Sorry, I'll rephrase what I meant.
The general case is given: c= lines are mandatory in m= lines.
The sub-case of rejected m= line is not mentioned, therefore the general
case applies, and therefore the c= line is mandatory.
It is not left for the implementor to decide.

Hi,
RFC 4566, just where c= lines are defined:
5.7. Connection Data ("c=")
c=<nettype> <addrtype> <connection-address>
The "c=" field contains connection data.
A session description MUST contain either at least one "c="
field in
each media description or a single "c=" field at the session level.
It MAY contain a single session-level "c=" field and additional
"c="
field(s) per media description, in which case the per-media values
override the session-level settings for the respective media.
No mention of rejected media descriptions, so it applies to all!

Hi all,
I recently ran into an intro issue with some unknown SIP
device. My client uses a per-stream SDP connection line, but
when a stream is disabled (port set to 0) the stream is just
reduced to the m= line.
Technically I could put the connection line at the session
level in some cases, but it could be that I need to have it at
the stream level. Should I also add it for disabled streams?
FWIW, doing so made the aforementioned SIP device happy, but I
couldn’t find any RFC reference which stated it’s always required.
Any clarification (or recommendation) would be appreciated,
thanks!
