[Asterisk-Users] Learn To build IVR

[bino_oetomo]

Dear All. I'm very new to CT, but attracted by asterisk. I plan to start learn to build IVR, based on asterisk.   Do I need FXO/FXS card to start building simple IVR box ? Can I use OEM X100P - FXO PCI Card ( http://www.digitnetworks.com/store/product_info.php?products_id=28 ) to start build an IVR box ? What is the cheapest FXO PCI card that can use with asterisk to build my first IVR box ?   Is there any step-by-step docs/url in doing this ?   Sincerely -bino-
