[Asterisk-Users] Newbie question about pressing a key to be connected to the caller

[Jason]

I have a newbie question about the dialplan. I have a main menu that 
picks up on a certain DID number, and gives a list of options. When an 
option is selected, for instance 1 for sales, it rings a number of users 
in succession until one picks up and is connected to the caller, 
otherwise it goes to voicemail. This is all working well. However, I 
would like to have the system play a message to the user when they pick 
up, saying "There is a call for sales, press 1 to accept the call or 2 
to ignore". If the user pressed 1 they would then be connected to the 
person calling in, if 2 it would just go to the next person in the 
group. Any help would be appreciated, my current context is below for 
reference:

[ext-sales]
