I noticed this in t_newtrans() README:
Note that any flag operations (e.g. for accounting) after this function has been called will be ignored. You can use the the tmx module function t_flush_flags() to flush the altered flags to the already created transaction.
The text is wrong. I have for ages set bflags after calliing t_newtrans() and the sets are NOT ignored.
Here is an example:
In route blocks: Dec 12 08:41:53 /usr/bin/sip-proxy[231131]: INFO: ********* called t_newtrans() Dec 12 08:41:53 /usr/bin/sip-proxy[231131]: INFO: ************ set bflag 9
In failure route block: Dec 12 08:41:58 /usr/bin/sip-proxy[231195]: INFO: ************ bflag 9 is set
