Hi, Kamailio 1.5.4, let's suppose this case:
1) A dialog in eary state (state 2):
~# kamctl fifo profile_list_dlgs out
dialog:: hash=1055:330534072
state:: 2
2) Now try to terminate it:
~# kamctl fifo dlg_end_dlg 1055 330534072
3) It produces an error because in the early dialog there is no
Contact for the called:
ERROR:dialog:build_dlg_t: no contact available
ERROR:dialog:send_bye: failed to create dlg_t
CRITICAL:dialog:log_next_state_dlg: bogus event 7 in state 2 for dlg
0x7f25f0cde718 [3168:435552476] with clid 'hqpprxbyruti...@ibc-torre'
and tags 'ysldc' ''
4) The dialog remains in state 2 (as the MI command shows), and later
it's cancelled by the UAC.
5) MI profile_list_dlgs out will show the dialog in state 5 *forever*,
it's never deleted from memory! (perhaps it's after expiration time,
haven't checked it).
NOTE: I do know that dlg_end_dlg is not ready for early dialogs, as it
should trigger a transaction cancel (CANCEL to all the branches and
408 to the UAC) rather than sending a BYE, but this feature is not
implemented.
However the current code could leak.
