Summary:                    Image media line with port set to 0 is considered
active
Description: 
When parsing SDP containing an image media line with a port set to 0 (to
specify it as inactive), T.38 is considered enable but should not.

ex: m=image 0 udptl t38

This block scenarios where an initial INVITE contains both audio an image
and image is disabled afterward for an audio only call using a Re-INVITE.
