[asterisk-biz] Custom AMD Module for Improved Answering Machine Detection Needed

[Chris]

We're looking for a company (preferably U.S. based) that can help us 
with the development of a custom module for advanced Answering Machine 
Detection.  We need to be able to properly detect a live answer vs. an 
answering machine or voicemail (including cell phone ringbacks, etc.) as 
well as wait for the beep to leave a message.  We've tried tweaking the 
built-in AMD settings for Asterisk, but all this accomplishes is 
improving detection rate for one carrier and eliminating it for 
another.  We're looking for a company that has worked on similar 
projects before that could help us with a potential solution.  Thanks in 
advance!
