation date.
• The designer calls a client to review selections.
• A homeowner calls about a kitchen redesign.

Calls after closing time

After-hours calls are usually project updates that can wait until morning.

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