Hello,
Jesus Rodrigues and Inaki Baz Castillo changed their work roles a while ago, so they no longer deal with Kamailio and they do not expect to do it in the near future. To keep the Management group with members connected as much as possible with the project, Fred Posner and Victor Seva were proposed to replace them.
For the new members in the public lists: the management group of Kamailio is not involved in the daily development or administration of the project -- all those are done on public mailing lists or kadmin group (internal infrastructure administration) -- management team is supposed to take the decisions on sensitive situations for the evolution of the project.
Should anyone have opinions about these changes, let's discuss on sr-users mailing list.
Cheers, Daniel
