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

My sip_profiles/internal.xml and external.xml have these lines:
<param name="rtp-ip" value="$${local_ip_v4}"/>
<param name="sip-ip" value="$${local_ip_v4}"/>
<param name="ext-rtp-ip" value="auto-nat"/>
<param name="ext-sip-ip" value="auto-nat"/>

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:

Hope this helps.

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.

Well, it must be operating by F.M. here because I never enable UPNP and checking this UBNT EdgeRouter-X it shows zero packets handled by UPNP2.

I must’ve stumbled upon a working configuration by chance, since I’ve never fully understood the ACL system in FreeSWITCH. I’ll have to do some more experimentation.

Thanks for clarifying.
