Call routing behavior

During business hours

Agent accepts calls immediately
Call proceeds normally
Full conversation capabilities available

Outside business hours

Inbound calls:

Platform does not automatically reject based on schedule
Use a start webhook to handle after-hours calls
Alternative: Disable agent entirely during after-hours

Scheduled outbound calls:

Calls are queued and wait for business hours
Scheduler calculates next available time
If deadline passes before working hours resume, call is canceled

Queue behavior

Situation	Result
Call scheduled outside hours	Queued until business hours resume
Deadline exceeded while queued	Call canceled
Multiple calls queued	Processed in priority order
