Hello!
Currently, VAPI supports the direct purchase of US & Canada phone numbers. For phone numbers in other regions, such as the UAE, you would need to import them. However, as you've mentioned, if Twilio and Vonage do not offer UAE numbers for outbound calls, it would not be possible to purchase or port a UAE number through these providers into VAPI at this time.
If you require a UAE number for your voice applications, I recommend reaching out to Twilio and Vonage support directly to inquire about any potential options or future availability. They may have solutions or workarounds that are not publicly listed.
Please let me know if there's anything else I can assist you with!
