Recently our company has been having an issue with certain phone calls. Mostly conference calls. There will usually be one user that goes silent during the conversation. Meaning his audio drops off. He usually doesn't know this and keeps talking. When they come back they are in mid sentence. This happens sometimes for 5 seconds and sometimes doesn't come back at all making the user have to hang up the call and redial. Not sure what information is needed for this. Most of the conference calls are on a software bridge. We have recently setup a hardware bridge but not totally in use yet.
