[SR-Users] ACK on Reverse Invite is send to NATed Internal port instead of public port

26 Jan 2023

Hi,
I am having an issue on some outbound calls from nated UAC. On these calls
our SBC receive reverse invites from the carrier side within the call. When
this happens, my SBC(Kamailio1) sends the invite to UAC and the UAC sends
200 OK (SDP). Unfortunately my SBC(Kamailio1) sends back the ACK not to the
correct UAC public port but instead to UAC internal port making the call to
crash!
My setup has: (TLS)UAC -> (UDP)Kamailio1(UDP) -> (UDP)Kamailio2(TLS) ->
Carrier(UDP)

Bellow you can find the trace and you can see the ACK send to wrong port
on 2023/01/26 09:48:31.254591

Your help will be much appreciated!
