what would it take to add support for "message-summary" package?  i may
have time to help if you give pointers to places in code that need to be
modified.

in "message-summary" package, content type is

Content-Type: application/simple-message-summary

and body is just a few text line, such as

Messages-Waiting: yes
Message-Account: sip:alice at vmail.example.com
Voice-Message: 2/8 (0/2)
