Hi all, We have identified an IMS related issue, when the “Content-Length” header is missing in REGISTER request. It’s a missing null pointer check in file modules/ims_auth/utils.c We are using Kamailio 4.4.5 for this purpose and we would need a fix in that release. *I’m not sure, how to proceed now?*Should I just *create an “Issue” at GitHub*, or is it possible for me to *create a “Pull Request” at GitHub* (would be less effort for you, I guess). Anyway, the change we did in our local GIT repository, is shown in following picture: Thanks, Christoph The information contained in this e-mail message is privileged and confidential and is for the exclusive use of the addressee.
