Minimal Asterisk configuration with SIP

i have just installed ( for the first time) asterisknow.

As a first step i would want to make a simple configuration:

Server asterisknow with 2 SIP softphone client. my objective is to make that the two telephones are registered on the server and they can be called.

Is it enough the asterisknow server for this configuration or shud i have to install other services?

Thanks in advance

AsteriskNOW will be enough.
