Hi, $dlg_var is not available at this stage of the dialog: http://www.kamailio.org/docs/modules/devel/modules/dialog.html#idp19330392 To achieve your goal you can use there an avp or a flag, which are bound to transactions. Something like: #define INIT_FLAG if (is_method("INVITE") && !has_totag()) { $avp(is_init_invite) = 1; # or # setflag(INIT_FLAG); } onreply_route { if (is_method("INVITE") && t_check_status("200") && $avp(is_init_invite) == "1") { # or # if (is_method("INVITE") && t_check_status("200") && isflagset(INIT_FLAG)) # # do somting } } Regards, Federico On Thu, Mar 3, 2016 at 4:55 AM, 张顺通 <shuntongzhang(a)gmail.com> wrote:

I want to distingguish 200 OK is for INVITE or reINVITE。 so I do this: request_route { if (is_method("INVITE") && !has_totag()) { $dlg_var(is_init_invite) = "1"; } } onreply_route { xlog("L_INFO","[$rs-$rr][is_init_invite:$dlg_var(is_init_invite)]"); if (is_method("INVITE") && t_check_status("200") && $dlg_var(is_init_invite) == "1") { # do somting $dlg_var(is_init_invite) = "0"; } xlog("L_INFO","[$rs-$rr][is_init_invite:$dlg_var(is_init_invite)]"); } What I confuse is： When I recive 100 Trying LOG is [100 - Trying][is_init_invite:0] [100 - Trying][is_init_invite:1] why is_init_invite is 0? _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users

Hi, If I understood correctly the original question was to identify, in a reply route, a 200 OK coming for an initial INVITE. In the reply route the 200 OK will always have a to tag (unless the UAS is broken), so you cannot this condition. Regards, Federico On Thu, Mar 3, 2016 at 9:05 AM, Serge S.

Hi, Sorry, but why not to check has_totag again?

Hello, I am using two different on_reply routes: if (is_method("INVITE") && !has_totag()) { ....... t_on_reply(REPLY_TO_SOURCE); } route[WITHINDLG] { if(has_to_tag()) { ........ t_on_reply(REPLY_IN_DIALOG); } May be it will help. Best regards, Julia. On Thu, Mar 3, 2016 at 10:57 AM, Federico Cabiddu < federico.cabiddu(a)gmail.com> wrote:
