Our phone system sometimes gets voicemail calls that do not disconnect properly. Then they tie up a voicemail answering box and an incoming line. Is it possible to clear the busy line without restarting the entire system? A tech with the people we purchased the system from said to have the phone company add "automatic disconnect" to all our phone numbers but our phone company has no idea what they are talking about. Is there a way to tell the system to stop recording on a certain voicemail box? We have Electra Elite phones and an EliteMail VMS system. Thanks for your help.
