Hi please could you suggest which is best platform to integrate indian phone numbers to vapi I have used zadarma it's not at all working Why so much complicated to integrate indian phone number ?

Hi makemyflights | Ø,G, Integrating Indian phone numbers with Vapi can be challenging due to TRAI regulations, which require using local telephony providers. For successful integration, consider using a provider like [Exotel](https://www.exotel.com/) or [Viva Digitally](https://vivadigitally.com/) as they offer Indian SIP trunking services. You can then follow the integration steps in the [SIP Trunking Guide](https://docs.vapi.ai/advanced/sip/sip-trunk) on our documentation. It typically involves setting up a SIP trunk to connect your provider with Vapi.
