Monthly usage model
Assumptions
- US/Canada domestic business calling unless a provider source says otherwise.
- Taxes, regulatory recovery fees, E911, TCR messaging registration, premium numbers, international rates, and hardware purchases are excluded unless listed as hidden-cost flags.
- UCaaS plans are modeled as per-user subscriptions with domestic calling included or fair-use governed. SIP providers are modeled by numbers, channels, and minutes.
- AI agent minutes are only priced when the provider publishes a native AI voice-agent rate or a source gives a clear planning unit. External voice-agent platform costs should be modeled separately.

FAQ
FAQ
VoIP cost calculator questions
Why do UCaaS and SIP providers price VoIP differently?
UCaaS providers usually bundle seats, apps, and domestic calling into a subscription. SIP and carrier providers usually price numbers, inbound minutes, outbound minutes, toll-free usage, channels, and routing separately.
Does the calculator include taxes and regulatory fees?
No. The calculator is a planning estimate. Vendor taxes, regulatory recovery fees, E911, toll-free surcharges, messaging registration, hardware, and international rates should be verified with the provider quote.
How should I estimate AI voice-agent cost?
Use published native AI voice-agent pricing when available. If the provider does not publish a native rate, estimate AI platform, speech-to-text, text-to-speech, LLM, orchestration, and call recording costs separately.
