Interesting, sure enough it's set to this:
exten => 103,1,Set(__RINGTIMER=${IF($["${DB(AMPUSER/103/ringtimer)}" > "0"]?${DB(AMPUSER/103/ringtimer)}:${RINGTIMER_DEFAULT})})
exten => 103,n,Macro(exten-vm,novm,103,0,0,0)I'm assuming I don't want to be modifying these files by hand as they'll get stomped out by FreePBX when it rebuilds configs?
