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.

Sebastian
