Hello, I also have a Synopsys and need the manual and/or software. I can not find the link to the manual as you stated "above". I click on manuals and none of those vendors seems to have the Synopsys. Please help. I have spent a ton of time on this. I have Lingo Activevoice voicemail and Telrad digital display phones. The system is up and running fine, but I need to reprogram a few things. thanks a ton!
