[Freeswitch-users] Ringback tone

[Miha]

Hi,

I need one info regarding ringback tone.

How ISP are sending for numbers which are unavalible, "number is 
temporary unavalible"? I guess this is send in ringback tone? but how to 
achive that with FS as I must bridge to avalible user and set action 
application ringback to set ringback application?

I need to do this for unavalibe numbers, setting own ringbacktone, on 
the call should not be answerd as if the call is answered, it will be in 
billing.

thanks!

Miha
