Klaus, Thank you for this detailed explanation. This is essentially what I figured was happening. I was able to use htable to work around it.
I guess however I am still confused as to where there is any public documentation on this specific bit. Had I've not been working with Kamailio for years I would think this would confuse others. Let me know if it is somewhere else, otherwise I will add it to the Kamailio wiki.
