# Setting up phone numbers

## Setting up phone numbers

Connect an existing phone number to a Workflow, then choose how to handle calls after hours.

## Open a phone number

Start in Phone Numbers. Your line is here, marked Needs workflow. Open it.

## Connect the Workflow

Open Settings. The AI Assistant card sets the Workflow this number answers with. Choose Patient Enrollment, so a caller lands in the enrollment steps. Save changes.

## Choose what happens after hours

In the Voice card, choose what happens when a call comes in. Pick Voicemail, then set it to Off-hours only — which follows the business hours and timezone in workspace Settings. The summary confirms it: voicemail off-hours, the assistant during business hours. Save changes.

## Business hours and after-hours calls

Your number now answers with Patient Enrollment during business hours and takes voicemail after them. More at docs.gravityrail.com.
