No. Your agent covers the hours your office is closed and the routine questions, so your staff can focus on the calls that need a person.
No. Your secretary knows which family just lost a parent, which volunteer needs a gentle nudge, and which call the pastor needs to take personally. That's ministry, and no software does it.
What we handle is the other kind of call. Service times. Directions. Office hours. The same handful of questions, asked again on Sunday morning while your secretary is helping a first-time visitor find the nursery.
You set the schedule. When your secretary is at her desk, calls ring to her exactly as they do today. When she's off — evenings, weekends, Sunday services, the week between Christmas and New Year's — your agent picks up instead of voicemail.
Most church offices describe it the same way: it gave their staff back the interruptions, not their job.
