Al,

 

Are you doing voice broadcasting – that is, delivering a pre-recorded message, possibly giving a live caller other options?  Just curious.  I’ve been working on a voice-broadcasting application myself and I’ve had mixed success with app_amd.c.  It does work very well in some cases, but not so well in others.

 

I’m currently experimenting with the dialplan app BackgroundDetect.  For voice broadcasting apps, BackgroundDetect has the advantage of playing the message to the caller while simultaneously listening for a live caller or an answering machine.  This gets rid of the annoying pause that the caller hears after saying, “Hello.”  

 

Here’s where I got the idea:

See the section “Basic Answering Machine Detection.”

MC

Hi -

 

I have been developing an auto-dialling application similar to Voiceshot, Call-em-all etc. The one thing I am now struggling to get working is the ability to leave a message on an answering machine or cell phone voicemail. I am using app_amd.c and while it works well for some phones it is proving to be very difficult tweaking the settings to get it to work reliable enough to go to production. If anyone is using this successfully in a production environment I would really appreciate any posts of settings you are using. My settings are as follows:

 

AMD(3500|1500|300|5000|120|50|5|256)

 

Thank you.

Alan.
