Hi Ovidiu,
So you are saying that despite ngrep does not show it, the whole packet is correctly sent?
thank you
George

Hi Georgios,
It seems that your packet is to big and it was fragmented (udp fragmentation). OpenSER is able to deal with fragmented packets (both sending and receiving).

Hello all,
I am noticing that OpenSER relays an INVITE and the packet that is sent out is clipped. You can see in the following packets that the forwarded packet is missing a few bytes from the SDP part. Counting the bytes shows that the outgoing packet is always 1512
bytes. Is this
something that has do with OpenSER (module parameter,
compile options) or is it OS related?
thank you for any help
George
