If FS is not behind NAT, then every call generates at least three
INFO-level log messages:
[INFO] switch_nat.c:589 NAT port mapping disabled
This is useless noise. The message is only interesting if you do have
NAT enabled but mapping disabled, which might indicate a configuration
issue.
With this change, we just skip the entire nat_add_mapping function if
the NAT system isn't initialized or we're not behind NAT.
switch_status_t status = SWITCH_STATUS_FALSE;
switch_event_t *event = NULL;
+ if (!initialized || !nat_globals.nat_type) return status;
if (!nat_globals.mapping) {
switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_INFO, "NAT port mapping disabled\n");
return status;
