Hello, I want to setup my 12VoIP connection in 3CX v10. But that is likely never going to happen. Just like many, many other Betmax providers, they provide a Username, not a SIP or Phone number. But they probably thought that this kind of provider aren't important, so they removed support for letters in the Auth (External Number). No way to get it working. Conclusion: Betamax, VoIP Buster and many other providers won't work anymore... For ever perhaps? Please explain this decision.
