@Angel Gochkov never port client numbers, its a nightmare. just buy a cheap twilio/vapi number to use as a hidden bridge. have the client set up "conditional call forwarding" (usually by dialing *71 or *92 + ur new number) on their actual phone. this way, if their human staff misses a call, the carrier auto-routes it to ur ai. clean, simple, and zero infrastructure risk.

@Angel Gochkov go to a global voip wholesaler like zadarma or telnyx. u can usually grab local eu numbers there for like 2 to 5 bucks a month. buy the cheap number there, and then just route the sip traffic directly into vapis sip uri. vapi accepts native inbound sip. saves u 100+ euros a month and keeps the exact same conditional forwarding logic.
