[App_rpt-users] change function stanza

is there a way to switch the function stanza with a dtmf command? Here's my issue. I have some prerecorded audio clips that can be called via dtmf commands. They're goofy things like canned laughs and applause clips. I use the "playback" versus the "localplay" so the files will play on my 4 nodes that are permanently connected. The issue is that we link the system to a state wide ARES net on Sundays, i obviously don't want those going out over the net. Is there a way that I can call a different function stanza before the net which doesn't contain the commands to call those audio clips? thanks and 73 de K0JSC
