RE: [Sip] Open Issue #150: too many ways of saying "don't send me media"

["Eric Burger" <eburger@snowshore.com>]

Does it really matter?  Unless the semantics are unclear or you want to use
it for something else, why impose limits on SDP?  People can do whatever
works; we should document the preferred way of doing things and explain why
you shouldn't do others, like the problems with 0.0.0.0.

Subject: [Sip] Open Issue #150: too many ways of saying "don't send me
media"


Issue:

There are a bunch of ways to say "don't send me media":

c=0.0.0.0
a=inactive,sendonly
zero port
bw=0

What do these all mean, and do we need them all?

Discussion: We've agreed on most of this already. The only real issue is to
say that bw=0 is never used. So, the proposal is:

c=0.0.0.0          DEPRECATED
a=inactive,sendly  PREFERRED
zero port:         disables media stream
bw=0               DONT USE
