Currently, Vapi does not support Indian phone numbers—even on the Enterprise Plan—due to TRAI regulations requiring SIP termination via an Indian server, which Vapi does not offer. For US to US calls, the cost is
$0.05 per minute (Vapi fee) plus any underlying provider charges. International and India-to-India calling are not supported directly; for other countries, you can import numbers via Twilio or SIP, but rates will depend on your provider.
