[App_rpt-users] Audio test server?

Is there a test server available on Asterisk, similar to EchoLink's Echotest or IRLP's Echo-Reflector? I wish to use something like this for test purposes, and to play back my audio. If this does not exist on Asterisk, perhaps it would be a good thing to add it to the wish list. Thanks... Best regards, Gary, K7EK
