My experiments show that with ``` modparam("nathelper", "ping_nated_only", 1) modparam("nathelper", "sipping_bflag", FLB_NATSIPPING) modparam("usrloc", "nat_bflag", FLB_NATB) ``` when both FLB_NATB and FLB_NATSIPPING branch flags are set, no OPTIONS from Kamailio to UAC is generated, so I assume that nathelper.ping_nated_only=1 does force 4-bytes UDP keepalive. This change spells the above, as the behaviour currently is not specified.
