Dear <@&1231325148079194222> could you please provide me with the instruction on how connect the local SIP number to VAPI but not through Twilio?

<@1123909312998277120>
Certainly! To connect a local SIP number to VAPI without using Twilio, you'll need to follow these general steps:

1. **SIP Domain Registration**: Register your SIP domain with a SIP provider that allows you to connect external SIP numbers.

2. **Configure SIP Endpoint**: Set up your SIP endpoint with the necessary credentials provided by your SIP provider. This typically includes the SIP URI, username, and password.

3. **Forwarding to VAPI**: In your VAPI application, when setting up the forwarding rules, use the `sipUri` attribute within the `forwardingPhoneNumbers` array to specify the destination SIP address. This will direct the calls to your local SIP number.

4. **SIP REFER Handling**: Ensure that your system is configured to handle SIP REFER messages, as VAPI uses SIP REFER to transfer calls.

5. **Testing**: After configuration, make sure to test the setup to ensure that calls are correctly routed to and from your local SIP number through VAPI.

If you need specific instructions or assistance with any of these steps, please provide more details about your current setup or the SIP provider you are using, and I'll be happy to help further!

Hey <@1123909312998277120> for local SIP numbers you have to first connect with your telephony provider and ask them about their current process and how do they support VOIP SIP Trunking. After getting the required information from your telephony provider we can only then proceed.

<@1123909312998277120> for the reference you can use the existing SIP docs, to collect the right information from the telephony provider.

I sent you direct message with the parameters of SIP and I need your guidance on what should I do in VAPI to connect this SIP\
