What voicemail system are you using with your Partner R7.0? Partner Messaging? Partner Mail VS?
You use a Selector Code to point to the Announcement. "For our address and website, press 7", and Selector Code 7 plays Announcement 1.
If it is Partner Mail VS, there are only 2 announcements available. If it is Partner Messaging, there are 99 announcements available.
After an announcement plays, the caller must press 0 to transfer to the Operator, *8 and an extension number to transfer to an extension, and if they do nothing, the call disconnects.
If you are using Messaging, I would use submenus instead of announcements, because then you can have selector codes in the 1st submenu call other submenus or dial extensions without the *8 first. Also, if the caller doesn't dial anything, the call will follow the "Dial-0/timeout" option and go to the Operator or General Mailbox, or whatever you have set for the auto attendant.
