Traversal media port range For traversal calls (i.e. where the VCS is taking
the media as well as the signaling), the range
of ports to be used for the media. Ports are
allocated from this range in pairs, the first of
each being even. Therefore the range must
start with an even number. See
Configuring the
Traversal Subzone ports
for more information.
