[Asterisk-Users] trying to set an internal ivr

[PAZ]

Hello:
	I'm trying to implement an IVR for internal use for the 
enterprise I work for, but the goal I'm trying to reach is that the 
main menu of this IVR present itself to the user after 5 seconds he picks 
up his extension (and only if the user doesn't press any key, off course). 
I imagine the solution (if exists) maybe relies in timeout properties,
but I can't see it. Any suggestions for my extension.conf file ?.
