Any recommendations to buy European phone numbers? I am from Spain so if I want to use Voice Agents through phone calls I would get charged for international calls unless the numbers are spanish (both European and US numbers). I have tried purchasing spanish phone numbers in different providers and the experience is horrible. Some of them like Twilio or Plivo don't even offer Spanish phone numbers. Telnyx does offer them but you have to go through a painful approval process that requires you to be a registered business and provide a lot of documentation. Do you know any better alternative to be able to call Pipecat agents through a phone number and not get charged international call fees?
