Hi @Vapi, @Vapi Ticket Bot and @Shubham Bajaj @Sahil Could you please assist with setting up VAPI outbound and inbound calls with Exotel? I spoke with them, and they confirmed that they provide streaming for inbound calls, but not for outbound calls. We also need to set up an Indian phone number for testing. Any guidance on how to navigate this situation or suggestions for alternative services we could contact would be greatly appreciated. Thank you!

Hi there! 👋 I'd be happy to help you set up VAPI with Exotel for both outbound and inbound calls, as well as provide options for obtaining an Indian phone number. ## Setting Up Outbound Calls with Exotel Since Exotel doesn't support streaming for outbound calls, you'll need to configure a SIP trunk: 1. **Set up the SIP Trunk with Exotel**: - Configure a SIP trunk in your Exotel account to connect to VAPI - Make sure to set up the correct authentication parameters (username, password, IP address, and port number - typically 5060 for UDP) 2. **Configure VAPI**: - Create a new SIP trunk in VAPI with this structure:

json
   {
     "provider": "byo-sip-trunk",
     "name": "Exotel Trunk",
     "gateways": [
       {
         "ip": "Exotel_IP_Address",
         "port": "5060",
         "netmask": 32,
         "inboundEnabled": true,
         "outboundEnabled": true,
         "outboundProtocol": "udp"
       }
     ]
   }

- Send this configuration to the API endpoint using:

bash
   curl -X POST 'https://api.vapi.ai/credential' \
   -H 'Authorization: Bearer YOUR_API_KEY' \
   -H 'Content-Type: application/json' \
   --data-raw '{ /* JSON structure shown above */ }'

3. Configure your dial plan in Exotel to route calls through the VAPI SIP trunk ## Setting Up Inbound Call Streaming with Exotel 1. **Configure SIP Trunking on Exotel**: - Create a new SIP trunk in your Exotel account for handling inbound calls - Gather details like SIP URI and authentication credentials 2. **Configure VAPI**: - Add your SIP trunk details under the forwardingPhoneNumbers attribute:

json
   {
     "forwardingPhoneNumbers": [
       {
         "sipUri": "sip:your-exotel-number@sip.exotel.com"
       }
     ]
   }

3. Create a VAPI assistant to handle incoming calls 4. Test the setup to ensure calls to your Exotel number are correctly routed to your VAPI assistant ## Obtaining an Indian Phone Number for Testing

Anybody from VAPI can you please confirm if anyone was succesfull with the above setup guide .

Hey @EinNot , where you able to figure out a proper solution to this? I was also looking to integrate Vapi or Retell with Exotel... Not yet found a proper solution to this... Still researching...
