New subject: [kamailio/kamailio] Support for 192.0.0.0/29 as NATed source (#1488)
It's been a while, stumbled on this case just now. It seems like either nat_uac_test()
or more likely fix_nated_sdp() doesn't catch the 192.0.0.0/29 subnet as private.
**Script logic:**
route[NATMANAGE] {
...
if (nat_uac_test("8"))
fix_nated_sdp("15");
...
}
