That only works if you have a NAT-PMP / UPNP router, for the ext-*-ip options, you can put your public IP in like "autonat:1.2.3.4" and set the local-network-acl and it will use that local-network-acl to determine when to use the external IP or internal IP. /b On Fri, Aug 20, 2021 at 2:10 PM Bote Man <botelist@gmail.com> wrote:

which magically "just works" between internal extensions as well as with a couple cloud SIP providers. This is with FreeSWITCH version 1.10.5 from about a year ago.
Maybe try those settings and see if they help?
BTW, I fell in love with FreeSWITCH when I installed it and configured a couple phones that were up and calling each other in my lab in about 10 minutes, so you shouldn't be too far off. They've really tried to make it easy to get a working system going quickly, then you can break things from there :-)
Here are my ancient notes which might also be helpful:

Hi.
I have just installed my first FreeSwitch server on a virtual machine on my local network, and I'm playing with it and a couple of SIP phones on the same network, in order to learn about it.
I've got the phones to register to the server (I've changed the default password in vars.xml), and my first test is simply to place a call between one phone and the other.
I've discovered the "NAT feature" of FreeSwitch, where it finds out what the *external* IP address of my Internet router is (which has nothing to do with the FreeSwitch server or the phones I'm trying to work with here), and starts presenting that address to the telephones in the Invite messages (inlcuding the SDP negotiations).
I've found https://freeswitch.org/confluence/display/FREESWITCH/Auto+Nat and https://freeswitch.org/confluence/display/FREESWITCH/NAT+Traversal which tell me that I need to use the "-nonat" command-line option to freeswitch to disable this.
However, this doesn't work for me:
# ps ax | grep freeswitch 3678 ? S<Lsl 0:02 /usr/bin/freeswitch -u freeswitch -ncwait -nonat
sofia status profile internal
================================================================================================= Name internal Domain Name N/A Auto-NAT false DBName sofia_reg_internal Pres Hosts 192.168.32.59,192.168.32.59 Dialplan XML Context public Challenge Realm auto_from RTP-IP 192.168.32.59 Ext-RTP-IP 198.51.100.21 SIP-IP 192.168.32.59 Ext-SIP-IP 198.51.100.21 URL sip:mod_sofia@198.51.100..21:5060 BIND-URL sip:mod_sofia@198.51.100.21:5060;maddr=192.168.32.59;transport=udp,tcp WS-BIND-URL sip:mod_sofia@192.168.32.59:5066;transport=ws WSS-BIND-URL sips:mod_sofia@192.168.32.59:7443;transport=wss
As you can see, my public IP address (represented here by 198.51.100.21) is still there, and it's still getting included in the Invite message and SDP negotiations between my telephones.
So, how can I run FreeSwitch and two SIP telephones on a single internal network, without any reference to my public IP address?
Thanks,
Antony.
