Hi Joachim,
briefly, the flags are attached to the transaction - same flags are visible for request and its replies (and forks). Once the transaction is delete, the flags are also gone.

Hi,
Again a question regarding the OpenSER documentation, specifically the usage of flags: What is the context and visibility scope of flags in openser? What is their lifetime?
Maybe some piece of code to clarify things:
route { if (method=="REGISTER") { setflag(10); # do some processing }
if ((method=="INVITE")||(method=="BYE")) { setflag(11); }
# do some more processing t_relay(); }
onreply_route() { if (isflagset(10)) { # received a reply on register, process it } if (isflagset(11)) { # reply on invite or bye } }
a) Can we expect the flags 10/11 to be identical for route and onreply_route - i.e. in the example above, are the flags in status "set" when processing the onreply_route? I.e. isflagset(10) returns true if we process the 200 OK in reply to a REGISTER? b) Do we need to explicitely reset the flag or is it automatically cleared? Specifically: If an INVITE and the matching OK are processed, is it required to reset the flag afterwards in onreply_route? I.e., if after the 200OK to INVITE a 200 OK reply to a SUBSCRIBE is processed by onreply_route and we did _not_ reset the flag 11, does isflagset(11) return true or false on the 200 OK for SUBSCRIBE?
Finally another question: must onreply_route be explicitely triggered (like for onreply_route[1] using t_on_reply("1")) or is the default onreply_route anyhow executed automatically on any stateful reply?
Thanks in advance, --Joachim
