Production voice agents need two kinds of expertise. Plivo has both.
Agent orchestration makes it sound human. Telephony makes sure customers hear it.
Vapi brings orchestration expertise only. Plivo brings both.
Two layers. Two kinds of expertise.
Both platforms cover both layers. The difference is depth.
Agent Pipeline
Everything that shapes how the conversation sounds.
- Speech-to-text, LLM orchestration and text-to-speech
- Turn-taking, endpointing, interruption handling and back-channeling
- Prompts, tool calls and system integrations

Telephony
Everything that gets the call answered in the first place.
- Branded caller ID, CNAM, FCR and caller reputation registration
- Outbound campaigns at scale, TCPA compliant
- Sustained concurrency without answer rates dropping with scale

What our customers say
“We chose Plivo for the voice layer: calls route where we need them, at a good price and very low latency. We don't see the drops we had before.”

Frequently asked questions
Both give you agent orchestration and phone numbers. The difference is where the expertise sits. Vapi's is orchestration, and you pick and pay the telephony, speech and LLM providers separately. Plivo builds and runs both the orchestration and the telephony, so your agent and the calls it makes come from one team, on one all-inclusive $0.04/min rate.
$0.04 per minute, everything included: telephony, voice models, transcription, and orchestration. No monthly platform fee. Volume discounts through sales.
That is decided at the carrier layer, not in your agent, so no prompt or setting fixes it. Your number needs a CNAM record, registration with the AT&T, T-Mobile and Verizon reputation programs, and a Free Caller Registry submission. Plivo runs all of that for you, and branded calling puts your business name and logo on the caller ID.
The FCC treats an AI voice as artificial or prerecorded, so marketing calls generally need prior express written consent, not just a number from a form fill. Plivo is the carrier in your call path, so attestation and blocked-call remediation sit with us rather than a third party. General information, not legal advice.
Yes. Describe the agent in plain English and Vibe Agent builds the flow in AI Agent Studio. Prefer code? Build it with our APIs and SDKs instead.
Under 500ms, voice to voice. We run telephony, speech and orchestration ourselves rather than relaying between vendors, so there are fewer hops in the audio path.
Concurrency and calls per second scale with your usage, at no extra charge. Vapi's Build plan includes 10 concurrent lines and charges $10 per extra line per month.
Rebuild your agent logic in AI Agent Studio or via the API, then run both platforms on the same calls. Move a slice of traffic first, watch task completion and transfer success, then shift the rest and port your numbers. Porting is free for US and Canada numbers.
Agent orchestration and telephony, from one team
No setup fees, no vendor lock-in, one predictable agent rate.
