[SR-Users] Using flags in t_branch_timeout() section of failure_route{}

Hi all, I'm having issues using flags in a t_branch_timeout() of failure_route{} A brief summary of the code - onreply_route{ setflag(14); } failure_route { if (t_branch_timeout()) { xlog("L_ALERT","t_branch_timeout()\n$mb"); if (isflagset(14)) { xlog("L_ALERT","isflagset(14) - YES\n$mb"); } } } The call flow is below, t_branch_timeout() is being triggered when the 200 OK is not ACK'd -- INVITE -> <- 100 Trying -- <- 180 Ringing -- <- 200 OK -- <- 200 OK -- <- 200 OK -- <- 200 OK -- I can attempt to create a minimal .cfg if anyone wishes to replicate it, assuming I'm not missing something stupid. Thanks, Matthew
