If you want local phone numbers for a Voice API, the usual options are:

  1. Buy/provision local numbers through your voice provider

    • Common providers: Twilio, Plivo, Vonage, Telnyx, Sinch
    • You can search by country, area code, city, and sometimes number type:
      • local
      • mobile
      • toll-free
      • national

  2. Use those numbers with the Voice API

    • Inbound calls: route to your webhook/app
    • Outbound calls: place calls from that local caller ID

  3. Check country availability

    • Not every country supports local numbers or voice features
    • Some require regulatory documents / address verification / business registration

Example with Twilio:

  • Search available local numbers
  • Purchase one
  • Attach it to a webhook for inbound calls
  • Use it as the caller ID for outbound calls

Example flow:

  • GET /AvailablePhoneNumbers/{Country}/Local
  • POST /IncomingPhoneNumbers
  • Configure voice webhook URL

If you want, I can give you:

  • a provider comparison
  • sample code for Twilio/Plivo/Vonage
  • or help you find local numbers for a specific country/city
