Hi Michael,
that is correct. just note you may encounter some races between INVITEs
and CANCELs in the case of a fast CANCEL (CANCEL follows the INVITE
almost instantly) - when one process is still handling the INVITE (the
transaction may not be build yet), another process receives the CANCEL
and it will not be able to match it to a transaction in this case, the
CANCEL will be forward based on its RURI without any info from INVITE.....

Hello,
I have a question about CANCEL processing.
I read on the mailing list that CANCEL will be automatically matched by t_relay
to transaction it's cancelling, if needed transformation to RURI will be automatically
applied and then it will be automatically send to correct destination.
I'm experimenting with openser 0.10.x and it seems to be true, but I'd like to
confirm
that the following is OK:
if (loose_route()) {
do something
t_relay();
break;
}
if (is_method("CANCEL")) {
t_relay();
break;
}
if (uri==myself) {
do lookups that rewrite RURI
t_relay();
}
Thank you,
