Reading Caller.Digital's Price Breakdown
Caller.Digital deserves credit for publishing a line-by-line rate: phone carrier, infrastructure, LiveKit infrastructure, support and a platform fee, plus speech-to-text, LLM and text-to-speech on its Growth plan. On pay-as-you-go the AI model lines are blank because you bring your own keys, so your model bills come on top of ₹9.42.
Vistara AI rolls the same components into one rate: ₹3.00 per connected minute on pay-as-you-go and ₹2.00 on Platform Growth, with no minimum on pay-as-you-go.
The Verdict: When to Pick Caller.Digital, and When to Pick Vistara AI
Choose Caller.Digital if you already hold your own AI model contracts and want an Indian calling layer around them, or if its specific integrations fit your stack.
Choose Vistara AI if you want the lower published all-in rate (₹2.00–₹3.00 per connected minute) with AI models and telephony included and no volume minimum.
