Hi @Shubham Bajaj I am trying to make outbound call using VAPI and Plivo (I have purchased indian number and destination number is also indian) { "id": "0f1c1751-c734-424f-89ef-15200963ba9a", "assistantId": "52739d19-cdce-4903-8563-a1476d2d0d39", "phoneNumberId": "ba4e0f4e-fe1e-444d-b715-638e71703230", "type": "outboundPhoneCall", "createdAt": "2025-05-06T02:59:39.799Z", "updatedAt": "2025-05-06T02:59:39.799Z", "orgId": "a55e28be-be19-4ff3-bb9a-d2aae6511e42", "cost": 0, "customer": { "number": "+917814064561", "numberE164CheckEnabled": false }, "status": "queued", "phoneCallProvider": "vapi", "phoneCallProviderId": "141cb4ce-a6ba-4071-b639-f0fce8089f01", "phoneCallTransport": "pstn", "phoneCallProviderDetails": { "sbcCallId": "fe45f893-a4c8-123e-4fbb-06496812ecbf" }, "monitor": { "listenUrl": "wss://phone-call-websocket.aws-us-west-2-backend-production2.vapi.ai/0f1c1751-c734-424f-89ef-15200963ba9a/listen", "controlUrl": "https://phone-call-websocket.aws-us-west-2-backend-production2.vapi.ai/0f1c1751-c734-424f-89ef-15200963ba9a/control" } } here is the response of call/phone api endpoint. getting this error An error occurred in this call: call.in-progress.error-sip-telephony-provider-failed-to-connect-call Please help

The error you're seeing is likely due to geographic restrictions. According to the information I found, VAPI numbers are currently only permitted to make calls to US-based numbers, even for free telephony. **Solution**: Use SIP trunking to connect your Indian numbers. Check with Plivo if they support SIP trunking with VAPI, then configure the SIP trunk with proper authentication details:

json
{
  "provider": "byo-sip-trunk",
  "name": "Plivo Trunk",
  "credentials": {
    "username": "YourPlivoUsername",
    "password": "YourPlivoPassword"
  }
}

Plivo support trunking on indian number also https://www.plivo.com/docs/voice/ai-voice-agents/how-to-integrate-plivo-with-vapi#step-3-make-outbound-calls-from-vapi here's outbound calling setup

Waited 300s But Transport Never Connected. Hey as you can check in the screenshot your Pilvo is rejecting the outbound call, you need to check with them for further details. https://cdn.discordapp.com/attachments/1369153190326439956/1369445297796681948/callid-fe47a879-a4c8-123e-d69a-0ec7040a32ad.pcap?ex=681be2d2&is=681a9152&hm=7318acabc79400f25fc0df8ce91327785b22f9290398d685472c87c65f0de4d1& https://cdn.discordapp.com/attachments/1369153190326439956/1369445298237079572/image.png?ex=681be2d2&is=681a9152&hm=a472b38193eef4cc6e7ed786c79267d76313c8a61f7bdc8700ad2ebc770841fa&

@User Can you please tell me any other alternative for this?

You can use a Viva Digital. They provide Indian phone numbers and then through SIP trunking you can directly connect them to VAPI.

Yes I need help

Have you looked into Exotel? You can also use that provider as well.
