There are many
other cases when a single dialog approach is breaking
other things. For instance, the qos module is keeping track of the
media connections between the two endpoints. In a single dialog
approach, this will not work.
Could you elaborate on this please? I'm wondering because the number of
media connections should not change no matter how many spirals there
are, no matter whether there is just one or multiple dialogs used to
track the spiraled call flow. It will still be just one end-to-end SIP
connection with a single media connection.
Just assume that P2 is proxying media using the nathelper module. In
this case, the media endpoint are different for the first and the
second dialog on P1.
