Hi all, I'm wondering what the syntax is to call a shell script from a DTMF command in app_rpt - or even if this is possible? What I'm trying to do is a variation on the method described by Steve earlier to inhibit incoming calls. What I intend to to is this: When the user keys a specific DTMF code, have a script run which renames IRLP.conf as somethingelse.conf ad then restart asterisk, so effectively disabling IRLP part of the node. I will do the same with Echolink but with a different code..... I've tried using the dialplan to call some announcements just to see if it worked - it didnt! Here is what I put in my dialplan ( I tried under Default and also Radio-secure stanzas ) exten => *990,1,Answer exten => *990,n,Wait 1 exten => *990,n,Playback,rpt/connected exten => *990,n,Playback,rpt/functioncomplete exten => *990,n,Hangup So, I wonder what I'm doing wrong here - I thought I'd try and get this working before going on to use the *990,n,system(script_directory/script) method. Is it possible to call a system command from rpt.conf instead? Thanks for all your patience! Matt G4RKY
