No platform fee, no seat licences, no minimum. ## Languages US callers use Many US phone lines take calls in English and Spanish, and a good share of callers move between the two inside one conversation. A CallWhiz AI agent decides the language of each reply turn by turn, so a caller who opens in English and continues in Spanish is followed rather than transferred. Accents are kept within a language: Mexican Spanish is not flattened into European Spanish, and US English is not treated as British. Numbers, dates, ZIP codes and dollar amounts are read the way a person says them aloud, and important ones are read back for confirmation. ## Phone lines and numbers in the US The agent connects over SIP to the phone system you already run, cloud or on-premise, so you keep your numbers, your carrier and your rates. If you would rather take a number from CallWhiz AI, numbers are available in 20+ countries and calls can reach destinations in 180+. Routing is per number: a practice can put its main line on the agent while the back line stays as it is. Inbound and outbound come from the same agent, so a receptionist line and a follow-up campaign are one build, not two. ## Rules that matter for calling in the US Outbound calling in the US turns on consent. The Telephone Consumer Protection Act (TCPA) governs automated and prerecorded calls to mobile numbers, US regulators treat AI-generated voice calls as robocalls under it, and the National Do Not Call Registry applies to marketing calls. Call-recording consent is set by state law, and some states require every party on the call to consent. CallWhiz AI does not decide whether your list has consent; that stays with you. What it does is enforce its side of the rules as settings on the agent rather than instructions in a prompt: - A switch that makes the agent state it is an AI before it starts. - Calling hours per agent, in the customer's own time zone, enforced before a call is placed. - A daily cap per number, so nobody is called repeatedly by accident. - Opt-outs honoured the moment a caller asks, and recorded as such. - Long numbers and one-time codes masked in speech; identity required before any account detail is discussed. - Ready-made policy packs for regulated work, with the stricter rules locked on rather than left to configuration. This is general orientation, not legal advice. Rules change; check the current ones with your counsel before you launch. ## Where call audio and records can live The hosted service is the fastest start. When call audio has to stay within your own boundary, the same platform runs inside your own AWS, Azure or GCP account in a US region, or on your own hardware for networks with no cloud at all. Retention and erasure run on your schedule, and a caller's data can be erased on request. In-cloud and on-premise deployments are scoped first, then live on real calls in about 30 days. ## What teams in the United States build first - [AI receptionist that answers every call](https://callwhiz.ai/solutions/ai-receptionist.md): A US front desk takes calls in English and Spanish; the agent answers in whichever the caller uses, books against the calendar in the caller's time zone, and states that it is an AI when you switch that on. - [AI phone agent for inbound and outbound calls](https://callwhiz.ai/solutions/ai-phone-agent.md): Inbound and outbound from one agent on US lines, with the controls consent-based outbound calling under the TCPA relies on: calling hours in the customer's time zone, a daily cap per number, and opt-outs honoured the moment a caller asks. - [Voice AI platform for building phone agents](https://callwhiz.ai/solutions/voice-ai-platform.md): Self-serve signup, credits priced in US dollars, and the same platform available inside your own AWS, Azure or GCP account when call audio has to stay within your boundary. - [Conversational IVR replacement: route by what callers say](https://callwhiz.ai/solutions/ivr-replacement.md): Replace a press-one menu on a US line with an agent that routes by what the caller says, in English or Spanish, while your carrier and numbers stay exactly as they are. - [AI outbound calling for sales follow-ups and collections](https://callwhiz.ai/solutions/ai-outbound-calling.md): Outbound campaigns to US numbers run with the controls TCPA compliance relies on: calling hours in the customer's time zone, a daily cap per number, and opt-outs honoured during the call. The list, and the consent behind it, stays yours. - [AI appointment booking, rescheduling and reminders by phone](https://callwhiz.ai/solutions/ai-appointment-booking.md): Books, reschedules and cancels against a real calendar across US time zones, in English or Spanish, and confirms the date and time by reading them back the way a person says them. - [Multilingual voice agent: 30+ languages, one agent](https://callwhiz.ai/solutions/multilingual-voice-agent.md): English and Spanish from one agent, following a caller who switches mid-sentence, with accents such as Mexican Spanish kept rather than flattened. - [AI customer support over the phone, from your own material](https://callwhiz.ai/solutions/ai-phone-support.md): Support calls answered from your own material in English or Spanish, with identity required before any account detail and long numbers masked in speech, on your existing US lines. ## Questions **Which countries does CallWhiz AI serve?** CallWhiz AI serves teams in the United States, the United Kingdom, Europe, the Middle East and India, with call destinations in 180+ countries and numbers available in 20+. Each market has its own page covering the languages callers use, how phone lines connect, where call data can live and the calling rules the agent's controls are built for. **Which time zone do calling hours use?** The customer's own. Calling hours are set per agent and enforced before a call is placed, so a campaign that spans several countries or time zones never rings anyone outside the window you set. A daily cap per number applies as well, and opt-outs are honoured the moment a caller asks. **Can I get a local phone number in my country?** Numbers from CallWhiz AI are available in 20+ countries, and calls can reach destinations in 180+. Where a local number needs registration paperwork, or where the telecom rules require a licensed local carrier, connect your existing lines over SIP instead and keep your numbers, your carrier and your rates. **Can call data stay in my country or region?** Yes. The same platform runs inside your own AWS, Azure or GCP account in the region you choose, so call audio never leaves your boundary, or on your own hardware for networks with no cloud at all. Data residency by region is available on the hosted service when you need it, and retention and erasure run on your schedule. **Does the agent tell callers it is an AI?** A CallWhiz AI agent can be set to state that it is an AI before it starts, with a single switch on the agent. The guard that enforces rules like this sits between the model and the voice, so a breach is stopped before it is spoken rather than flagged afterwards. **Is pricing different by country?** Credits are priced in US dollars wherever you are. One credit is US$0.01; a standard-voice minute is about five credits, premium voices about seven, realtime models eight to fifteen. No platform fee, no seat licences, no minimum, and larger deployments are quoted separately.
