What must you build around a raw voice API?
The call pipeline is only one layer. A sellable agency product also needs authentication, client isolation, role controls, usage metering, a price book, credit enforcement, branded pages, support workflows and operational monitoring.
When does buying save engineering time?
Buy when the client values a functioning branded service more than provider-level architecture choices. Dvaarik already connects usage to partner credit, client allocation and reseller pricing so your team can focus on configuration and integrations.
When should a developer still build?
A custom stack is sensible for proprietary orchestration, a required provider or geography Dvaarik does not cover, unusual compliance architecture, or infrastructure ownership. That route also means owning uptime, vendor reconciliation and client billing logic.
How can existing systems send leads?
Post approved lead data to the generic lead-intake webhook or import a CSV, then use the configured agent workflow. Embed web voice on client sites. Treat CRM connectivity as a webhook integration unless a specific native connector is documented.
