   If UAS is getting the ACK with content-length more than the actual
   body length and all the headers are correct?

(I assume you mean "all the *other* headers are correct", as you're
assuming that Content-Length is incorrect.)

As others have noted, RFC 3261 demands that the ACK be discarded.  But
being an error situation, I suppose that your UA could process it as
if it is valid.  But the only valid body I know of for ACK is an SDP
answer.  If Content-Length does not agree with the length of the SDP
that is present, there is a good chance that the SDP has been damaged
and cannot be used to create a successful session.

Of course, what you really should do is yell at the other UA's
implementors and make them fix their ACK.
