I see that the 3CX phone supports multiple accounts and I have added a few. But it looks like it only supports ONE at a time, which makes it unusable for my purposes. I have several phone number and businesses that I have accounts for and I could receive a call at any time from any of them. The IP phones support multiple accounts and I have those configured fine with 3cx server... They can receive/send calls from any account at any time. Am I missing something here?
