Re: [OpenSIPS-Users] incorrect content length in body part

Tue, 03 Mar 2020 01:13:53 -0800 

Hi, Kamlesh!

Try to remove the Content-Length too, using remove_hf("Content-Length").
If this still does not work, please open a bug report[1].

We want to remove the body part in this packet so that we used remove_body_part("application/vnd.etsi.pstn+xml") exported functions. It was removed successfully but the Content-Length was added. You can check we have two Content-Length headers in the packet.
