Auto Attendant vs Traditional Receptionist

ROI: 25-person business saves $34,500-$54,500/year replacing one receptionist.

Auto Attendant vs IVR vs Call Queues

Auto Attendant

Menu-based routing via DTMF, time-based routing, dial-by-name. Use for initial routing and after-hours.

IVR

Advanced self-service with voice input (ASR), data lookups, multi-level menus, transaction processing. Use for account checks, order status, appointments.

3. No Operator Escape — Mistake: No "press 0" option. Fix: Always offer on every menu level.

4. Outdated Information — Mistake: Old holidays, wrong hours, departed employees. Fix: Quarterly reviews, set calendar reminders.

5. Poor Audio Quality — Mistake: Smartphone recording with background noise. Fix: Professional recording or high-quality USB mic, WAV 8 kHz.
