Unless I'm complicating things, it seems like a drop to write outbound event sockets apps versus writing embedded language apps. However, I'm interested in writing event sockets apps because I can see an advantage in being able to load balance the app by running you app behind a load balancer. One simple thing that I am trying to accomplish is collecting digits and doing something useful with string of digits that have been collected. My first attempt at this is to use the play_and_get_digits dptool, but I don't now how to pull data from stored variable so that I can use in the script. I slightly modified the freeswitch.git/libs/esl/perl/server2.plscript by adding this line: $con->execute('play_and_get_digits', '2 5 3 7000 # ${base_dir}/sounds/en/us/callie/conference/8000/conf-pin.wav /invalid.wav foobar \d+' ); The next thing that I'd like to do is grab the value in foobar is use it in the perl logic. Can someone lead me to the next step? Does anyone with experience with event socket apps and embedded language apps have some useful information about their preferred path? Thanks, Herman
