[Kamailio-Devel] 200 ok to pua does not work

[Juha Heinanen]

i have noticed that there has been some messages about not matching 200
ok (or something like that).  perhaps what i'm seeing is related:

- i send PUBLISH to kamailio via pua_mi interface

- kamailio pua module sends PUBLISH back to kamailio

- kamailio replies with 200 ok to itself

- this 200 ok is either never passed to pua or pua does not match it,
  because pua keeps on re-sending PUBLISH

i don't see the problem every time, but quite often.

does this look like what other people have reported?
