Hello, I am able to receive INVITE from X-LITE with TCP but my server does not accept INVITE that my client sends. My dest uri is built like that: pj_str_t dst = pj_str("sip:" "8000@" SIP_DOMAIN ";transport=tcp;hide"); And the INVITE looks like that: INVITE sip:8000@my_sip_server.com;transport=tcp;hide SIP/2.0 Please save me! Thanks and regards, Dan
