I just opened ASTERISK-23746 which would have been "helped" by a Timer C. We ran the same test through OpenSIPS and things tore down correctly because of the availability of Timer C there. Not sure if this particular review would have helped, but at least it provides an example of a situation where Timer C could have helped with port exhaustion.

Of course the issue also identifies a problem with what Asterisk is doing as well, so this would not be the solution, but would certainly have helped.
