Hello.
I was wondering if someone can help me with some problem that I’m having
with the combination of FreeSwitch and Kamailio as SBC.
I’m having and ACK not routed by kamailio and dropped.
Here is the debug.

When I removed Freeswitch from the path the ACK is routed ok.
The ACK is routed by loose_route, but then it fails because the

What could be happening?
