@ivan Absolutely, you can use your own Singapore phone number with VAPI. If you have a number from Twilio, you can easily integrate it with our services to place and receive calls. If you need assistance with setting up your phone number or have any specific questions about the process, please let me know, and I'd be happy to help!

ok may i know what is the process of me using my own singapore phone number ? as currently i only see the option of using twilio numbers

@ivan To use your own Singapore phone number with VAPI, you'll typically need to go through a process called number porting, which allows you to transfer your existing number from your current provider to Twilio, which is then used with VAPI. Here's a general outline of the process: 1. **Check Portability**: Verify that your Singapore phone number is eligible for porting to Twilio. 2. **Prepare Required Documentation**: Gather the necessary documents, which may include a Letter of Authorization (LOA), your most recent phone bill, and any additional information required by local regulations. 3. **Submit Porting Request**: Through Twilio's porting tool or support, submit your porting request along with the required documentation. 4. **Wait for Confirmation**: Twilio will work with your current provider to transfer the number. This process can take some time, and you'll be updated on the progress. 5. **Configure Number with VAPI**: Once ported, you can configure your Singapore number in your VAPI account to make and receive calls. Please note that the specifics can vary based on the regulations in Singapore and the policies of your current provider. It's best to check with Twilio's support for detailed instructions tailored to your situation. If you need further assistance or have more questions, feel free to ask!

@Vapi i am looking at twilio's website and they dont allow singapore phone number porting

@ivan I apologize for the confusion. If Twilio does not support porting of Singapore phone numbers, you would need to use a Twilio-provided number or consider alternative Voice API providers that support using Singapore numbers. As an alternative, you could: 1. **Use a Twilio Singapore Number**: Choose a Singapore number from Twilio's inventory to represent your business. 2. **Forward Calls**: Set up call forwarding from your existing Singapore number to the Twilio number. 3. **Caller ID**: Use Twilio's caller ID feature to display your existing Singapore number when making outbound calls, if this feature is supported in Singapore. If these options do not suit your needs, please reach out to VAPI support or explore other voice service providers that may offer the capability to use your own Singapore number directly. If you have any other questions or need further assistance, let me know!

@ivan To use your own phone numbers with Vapi, you need to check with your telephony provider if they support SIP trunking. If they do, then I will share the further process to set up SIP trunking using your telephony provider and Vapi.

hi @Shubham Bajaj , I am facing the same issue than ivan, my provider support SIP trunking, could you share the detailed process to set up SIP trunking using my telephone provider , thanks!!

@Ivan OU refer to the following guides that demonstrate how to establish a connection with your SIP provider: https://www.notion.so/SIP-be5179f856e046688c69eba817e7fcc3 https://www.notion.so/SIP-Inbound-Guide-1f0789ae62024748a62a6d81076b9f32 https://www.notion.so/SIP-Outbound-Guide-997d66df35284295b7149fc10c82f3e8 Note: While these guides use Twilio as an example, the process remains consistent across other telephony providers. Don't hesitate to reach out if you require additional assistance.
