I need to make a call through sip server . i have very little knowladge abt sip. I have found some link in the wiki
link 1 describes how to send a message to the sip server . I think i can send a invite request to sip server in the same manner.
link2 describes abt how to listen to incoming voip calls but how to make a new voip call.
Atlast i have seen an aplication which make such calls here below
Any help solving these queries will be highly apreciated..
