Sure, but a media channel(d) is NOT ALWAYS created after a signaling
channel(s). A signaling channel can also be created and followed by e.g. 2
streams - the 2nd stream channel(d) will be detected as a signaling channel.
Also, in case of recovery and reporting services additional channels may be
created, so simply counting the channels will only work in the most simple
cases.

In the capture file, a signaling channel is established(#1) and before a stream
is created the channel is closed again. Then a new signaling channel is
established(#2) followed by a stream/media channel (#3).
