asterisk users - May 2004 - Syntax (2)

Hi 

I start my asterisk and i can register my two sip phones .. but when i try
to make a call ( in the form : user@server) from the Kphone they returns
: "Call Failed: Not Found"

The extensions.conf is the default, only in sip.conf i add the peers ..


what's wrong ?


Regards, 


Ivan
