Anybody out there ever use one of these types of phones? I can't get the MWI working. I can get it to work on other analog phones. I've found the documentation for this phone and it has a switch on the back of the phone for different types of MWI. I've tried all of the settings and have even been in touch with their tech support. I know it's a shot in the dark, but I just wanted to put it out there to see if anyone has any experience with this type of phone. Thanks in advnance for any advice.
