It can't be that complicated.
replyMy doctor's office phone manages "You are number two in the queue". Somewhere, maybe it was a previous doctor, added "and should expect to wait about 5 minutes".
Even in my internal company tech support line they play that "higher than expected call volumes" message, but their website also has counter on it that tells you just how many people are on hold and even when it is just one (me) it plays that message.
replyThe only ones I believe are the ones that tell you the estimated wait time or number ahead of you (most of which offer to call you back).
replyIt is funny to hear "our wait times are higher than average, your wait is estimated to be zero minutes".
Easy for that to be true: just set your expectations to zero.
replyAll call centers are actually located in Lake Wobegon, where all the call wait times are above average.
