Is there any way to get more information into the email that has the voicemail attached? In particular I'd like the number of the sender in addition to the description. This would be fine in the Subject or in the Body of the message. Thanks.

The ANI information is included in the subject line in later versions of Unity 4.x and in the 4.2(1) release you can customize the subject line contents which can include, among other things, the ANI as you like it.
For 4.0(4) you cannot edit the subject line content, you'll have to get to a newer version.
