[App_rpt-users] My new challenge

Ok, this can't be as hard as it appears. How on earth can you pass dtmf through once you are linked to a node? Scenario User connects to node A, node A is connected to a box that wants DTMF to control it. User A wants to go into some form of *mode*, where they can enter DTMF from a mic keypad and have it sent (not mutted) to the box connected on node A. I at first thought it was command mode, but no, that just sends the command sequences (not dtmf) in the software to deal with remote commanding. I want to send live DTMF. Another option, is perhaps there is a way to not mute DTMF on a node stanza basis? Thanks, Alan
