This is why patch should be released..  Did you send me your partysip's
patch once?

At least, can you send me your initial patch? I'll be very busy till
the end of the year. I would love to get a new patch from you so that
I can get ipv6 support sooner.

I think libosip's parser already support ipv6 address. Did you experience
any issue?

Thanks
