Voicemail message information


I am looking for some suggestions regarding voicemail solution. Actually i am remotely connecting my asterisk servers to get voicemail messages information by using AMI. i am using MailboxCount to get box information, but now i also need to know when the message is left , kind of all the information that is already written in the .txt file of the voicemail message. Is there any way i can get that information by using AMI?
