Good day. I was running through the DAA example of C5402 DSK. When DAA detects two ring tone, the phone goes off-hook. However, after the caller hung up, the phone does not go on-hook. I like to implement a busy tone detect routine, set the phone on-hook and restart the wait for ring tone. Anyone like to share their experience with asm or C code for busy tone detect? The busy/disconnect tone in my country is at 425Hz with even on-off interval of 750ms. This DSK provides DAA APIs for ring detect, off-hook, on-hook functions etc. However, there is no clue on how these functions works(like a black box). Thank you for your time and attention.
