WebConf : ConfBridge

This is a simple example of confbridge with admin/guest mode.

call 8001 to enter call conference room N° 1 as guest or admin depending on PIN code used.
Guest cannot speak before admin is connected.
Guest is unconnected when all admin leave.

You must setup PIN codes for guest and admin via phone :

8101 : setup guest PIN code for conf room N° 1
8201 : setup admin PIN code for conf room N° 1

or create config files like :

echo "123" > /var/spool/asterisk/confbridge/confbridge-name-1-user.txt
echo "456" > /var/spool/asterisk/confbridge/confbridge-name-1-user.txt
