Packet-size in Bytes for a number of trunked-channels, for different codecs and protocols.


N.B. TCP-packets are often about 1500 bytes each. We assume these numbers are calculated and not measured, since the packet-size seems to double, each time the number of channels doubles.

N.B.2 For a two-way conversation, 2 channels are needed.
