Hi, My Requirement: I want to use my company's existing Canadian business phone number when making outbound calls through Vapi I need customers to see our real local Canadian number as the caller ID, not a US number or third-party provider number I prefer not to use Twilio or transfer our number to another provider if possible My Questions: Is there a way to use our existing company phone number directly with Vapi without moving it to Twilio? Do VAPI support SIP trunking or other integrations that would allow us to keep our current phone provider while using Vapi's voice AI capabilities? Are there any alternative solutions for Canadian businesses that want to maintain their existing phone infrastructure? I'd appreciate any guidance on the best approach for our use case or if there are enterprise solutions that might address this requirement.
