A clarification here on an old thread.
A UAS should still be prepared to receive a UDP request without
content-length. If none is present, the body encompasses the rest of the UDP
packet. That has nothing to do with multiple SIP messages per UDP datagram.
The "Content Length Required" error message has been removed from bis, since
you need to be prepared to get the body from the remainder of the UDP
datagram.
