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?

/* 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 */
}
