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.

Yes this fixes my issue.
