Hi again,
- OpenSER in addition continues to forward the already rejected INVITE
transaction with "100 Giving a try"(packet 19) and forwards the INVITE to the UAS (packet 20).
The next issue I discovered is with the UAC (Xlite): The repeated INVITE (caused by the 422 Response) does not increment the CSeq header field so that it is regarded as same request leading to a "482 Merged request" rejection at the UAS (Eyebeam).
I have another trace-file attached without above mentioned Xlite-problem. Eybeam correctly increases CSeq header field and so two "different" INVITE requests (packet 14 and 16) arrive at the peer client.
Best regards and a peaceful and happy new year to everyone. Franz
