Hello,
this should give you some ideas, e.g. just adding a sight delay to the Re-INVITE In Kamailio.

Hello, We encounter sometimes reinvite from some provider really quickly after 200 OK ACK so sometime there a race conditions where the re-invite exits Kamailio before the ACK leading to some Freeswitch “500 Overlapping Requests”.
[cid:image001.png@01D798FD.2A666360]
I tried to catch the 500 on failure-route unsuccessfully as transaction is already established.
Do you have any idea on how I could deal with this behavour ?
Running 5.3.6 with 8 childs modules used :(tm + dialog) No costly action performed on ack that can explain slowliness.
Regards, David
