I have a customer who needs to have staff in the office join in on calls in progress occasionally. I programmed a button for them with Feature 83. This is supposed to allow them to turn off the privacy feature on a per call basis. They have reported that only 2 other people can jump in on the call when privacy is turned off, but more than 3 people cannot be on this call. This is not a Conference Call, so I am surprised to hear this. It seems that there would be no limit to how many could pick up when privacy is off. What say you??
