Asterisk conference bridge, call file syntax?

Question

Asterisk

Hello.
I'll get straight to the point.
There is a need to create a conference bridge using a call file, which will record a certain condition under which, by calling a certain number, there was a simultaneous call to the list of numbers specified in list.txt, which differ from each other not by one (like 101,102,103 ..), but scattered randomly (101,203,505..).

I don’t know about FreePBX, but on pure Asterisk, this can be done without a call file. Here is a dialplan that works for me, calls to the conference on the line **111*212*313*...*999

[Conference]
exten => _**XXX!,1,Set(Numbers=${EXTEN:1})
same => n(loop),GotoIf($["${Numbers:0:1}"!="*"]?end)
same => n(orig),Originate(SIP/${Numbers:1:3},exten,Conference,${CALLERID(num)},1,60)
same => n,Set(Numbers=${Numbers:4})
same => n,Goto(loop)
same => n(end),ConfBridge(${CALLERID(num)},bridge,simple)

exten => _XXX,1,Wait(1)
same => n,ConfBridge(${EXTEN},bridge,simple)
