Hello All, I am using siphone with tcp. It is registered properly. But when i make a call via tcp this function is not called in sip_inv.c: pj_status_t <http://www.pjsip.org/pjlib/docs/html/group__PJ__BASIC.htm#gab43ba3167bd2a2ab4580509dbf79200e> pjsip_inv_uac_restart ( pjsip_inv_session <http://www.pjsip.org/pjsip/docs/html/structpjsip__inv__session.htm> * *inv*, pj_bool_t <http://www.pjsip.org/pjlib/docs/html/group__PJ__BASIC.htm#ga1dc7a356fb36bd2dee2bc7d6c7e817e4> *new_offer* ) So with tcp call is disconnected because this function is not called.But with udp call is connected. i think it is needed when 407 registation time out comes in sending INVITE. but with UDP its getting called but not with TCP. So please suggest me some solutions thus i can resolve this issue. Thanks and Regards Ashish Gour -------------- next part -------------- An HTML attachment was scrubbed...
