Why don't you check yourself?
According to RFC 3261 SIP URI is not complete without hostport part:
SIP-URI          =  "sip:" [ userinfo ] hostport
                     uri-parameters [ headers ]

I think what you are getting is the effect of having the outbound proxy 
set without setting the SIP URL to call. You won't need to set outbound 
proxy after SIP URL to call is set correctly. Just in case manual of 
pjsua is located at http://www.pjsip.org/pjsua.htm
