Hello,
can you try with latest git branch 5.4? I just pushed a commit to handle
this case.
You have to compile from sources, like:
* https://kamailio.org/docs/tutorials/5.4.x/kamailio-install-guide-git/
Debian packages from branch 5.4 are also built over night:
* http://deb.kamailio.org/#dev54
Cheers,
Daniel
