IIUC, FreeSWITCH does not generate the dialtone.  The VoIP phone will do
that itself, and an ATA will generate it for a analog (POTS) phone.  Your
message wasn't clear if you are using VoIP phones, or an ATA (analog
telephone adapter) with analog phones.  A VoIP phone will "subscribe" with
FreeSWITCH to a MWI login, and FreeSWITCH will send it a message whenever
the number of messages waiting changes.  In response, the VoIP phone will
light the MWI and will play a stuttering dialtone when the handset is
picked up.

According to http://www.voip-info.org/wiki/view/MWI "...most
ATA<http://www.voip-info.org/wiki/view/ATA>'s
support stutter dial-tone."
