[at first,I'm sorry for my poor chinese english.]queue keypress events don't work, asterisk seems not to receive DTMF keys when waiting in a queue, when i enter any digit key, expect to exit the queue and go to a voice menu context corresponding to "context" config item in queues.conf, but i always failed. i debug this by GDB, i know asterisk call wait_a_bit in queue_exec() function at app_queue.c to receive a single digit DTMF key to exit, and i go deep into call stack of wait_a_bit, the program return "ast_null_frame" at "case AST_TIMING_EVENT_EXPIRED" after calling ast_timer_get_event in __ast_read.
