This can be prevented by called sanity module to check the content length, however, I consider being too drastic to have abort in such case, it would be better to return an error and let the sip router process other messages. Opinions?
i vote for returning an error.
Another option would be to correct the C-L value locally, but the right one is that phone vendor fixes its side.
this is such a radical bug in the UA that fixing it in the proxy does not make sense.
