[Freeswitch-users] sofia - wrong (external) IP address in contact for local calls

Tue Jun 11 22:24:54 UTC 2019

local-network-acl was (by default) set to localnet.auto which
correctly detected my LAN subnet

freeswitch at deb9> acl 192.168.0.66 localnet.auto
true

so I didn't have high hopes for this working, but I tried it anyway.
Created a new acl called mylan with 192.168.0.0/24 allowed and used it
for local-network-acl,

freeswitch at deb9> acl 192.168.0.66 mylan
true

...
2019-06-11 23:24:40.764885 [DEBUG] sofia.c:4641 local-network-acl [mylan]
...

no change, it's same as before.
