I am a developer in the USA but have a potential partner in Belgium who wants to offer inbound voice agents to their Belgian customers. Ideally they want Flemish language, but will settle for Dutch if needed. Deepgram offers Flemish at https://developers.deepgram.com/docs/models-languages-overview so does that mean you can offer it also? Assuming the client is a small business such as a dentist, would I have them get a new Twilio number in Belgium to use with Vapi and then forward that Twilio number to their existing phone number? Are there any other complications because it is Flemish or Dutch and not English? Would calendar integrations be a problem?
