Hello,
I'm new with Kamailio. I've just setup on Debian Squeeze using mostly the
example configuration.
I've been able to route inbound / outbound call on local networks W/O NAT
and over mobile 3G+NAT ...
Unfortunateley I've tried over 3 wifi / local + NAT and Kamailio drop call
and return me this message "SL local ACK found -> dropping it! error ..."
My Kamailio server has public fixed IP and listen on 5060:udp
It's look and issue with NAT setup ... How can we solve it ?
Best regards

You'd need to post the SIP capture, but it sounds like Kamailio is not
associating the ACK with any known transaction, perhaps because the
ACK has an unexpected RURI, Via branch parameter, or CSeq number.

To clarify: technically, ACK is a separate transaction. But
end-to-end ACKs are associated with the TM state machine, which means
Kamailio is supposed to know what is being ACK'd.

Maybe it is a message from sl module due to a stateless (sl) reply. But
for sure strange. IIRC sl reply haev a certain via tag which allows sl
module to identify corresponding ACKs and absorb them before entiering
the routing script.
