[Freeswitch-users] Question on switch_core_media_bug_add

The channel is an outgoing channel created with originate in a C module
(inside a thread that read db and make the originate) with:

status  = switch_ivr_originate(NULL, &session, &cause, dialstring, 60,
NULL, NULL, NULL, NULL, NULL, SOF_NO_LIMITS, NULL);

where dialstring like "sofia/external/xxx at yyy"

and when:

channel = switch_core_session_get_channel(session);
switch_channel_test_flag(channel, CF_EARLY_MEDIA)

I do:

media = switch_core_media_bug_add(session, "myfunc", NULL, mycallback, sth,
0, SMBF_READ_REPLACE, &bug);

but 'mycallback' is called with type=SWITCH_ABC_TYPE_READ_REPLACE only when
the channel is answered and not during early media.
