The meaning of "debug vpm" 's output.

I am looking for where can I get the meaning of debug vpm's output, specially the lines below:

May 5 06:57:56: [2/0/0, EM_WAIT_FOR_ANSWER, E_HTSP_VOICE_CUT_THROUGH]

May 5 06:57:59: htsp_dsp_message: SEND/RESP_SIG_STATUS: state=0xC timestamp=649

24 systime=259680172

May 5 06:57:59: [2/0/0, EM_WAIT_FOR_ANSWER, E_DSP_SIG_1100] em_wait_answer_offh

ook

May 5 06:57:59: em_stop_timers

May 5 06:57:59: htsp_timer_stop

May 5 06:57:59: htsp_timer_stop2 htsp_release_req: cause 16, no_onhook 0

Why did it get released ?

Re: The meaning of "debug vpm" 's output.

This is obviosly an e&m debug output. The

e&M interface must first wait on answer which is a wink from the remote end

signifying off-hook before the voice path is cut through for audio.

The debug show we waited till the till the timer expire for a wink

May 5 06:57:59: em_stop_timers

After which that causes the calls to be droped May 5 06:57:59: htsp_timer_stop2 htsp_release_req: cause 16,no_onhook 0

The cause code 16 hear means cause-code 10 normal call clearing. But the fact is we did not get an answer from the remote end so we droped the call

Check you e&m configs for more troubleshooting
