mediaproxy module and ACK with SDP
by Jasmin Schnatterbeck 19 Dec '11

19 Dec '11

Hello, I've just recognized, that the mediaproxy module does not adjust the SDP connection info of dialog-confirming ACKs (kamailio 3.2.1). mediaproxy.c registers for the following dialog req callbacks: mediaproxy.c:1955 if (dlg_api.register_dlgcb(dlg, DLGCB_REQ_WITHIN, __dialog_requests, (void*)ice_data, __free_dialog_data) != 0) But in dlg_handlers.c 1194 if (old_state==DLG_STATE_CONFIRMED_NA) { 1195 LM_DBG("confirming ACK successfully processed\n"); 1196 1197 /* confirming ACK request */ 1198 run_dlg_callbacks( DLGCB_CONFIRMED, dlg, req, NULL, dir, 0); 1199 } else { 1200 LM_DBG("sequential request successfully processed\n"); 1201 1202 /* within dialog request */ 1203 run_dlg_callbacks( DLGCB_REQ_WITHIN, dlg, req, NULL, dir, 0); So DLGCB_REQ_WITHIN does not seem to be called for the dialog-confirming ACK (because it's no request WITHIN the dlg). If UA sends such an ACK request with SDP, mediaproxy does not correct the connection info. I suggest to change mediaproxy.c:1955 to: if (dlg_api.register_dlgcb(dlg, DLGCB_REQ_WITHIN | DLGCB_CONFIRMED, __dialog_requests, (void*)ice_data, __free_dialog_data) != 0) Regards Jasmin
