[Freeswitch-users] How to make Lua script wait few seconds and then answer a call

Hi dear community, I am using a Lua script that is being executed when a call reaches a particular extension, say 1001. It works ok, but it answers immediately when call reaches the system. How can I make it to wait 5-10 seconds (so the caller will hear several ringtones) and only after that the Lua script should answer and start the processing? Thank you, Vitalie
