Hi , I am trying to build a usecase for Indian consumers. But seems like Twilio not providing indian number. I spoke to a few SIP trunk providers in India, they can provide the SIP channels but they are asking if Vapi has the IPBX setup or we have to provide it? Also, in your SIP notion guide, I don't see where I need to configure the username/password of the SIP trunk? I only see the gateways section.

You can pass the credential by setting the outboundAuthenticationPlan while setting up the credentials. Btw, which local telephony provider you are using to set this up? https://cdn.discordapp.com/attachments/1338421915483897856/1338426936187289600/image.png?ex=67ab0ab8&is=67a9b938&hm=6dc503acd5006213d4e178c08dca473f0c3b49d9eeb09d380c535f35072107d0&

hi sahi, i have a similar issue with my SIP trunk

Which provider you are using right now and what's the exact issue that you are facing?

Hi Sahil, I am still trying to understand the SIP flow. I spoke to a few SIP trunk providers like JIO/Airtel. Could you suggest a carrier in India which I can use to do the integration?

Hey Shank318, Please refer to the following guides that demonstrate how to establish a connection with your SIP provider. **Note**: While these guides use Twilio as an example, the process remains consistent across other telephony provider.s [https://vapi.notion.site/SIP-104008c8393f80feaeb7de8ca19565ed](https://vapi.notion.site/SIP-104008c8393f80feaeb7de8ca19565edPlease) [Please](https://vapi.notion.site/SIP-104008c8393f80feaeb7de8ca19565edPlease) don't hesitate to reach out if you require additional assistance.
