I upgraded my V10 3CX to V11 today but soon I run into problems. Trying to build a new voice prompt set for the digital receptionist, I realized that 3CX won't ring my extension to play the prompts, nor it rings my extension to record a new prompt. I get the error "Unable to perform the operation. Please try again" Related to that I also realized that initiating a call from MyPhone does not work either. No error message this time, though. It simply doesn't work. When receiving calls on my extension, MyPhone works fine meaning it senses the call and shows that in the interface. Does anybody have a solution for that? Thanks.
