Hi ! It's really nice option - that now Opensips nodes can replicate "SIP registrations" and "Dialogs" between each other w *"bin_listen" options. http://www.opensips.org/Documentation/Interface-Binary-2-1 * I have a few question related to cluster architecture with fail over: 1). - If one of the "Opensips phone edges" was restarted - can it catch all USRLOC registrations throught binary interface from alive nodes ? - if it can't do restoring of the database through binary interface - maybe you have an idea how to do that ? 2). - it's share dialogs information - if one node is suddenly down, can call dialog be proceeded on other node ?
