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
