There's one thing that could happen: Calls that get cancelled after a restart, could possibly keep on ringing on the far end. At least if you check for an active transaction in your kamailio config.
if (!t_check_trans()) { sl_send_reply("481", "Call/Transaction does not exist"); xlog("L_ERR", "CANCEL: found no matching transaction F=$fu T=$tu R=$ru\n"); return; }
And if you do some sort of random dispatching, CANCELs could end up on a different gateway.
But other than that, a restart shouldn't cause much trouble. Especially in-call requests get routed by Route headers only.
