We are running UDP traffic. During heavy load FS receives sometimes receives 180 response after 200 OK already received on the same call-id (dialog). However FS does not discard the same and starts processing 180 even though it has already received 200 OK on the same call-id (dialog).

Freeswitch should be discarding the 180 response after it gets 200 OK response from far-end.

In our case the FS core state machine even though it gets 200 OK waits for 200 Ok again.

Thanks
