Is it possible to custom the sip domain. I want to replace the sip.vapi.ai by a custom domain with my name. Thanks

Based on the information I found, while Vapi uses

sip.vapi.ai

as its default SIP domain, there are indications that custom SIP configurations might be possible. You can specify a custom SIP URI through the Vapi API as shown in this example:

curl --location 'https://api.vapi.ai/phone-number' \
  --header 'Authorization: Bearer your-vapi-private-api-key' \
  --header 'Content-Type: application/json' \
  --data-raw '{
   "provider": "vapi",
   "sipUri": "sip:username@your-custom-domain.com",
   "assistantId": "your-assistant-id"
  }'

For definitive confirmation and detailed instructions, I recommend contacting Vapi's support team directly. Sources: - [Discord conversation about custom SIP domain](https://discord.com/channels/1211482211119796234/1337383511329345588) - [Vapi SIP documentation](https://docs.vapi.ai/advanced/sip/telnyx)

By what should I replace the username in the custom sip uri ?

Currently vapi don't support customizing the SIP domain, but you can explore white-labeling or on-premise options for custom domains by contacting the sales team thanks

@Ali well... on VAPI itself that is not possible as far as I know, as the system is basing the inbound authentication of requests with the domain as part of it. However, if you add Cloudonix to your setup, and pass your inbound calls via Cloudonix, it will enable you to create as many domains as you want, point these using a CNAME (or A Record) to our border gateway, which will then route to VAPI according to any logic you require. If you want, please DM and I'll run you through the setup.
