I followed these instructions for Mod_vmd except for a Windows box:

http://wiki.freeswitch.org/wiki/Mod_vmd

I tried testing to see if it's working by dialing the following extension:

<!-- mod_vmd test extension (new mod)-->
<extension name="vmdtest">
<condition field="destination_number" expression="^5555$">
<action application="answer"/>
<action application="info"/>
<action application="vmd"/>
<action application="sleep" data="25000"/>
<action application="info"/> <!-- Look for chan var "vmd_detect" here -->
<action application="hangup"/>
</condition>
</extension>

However, I didn't see channel variable "vmd_detect" in the FreeSwitch console.

Mark,

It does work ... but I can't really attest to how well ... especially compared to other things out there.  I started capturing this in CDR's to see and it didn't seem like it worked very well.

If this is really critical to you, you might want to ping Ken Rice.  I know he might have a better option.

I'm wondering why there was nothing in the console showing the channel variable ${vmd_detect} as the wiki says there should be:

[sicfslist at gmail.com]

Mark,

Because it didn't detect a "beep".  It will be be there as vmd_detect=true if it does.  I'm not sure exactly how reliable it's "beep" detection is.

Another issue with this module is the resources it consumes. We had it running on 50 calls yesterday and the cpu’s all went to 90+%

I added a voicemail tag in 5555 to a default extension 1001, I hear the voicemail beep but still don't see vmd_detect.

Hi MC,

With trunk 12638M, I tried checking vmd internally and externally to my cell.
No luck at all in detecting a voicemail (beep).
I used the following extensions to test this, maybe they are in error.

If not then how else can I detect from FS that I got voicemail in a phone agnostic way (i.e, pots & sip).

<extension name="110">
<condition field="destination_number" expression="^110$">
<action application="answer"/>
<action application="vmd"/>
<!--<action application="voicemail" data="default 10.0.0.3 1000"/>-->
<action application="bridge" data="sofia/gateway/spa3102PSTN/12223334444@10.0.0.5:5061"/>
<action application="transfer" data="111 XML default"/>
</condition>
</extension>

<extension name="111">
<condition field="destination_number" expression="^111$"/>
<condition field="${vmd_detect}" expression="^TRUE">
<action application="answer"/>
<action application="speak" data="flite|kal|voicemail detected"/>
<action application="hangup"/>

<anti-action application="answer"/>
<anti-action application="speak" data="flite|kal|no voicemail detected"/>
<anti-action application="hangup"/>
</condition>
</extension>

Mark.

Hmm,

Well We're connected direct to E1's and it doesn't work reliably here.
That said, DTMF detect does recognise the beeps most of the time.
Perhaps there's a regional variation. I wonder if it's country
specific. The code looks logical. When I get some time I'll have a
look at it and see how it can be improved.

The concept is great and is much better that sniffing out human voice as
that's prone to false positives. Much better to assume human and
machine. Nothing worse than a silent call.

Regards,

Ironically, I've used tone_detect to try and trap SIT tones and I
found that answering machines in the USA seem to all send a beep in
the same freq range as American SIT tones...

tone_detect! sounds good.

BTW, was there any errors in those extensions I posted. I modified something you posted MC.

I put this after the "vmd" tag

<action application="playback" data="SIT/IO_SIT.wav"/>

to check vmd with tones found on this page

http://en.wikipedia.org/wiki/Special_information_tone

I converted them over with Audacity to wav files and "vmd" worked in finding a "beep" but the format was wrong for FS.
However, after I switch the format of the audio files to something FS likes then vmd would not detect the tones.

Is there some good test tones for the U.S phone system I could use to check both mod_vmd and tone_detect?

Thanks. Mark.
