[asterisk-users] ConfBridge 1.6.20 user count

[asterisk users]

Hi all,

I'm using ConfBridge within Asterisk 1.6.20 and want to record the
conference, so I'd like to start the recording when the second user joins,
so in the example below, for example, how can I get the current user count
in ConfBridge 3000?

[conferences]
;authenticated conference (ext C-O-N-F = 2663)
exten => 2663,1,Answer
same => n,Wait(1)
same => n,Authenticate(143382)

;Record conference callscount: ${count} --)
same => n,Set(MONITOR_EXEC=/etc/asterisk/monitor_exec.sh)
same => n,Set(DATETIME=${STRFTIME(${EPOCH},,%C%y-%m%d-%H%M)})
same =>
n,ExecIf($[${count}=2]?Monitor(wav,conf-${CALLERID(num)}-${DATETIME},bm))
<-- count?

same => n(conf),ConfBridge(3000,Ms)
same => n,Playback(goodbye)
same => n,Hangup

Thanks for any ideas!
