[Freeswitch-users] bgapi uuid_kill question

Hi, Trying to kill a channel (hangup) when it's in CHANNEL_EXECUTE state as per mod_socket_event event information I use bgapi uuid_kill <core_uuid> - but get response "ERR no such channel!". Same happens if I use unique_id or channel_name as an argument to uuid_kill. What I am doing wrong? Help would much appreciated. Thx.
