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

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?
