Hello,

Is there any chance that you can test with 5.0 or 5.5? Just to rule out if
there is an issue that was already fixed. These are the two stable series
maintained at this moment.

Otherwise, open an issue on tracker at github.com/kamailio/kamailio, I was
rather busy lately and this can end up being forgotten.

Cheers,
Daniel
