At some moment in past, the text above the arrows became truncated not to exceed the length of the arrow itself. So in the current implementation, an interesting part of the information (codec list in SIP messages, DTMF symbols in RTP flows, ...?) is not shown if the arrow runs between directly adjacent vertical lines representing communication endpoints. As the position of the dashed lines is fixed, and also no "help bubble" appears when keeping the mouse cursor above the arrow or text for a while, the only way to read the information is to click the arrow and change focus to the main window and read the information from packet list or packet dissection pane.
My enhancement suggestion is to return to the previous method, which I assume was truncation of the text to the full width of the pane rather than to the length of the arrow. There should be no risk of conflict with other text as (intrinsically) no arrow ever shares its vertical position with any other one. The positioning of the text should be as close to "symmetric over the arrow's center" as possible so that the text would never be completely detached from the arrow, and truncated from the right if necessary to fit to the pane width.
I don't think that moving the SDP contents to the "comment" pane and keeping only the message name over the arrow would be a good idea, first because the comment pane would become too crowded and second because everybody has been already used to see the SDP etc. over the arrow together with the message name and the application level address information (From:, To: contents) in the Comment pane.

As the position of the dashed lines is fixed
This was #10693 (closed), which was fixed six years ago (after this bug was filed.) My thought is that the ability to zoom in and out to change the width solves the problem and the bug is a duplicate.
