The fsk buffer seems to be sent when calling send_caller_id(), which is called from ZAP_CHANNEL_STATE_CALLWAITING. In any case, there is not much places where the modulated signal can be sent, everything goes down the file descriptor of the channel via zap_channel_write(). As I said, is done through send_caller_id() -> zap_channel_send_fsk_data() which sets the write function pointer to zchan_fsk_write_sample() and is then called back when calling zap_fsk_modulator_send_all(). May be you should take a look at src/testcid.c to learn about the API usage and src/zap_callerid.c to see the implementation. -- Moises Silva Senior Software Engineer Sangoma Technologies Inc. | 50 McIntosh Drive, Suite 120, Markham ON L3R 9T3 Canada t. 1 905 474 1990 x 128 | e. m...@sangoma.com
