Theres the SMS method that other people have mention...
There are other methods if you are the Cellular Provider for say a CoOp or a rural ilec... These include (but not limited too and depend on your switch) SS7 TCAP MWI message, sending the correct DTMF down the loop to the switch, etc etc...
That being said its posible to use freeswitch for this... It just depends on exactly what type of interconnect you are doing

When you say wireless do you mean like Cellular Phone?

Hi, I'm trying to use FreeSWITCH's mod_voicemail to replace the voicemail on
wireless phones. Does anybody know how to make the wireless phone know there
is a voicemail waiting, so it can notify the user?
Thanks for the help!
