there are options within Intuity that people like...
1. a variety of greetings (internal, external, busy, no answer, default, temp/holiday etc.)
2. ability to do broadcast VM from with your mail box, and you can build the lists from within the mailbox. This can be "overcome" using the broadcast feature within HG/VM in the IPO, but it requires that you build broadcast HGs containing the members desired, for each list, for each user that wants to do this... basically putting the work on the IPO programmer rather than the individual user to build their own dist list for broadcasdt messages.
Most customers I have that stick with Intuity, do it for the above two reasons, more particularly item 1.
