The platform integrates with existing phone systems, customer databases, and business tools. It supports over 18 languages and meets important security standards like HIPAA and GDPR. Businesses can use these voice agents for customer support, sales calls, appointment scheduling, lead qualification, and many other phone-based tasks without needing large call center teams.
