VAPI supports bring-your-own (BYO) SIP trunking. I’m a beginner and not familiar with the process—could you walk me through, from scratch, a step-by-step guide to connect my SIP trunk number to VAPI?

Thanks for reaching out! To give you the most accurate step-by-step guide, could you please let me know which SIP provider you’re using for your UAE number (e.g., Telnyx, Plivo, Zadarma, Twilio, or a local UAE provider)?

@Dev You can't connect DU directly to VAPI, as they will not connect to a non-UAE IP address. However, you can connect your DU account to Cloudonix, via our UAE SBC and from there directly into VAPI. Please contact me for more information.
