Frequently Asked Questions

How does Voximplant Voice AI pricing work when I use an external LLM?

Voximplant charges separately for realtime audio connectivity, telephony or SIP connectivity, and optional speech-to-text, text-to-speech, or turn-detection services when those are provided outside the realtime AI system. You also pay the external AI provider directly for its API usage. Check the current Voximplant rate card and each provider's pricing for the exact workflow you plan to run.

Can I connect Voximplant to an existing PBX or SIP trunk?

Yes. Voximplant documents SIP trunking that bridges an existing PBX with the Voximplant cloud, allowing you to add call routing, IVRs, voicebots, or contact-center workflows. Supported codecs, encryption settings, allowed IP addresses, destination coverage, and usage rates should be checked against your configuration.

What security settings should I configure before connecting a SIP trunk to Voximplant?

Voximplant's SIP setup guidance calls for allowlisting the IP addresses or networks permitted to place calls when SIP authorization is not used, then routing calls through an application rule and VoxEngine scenario. Its SIP trunking materials also document SIP TLS and media-encryption options. Apply the settings appropriate to your network and confirm the current security guidance before production use.

How long does Voximplant keep call recordings, and can I choose the storage location?

Voximplant recording settings let you choose an expiration period, with documented options ranging from three or six months to one, two, or three years. Recordings can be saved in Voximplant cloud storage or in your own S3-compatible storage. Confirm the recording method and its applicable settings because retention behavior can vary by API or recorder.

What happens if my Voximplant account balance reaches zero during a call?

Voximplant says a call that is already active when the balance reaches zero may continue and create a negative balance. Services resume after the account is topped up. The platform also documents low-balance email alerts and configurable automatic top-ups through support.

Can Voximplant Kit connect call records and customer context to my CRM?

Voximplant Kit documents CRM and web-service connectors, including Zendesk, Salesforce, HubSpot, Bitrix24, and Kommo. The documented Zendesk integration can open matching contact records, create tickets after inbound calls, and log call details or update tickets. Capabilities and setup requirements differ by connector, so verify the specific integration you need.

How does Voximplant use voice recordings, prompts, and other AI inputs?

Voximplant's AI Tools Policy grants Voximplant and third-party providers a perpetual, irrevocable license to use submitted inputs to provide and improve services and develop new services or products. It also says third-party providers may retain inputs and outputs for moderation, auditing, debugging, or model improvement under their own policies. The reviewed public terms do not clearly establish a general opt-out or explain how deletion requests affect already licensed uses, so review the selected provider's terms before sending sensitive voice data or transcripts.

Is Voximplant suitable if I want a no-code contact center instead of building telephony APIs?

Voximplant Kit is the ready-to-use contact-center product, with a visual workflow builder, agent workspace, calling and messaging channels, and CRM context. The core Voximplant platform is more developer-oriented and exposes SDKs, APIs, and JavaScript-based VoxEngine scenarios. Kit pricing is quote-based and separate from the core platform's usage rate card.

How should I compare Voximplant with Twilio or Vonage for a programmable voice project?

Compare the same countries, call directions, phone-number types, expected minutes, messaging, recording, and AI-provider usage rather than comparing a single headline rate. Voximplant offers cloud-hosted JavaScript call scenarios and a separate Voximplant Kit contact-center product, while Twilio and Vonage have their own programmable communications ecosystems. The better fit depends on required APIs, architecture, integrations, support terms, and total usage cost.
