Just to clarify, a bit, I earlier said:

All statistics reported by CU-SeeMe refer to the UDP payload. I.e., they
do not include IP headers (20 bytes/packet), UDP headers (8 bytes/packet)
or any lower level framing. For 50 ms audio, at 20 packets/second, IP+UDP
headers would add an additional 4.4 Kbps. Note, however, that most SLIP
software has facilities for header compression, so it's hard to gauge the
real impact.
