Asterisk for making outgoing call to landline (USA)

I have worked on making an outgoing call to the extension configured in xlite softphone using SIP.conf and deliver the message. Now i need to call to landline numbers in USA and deliver the message to that called number. How to use Asterisk for making call to landline numbers. If i need to purchase something, do let me know what is the process.

How good is Skypho, can i use it for my development.

I can tell you Skypho is quite good, not without problems but getting better.

Bye.
