I'm going to resurrect this as I've noticed that opensips 2.4.6 sends CANCEL for branches it never got a provisional response for. Was this changed intentionally?
Also, it looks like the discussion I am responding on was about opensips 1.5 but if any testing is needed around fail-over scenarios I expect to be doing some of that over the next few days. Just let me know what still needs to be looked at and I'll try to get it in.
