thank you very much i will see kamailio 3.0 but is there any voip soft phone which support sctp, please?

Maybe pjsip? At least the type is defined (ask on pjsip list) http://www.pjsip.org/pjsip/docs/html/sip__types_8h.htm#281800a20f69fd1cfb7b5...

Otherwise you can test SCTP by using proxy-proxy communication with kamailio.
