Please decide on this Pull Request. I did some *serious research* and removed buggy / overlooked cases for IPv6, while not altering the code for IPv4. Nobody seems to be questioning that, and yet it has stalled?
The original code that I changed was not very good to begin with, but nobody appears to be motivated to fix it for IPv4, which apparently is *good enough*. For IPv6 the current code is *unacceptable* and that is fixed by this Pull Request. So, please accept this as **the best option available** -- the alternative is worse, namely doing nothing and continue with broken support for SIP over IPv6.
Also, this is my first bugfix, I invested seriously by studying Kamailio and exploring the options. I also depend on SIP over IPv6, and generally believe it should be a serious option for all. I have other ideas to extend/improve Kamailio with a few neat modules, but this indecisive handling makes me too nervous to seriously undertake further effort.
