I'd have to disagree with this. I have worked for 2 Fortune 500 companies for 35 years and all the CC calls were allowed questions from those attending as well as ones that were in advanced. The reason is to engage the people on the call so their actual concerns can be heard and answered and they feel like they are being listened to as well as the interaction. It's the interaction that is important. It makes it personal and let's everyone know the company is 'in touch'.

The reality is no one will be totally happy, but what needs to be done is to outline the details. If the company knows what needs to be done, you outline them. People can complain about the wait all they want, but if the details are outlined, the wait is the wait.
