i enable “direct dial” in ivr.
when the dialed extensions is busy , i want ivr play “busy, try another number” to caller instead of hanging up directly.
it seems a classic function but i am too stupid to find out how to do it in freepbx.
i guess maybe i can create ring-group for every extension, and put every ring-group in the ivr. since ring-group has failover destation, i can put “busy prompt” ivr to the failover destation.
are there better ways to implement this function?
thanks a lot for help!
