Find the right call workflow.
Compare the same phone call
One example: a 45-second managed phone call
Assume the Omni session and the connected managed call each last exactly 45 seconds. This illustration excludes taxes, number fees and other services; actual metered durations may differ.
- Omni speech and reasoning: $0.05/min × 45/60 = $0.0375.
- Managed telephony: $0.01/min × one one-minute pulse = $0.0100.
- Illustrative total for those two line items: $0.0475.
To compare another provider, use the same connected time, features, region and model. Include its voice, model, telephony, subscriptions, minimums and rounding rules. Prices and terms change.
Choose the operating model
Omni combines speech and reasoning in a managed runtime, with optional managed telephony. Platforms such as Vapi and Retell provide configurable voice-agent workflows; Bland offers managed calling plans. The right choice depends on which components, models and phone operations your team wants to own.

Frequently asked questions
How should I compare voice agent platforms?
Test the same caller tasks, interruption cases, languages, tools, handoffs and telephony path. Compare completed outcomes and operations as well as latency and cost.
How do I compare phone call costs?
Include the voice session, model, telephony, add-ons and any subscription. Use the same duration, region and billing increments, and consult each provider's current terms.
When does a configurable platform fit better?
A configurable platform can fit when selecting individual models or owning specific components matters. A managed runtime can reduce the integration work your team owns.
How fast is Omni?
A PyAI in-region early measurement found about 390 ms median voice-to-voice latency; it is not an SLA or a controlled head-to-head result. Test each option under the same conditions.
