IVM as announce only message "server"

[ebemis]

I am trying hard to understand and read the vast majority of previous posts to find this out:

In my "museum" when viewing an exhibit, a visitor can call up, key in the 2 digit code, and hear a message about the exhibit. Will IVM work for this, or is it overkill. I do not need, or want, any messages to be left by the callers, just for them to hear the informational recording.

 

This leads me to a specific question:

The IVM Telephone Attendant Small Interactive System allows up to 70 OGM menus and 8 voice mailboxes.

IVM Telephone Attendant Professional allows up to 70 OGM menus and 30 voice mailboxes.

In the case of Professional would I be allowed 70 different messages (announcements) to be played, or only 30?

Thank you all in advance for your help,

Ed
