Agreed suggesting UDP port 0 is reserved in SIP to decline the RTP
stream without ignoring it. The better question is WHY does linphone,
when configured to use H264 then decline it. Was a linphone binary
released with missing libraries or un(der)declared/documented (as in "I
could not find reference to it") dependencies?

Hi Robin,
There's nothing wrong with that. This is the standard way to remove a
stream. Look at the section 8.2 "Removing a Media Stream" of the SDP RFC
(3264) <https://www.ietf.org/rfc/rfc3264.txt>.
In your case, you performing a call proposing the use of H.264 for video
to a client that does not support H.264. Therefore this client answers
the call removing the video stream that it just cannot support.
Cheers,
Ghislain
