Hello, I am writing my own freeswitch module and have implemented 2 hooks for reading and writing audio (I did not implement the endpoint interface). My problem is that the channel_write_frame and channel_read_frame callback-functions are only called if I make an intercept with another session (switch_ivr_intercept_session), but my usecase has only one single Session for getting and putting audio data in my module. How can I achieve this? scaram /* on channel init I answer the session and set hooks */ static switch_status_t channel_on_init(switch_core_session_t *session) { switch_channel_t *channel = switch_core_session_get_channel(session); switch_channel_answer(channel); switch_channel_set_state(channel, CS_EXCHANGE_MEDIA); switch_set_flag(tech_pvt, TFLAG_IO); switch_core_event_hook_add_write_frame(session, &channel_write_frame); switch_core_event_hook_add_read_frame(session, &channel_read_frame); } static switch_status_t channel_write_frame(switch_core_session_t *session, switch_frame_t *frame, switch_io_flag_t flags, int stream_id) { /* is only called when I intercept 2 Sessions */ } static switch_status_t channel_read_frame(switch_core_session_t *session, switch_frame_t *frame, switch_io_flag_t flags, int stream_id) { /* is only called when I intercept 2 Sessions */ } _________________________________________________________________ http://redirect.gimas.net/?n=M1003xHM5Adressen2 Ein Postfach für Alles – bei Hotmail 5 E-Mail-Adressen online verwalten!
