I try to write an application based on JAIN SIP (It's call 2 voipbuster account). But it's too complicated, anybody know a top level API based on JAIN SIP? I want only set the server host and port, the caller user name and password and the called user data (and maybe the Session Descriptor). After the call successfuly I want to connect the two account RTP communication, and if somebody disconnect send a Bye to the another user.
With JAIN SIP I can call authenticated but after one min VOIPBUSTER drop the connection (nothing happened, the remote side sent 3 "Transaction terminated event" and after than a bye...).
I think jain sip is very good but a little bit too low level.
