Is it possible to set different ringtones in Asterisk?

Question

Asterisk

1. Is it possible to launch an ivr-greeting in Asterisk when calling an external line, which does not require any action from the user and does not signal the operator to pick up the handset until the greeting is played?
2. Is it possible to set a different melody instead of a beep for different incoming subscribers by identifying it by number. For example, for 79001234567 we play one melody, for 79001111111 another?
I'm not so much interested in the implementation, but is it possible, then I'll continue to drip)
