asterisk users - Jul 2014 - Send fax when asterisk is callee legs

Hello,
I have a simple ivr, In one submenu (such as 9), i want to send a fax.
so anybody call with server and then press 9 dtmf . should send a fax.
How can asterisk send fax for current channel? I use SendFax()
function in dialplan but when the application is run, the Asterisk CLI
closed and dont send fax.
I could send fax if asterisk works as caller legs but dont send fax if
asterisk was callee.How can i solve this problems?
With Regards.Mojtaba
