FAQs

Frequently Asked Questions

A Voice Call API is a programmable tool that lets a business build, automate, and control calling, like IVR, OTP, and click-to-call, from inside its own app or CRM, instead of relying on fixed phone-system hardware. Zapim's Voice API delivers this as a CPaaS (Communications Platform as a Service): REST APIs, SDKs, and a no-code console, entirely over the cloud.

AI automates the high-volume, low-complexity parts of a call — IVR navigation, payment reminders, order-status updates — so human agents only handle complex cases. Zapim's AI layer adds real-time sentiment analysis, live transcription, and automated call summaries, giving support and sales teams data they can act on immediately, not after the fact.

Most voice APIs, including Zapim's, connect through standard REST APIs and SDKs that plug into major CRMs, ERPs, and helpdesk tools without custom middleware. Teams typically get their first voice flow live within days, not months, and don't need in-house telephony expertise to do it.

Modern cloud voice platforms match or exceed traditional PBX reliability, provided they run on carrier-grade infrastructure with real-time monitoring and automatic failover. Zapim's network spans 100+ countries and handles thousands of simultaneous calls, with live call-quality monitoring (Voice Insights) and high-quality speech-to-text/text-to-speech to keep calls clear under peak load.

Use voice when SMS delivery is unreliable or the user can't receive texts, such as on feature phones, in poor-signal areas, or when an SMS OTP message goes undelivered. Zapim's Voice OTP reads the code aloud in clear, human-like audio, and can be triggered through the same Voice Call API you use for IVR and notifications.
