I am looking for comments and opinions on the current state of Call Progress Analysis (CPA) with FreeSwitch.  I believe Sangoma has a solution with their Lyra product but that a current module for that product is still in development.  At one time, work was being done with LumenVox, but that has stopped.  There was a module (mod_woomera), part of Dialogic, but it is over two years old.  And there is the VMD and AVMD modules that indicate a high processing load to run effectively.  Mostly, it seems that any CPA used needs to run separate from FreeSwitch in a proxy or re-directed mode to be effective under any kind of heavy load.

A few years ago, this topic was popular, but lately it has either been regulated out of existence or found to be in-effective.  Is there anyone with experience using call progress analysis or opinions on the topic?

Thanks,
