[sr-dev] dlg_isflagset not working on CANCEL request

hello all Using kamailio 5.4 version, we have seen that dlg_isflagset is not detecting a dialog flag set in the request route for the initial INVITE, when a CANCEL request arrives. We have applied this change to set the dialog context unique ide for this request. Since it's done on dlg_onreply, dlg_onroute and dlg_ontimeout functions. This way, dlg_get_by_iuid(&dctx->iuid) in the function ki_dlg_isflagset is not NULL and dialog flags are detected. Is this change correct? Or can it generate any kind of issues? diff --git a/src/modules/dialog/dlg_handlers.c b/src/modules/dialog/dlg_handlers.c index 3f8adefb79..f1df4a76c5 100644 --- a/src/modules/dialog/dlg_handlers.c +++ b/src/modules/dialog/dlg_handlers.c @@ -1255,6 +1255,9 @@ dlg_cell_t *dlg_lookup_msg_dialog(sip_msg_t *msg, unsigned int *dir) msg->callid->body.len, msg->callid->body.s); return NULL; } + if(msg->first_line.u.request.method_value == METHOD_CANCEL) { + dlg_set_ctx_iuid(dlg); + } if(dir) *dir = vdir; return dlg; } thanks a lot and regards David -- <http://www.sonoc.io/> David Escartín NOC engineer *www.sonoc.io* <http://www.sonoc.io/> [image: LinkedIn] <https://www.linkedin.com/company/sonoc> [image: Twitter] <https://twitter.com/sonoc_> [image: Facebook] <https://www.facebook.com/SONOCio/> This e-mail is for the exclusive use of its recipients and may contain business secrets or other confidential or privileged information.
