I believe I can help you with that. Cloudonix provides a simple streaming interface, which you can connect to Pipecat (identical to Twilio's) and connect Zadarma to Cloudonix. You get 2 weeks for free, and if your volume is low (under 500 calls a month), you aren't charged at all. Have a look here: https://developers.cloudonix.com/Documentation/voiceApplication/Verb/connect/stream And you can open a free account at https://cloudonix.com

Is the solution available for the public yet?

Well, to summarize the call I had with @Buri Ilter - The EU as a "telephony landscape" is complex. Each country has its own set of regulations and KYC requirements. However, some companies can make the entire experience relatively simple to handle, specifically from the KYC perspective. Here are a few companies I like using for this type of service: DIDWW (www.didww.net) Will provide access numbers and termination services in various countries, while you can maintain multiple KYC documents under a single account. Setup of the account is "far from simple", in fact, I can find it complex at times - as it is a very much engineering oriented tool. You can obtain outbound calling from them as well - however, the service is pricey. If you need numbers in Italy, France, Germany, Greece, etc - this is the way to go. Account activation may require a few days to complete. DIDLogic (www.didlogic.com) Similar to DIDWW - but not as feature rich from my perspective. Pricing isn't bad and outbound services are also available. Account activation may require a few days to complete. DIDX (www.didx.net) Welcome to the wild-wild-west of telephony. DIDX is a Pakistani platform that has been around for over 20 years, and enables private "sellers" to sell their phone number over the DIDX exchange. The numbers are sourced via the platform, and you can find phone numbers from multiple countries and cities, with varying prices - however, the actual source of the number, in most cases, is unknown. This means, the numbers may be here today, and gone tomorrow - so, when you buy a number, pay attention to the information that is provided with it. They also have their own numbering ranges and repository, so use caution when buying one. To make life easy with the various AI platforms, I recommend connecting these via Cloudonix's platform. Why? simple - it will protect your AI Agent from "unwanted" calls and various other "bad actors" (true in general). When you buy a phone number, the number ranges are public information, which means, it is easy for a bad actor to "flood" your AI with calls. Connecting via Cloudonix provides a layer of "call-logic" before the AI agent, which you can use to "gate" your Voice Agent.

Dude, this is INSANE! When do you plan to release it? I'm dying to get my hands on it and play.
