i have entered byo SIP but now i want to change. second why it is giving me the option of vonage and twillio. I have my own sip and i want to use it. whta to do?

To change your BYO SIP settings in Vapi, you need to modify the

sipUri

attribute in your configuration. According to [Vapi documentation](https://discord.com/channels/1211482211119796234/1333747605628391434), you can update this by using the API endpoint:

POST https://api.vapi.ai/credential

Vonage and Twilio appear as options because Vapi integrates with them for phone number management, but you can still use your own SIP service by properly configuring the SIP URI with your provider's details.

Hey, you can follow this documentation on how to set up SIP using VAPI. It is pretty easy and straightforward. Give it a try, and let me know if you are blocked somewhere or require further help.
