Why Businesses Add Callis to Their Nextiva System
Key reasons businesses switch from Nextiva to Callis
Replace Human Receptionists
Nextiva provides reliable phone lines and tools, but you still need someone to answer calls. Callis replaces the human receptionist entirely with AI that handles calls 24/7 including scheduling, lead capture, and caller routing.
Never Miss a Call
With Nextiva, missed calls go to voicemail when staff are busy or after hours. Callis answers every call instantly, 24/7/365, so you never lose a potential customer to voicemail.
Save on Staffing Costs
A human receptionist costs $30,000 to $50,000 per year in salary alone. Callis provides 24/7 AI reception for $399 per month, saving businesses tens of thousands annually while providing better coverage.
Automated Scheduling and Lead Capture
Nextiva routes calls but cannot book appointments or capture leads automatically. Callis handles these tasks with AI, integrating directly with your calendar and CRM.
