The pjsip_find_msg() is used when in TCP to find the message boundaries in the stream. For that, it uses the Content-Length field, which is only mandatory in SIP TCP according to spec. Since this function is used only in TCP transport, that's totally fine. However, a SIP test written in TTCN-3 was recently sending a message without Content-Length field (because there was no body at all in the message). That made Asterisk discard the message without any kind of feedback, as if it was a black hole. Write down some log line explaining the user that a Content-Length value is expected.

Right, incoming message without |

@trengginas what you suggest is done in my other PR (#3961). I still think it's fine to merge this PR as it is now, so that logging provides the exact reason of the failure. |

* Add missing openssl SECLEVEL=0 support (pjsip#3890) Previous SECLEVEL support allowed for levels 1-5. However, openssl defines levels 0-5. [1] Recent openssl versions (3.0+) have moved previous popular ciphers/key lengths (i.e. RSA1024withSHA1) into level 0, so it is now a reasonable choice to use. Add support for level 0.
