There are several IRC channels at irc.freenode.net, and one focused on Kamailio where you can meet the Kamailio Project users and developers, chat with, post questions or, even better, answer them. Many developers are on European time zones, so consider that if you need to reach one. If you do not get any comments or answers, please use the mailing lists.
