Hi,
Using kamailio 1.4.2, I experienced this :
A INVITE -> kamailio
kamailio INVITE -> B
B does not send any provisional, my config enables fail over (serial
forking) when B does not answer so :
kamailio retransmit INVITE to B.
then kamailio fails over to C
kamailio INVITE -> C
C 180 -> kamailio
kamailio 180 -> A
Then B answers 200 OK. (It's alive !)
B 200 -> kamailio
tm does not relay.
Retransmission :
B 200 -> kamailio
tm does not relay.
Then C :
C 200 -> kamailio
kamailio 200 -> A
Dialog is established between A and C
B goes on retransmitting 200 Ok, kamailio TM drops it.
Then A/C dialogs ends with BYE
C BYE -> kamailio
kamailio BYE -> A
A 200 -> kamailio
kamailio 200 -> C
B goes on retransmitting 200 Ok
B 200 -> kamailio
*and kamailio relays the answer*
kamailio 200 -> A
NOTE that dialog module complains :
