Is this possible with ASTERISK?

Hey,

Can PJSUA and asterisk work together like the below to call any phone( PC-PHONE) ?

pjsua.exe --id= sip:brat@brat.asteriskserver.com --registrar= sip:sip.asterisk.com --realm=* --username= brat --password= mypassword.

press 9 or m ( to make call ) on pjsua command-line, then enter the below command:

sip:423-222-3333@user.asteriskserver.com

The above will make a call to 423-222-3333, using asterisk provided they have proper dialplan and SIP proxy to handle the call from PC-PHONE.
