I'm a new user and I'm very excited to be building with Vapi. I have successfully set up my entire workflow in n8n to make outbound AI calls, and I'm on the final step of configuring the phone number and voice. My project has two very specific requirements: I need to make outbound calls to Indian phone numbers. My AI agent must speak in a high-quality Gujarati voice for my local clients. I have run into some roadblocks with the telephony providers. I've discovered that Twilio is not currently offering local Indian numbers for new accounts, and I've also had technical trouble with the Vonage sign-up process. Could you please provide some guidance? 1. Indian Number Provider: What is the official, recommended telephony provider (like Twilio, Vonage, Exotel, etc.) that you know works best and most reliably for purchasing and importing Indian phone numbers to use with Vapi? 2. Gujarati Voice: I also noticed that there are no built-in Gujarati voices. What is the best external TTS provider (like Azure, Google) to connect to Vapi to get the most natural-sounding Gujarati voice? Thank you so much for your help! I'm really looking forward to getting this project launched.

Regarding outbound calls to Indian numbers: According to the documentation, Indian phone numbers cannot be used with Plivo on Vapi due to TRAI regulations, and there is no official recommendation for another provider that supports Indian numbers with Vapi at this time. If you have access to a Twilio or other SIP provider account with existing Indian numbers, you may attempt to import them, but new purchases are not supported. If you need to proceed, consider reaching out to local providers directly for SIP trunking options, but note that Vapi currently does not support SIP termination via Indian servers, which is required by TRAI. [See details in the Vapi Plivo SIP integration guide.](https://docs.vapi.ai/advanced/sip/plivo) Source: - [Plivo SIP Integration](https://docs.vapi.ai/advanced/sip/plivo)

You will need to get in touch with ([huzefa@vivadigitally.com](huzefa@vivadigitally.com)) [vivadigitally.com](http://vivadigitally.com), or any other telephony provider that offers a SIP trunk. They will be able to help with the number, and then you can read this guide about integrating it. Note: This guide uses the Twilio SIP trunk as an example, but the procedure is pretty much the same for other telephony providers as well.
