You need to make sure you setup the user directory correctly. http://wiki.freeswitch.org/wiki/FreeSwitch_XML_User_Directory_Guide My earlier email provided a precise example and warnings about making sure the tags etc match up. When you setup the <domain> tag in the directory you must make sure there is a domain tag that has the same name as the host portion of the to: header in the register. Using forensics from your traces here is the exact domain tag to use in directory.xml with 1 caveat: ----------------------------------------------------------------------- **replace the string 1234 with the password you specified in the ata** ----------------------------------------------------------------------- *NOTE* normally $${domain} would be ok here as the name assuming that the domain variable is set in freeswitch.xml but I put the exact domain name to avoid confusion. *ALSO NOTE* You can comment the password param if you want it to accept any password for this user. <domain name="freeswitch1.asnetinc.net"> <user id="homebase"> <params> <param name="password" value="1234"/> </params> <variables> <variable name="force-contact" value="nat-connectile-dysfunction"/> </variables> </user> </domain> I ask that if you get this working you please document this on our wiki in exchange for this exhaustive description of what you need to do.

ok how about this:
try rev 5207 and do everything I described before only in the force-contact set it to nat-connectile-dysfunction
<variable name="force-contact" value="nat-connectile-dysfunction"/>
This will rewrite the host and ip of the contact to use the ip and port the req was received from. To benefit from this feature, you will probably need to set the ata to constantly register to maintain this dynamic reverse mapping created by the nat routers. Most of them will destroy any mappings with inactivity after a certain period of time so you must make your reg freq more often that that time period whatever it may be.

Hi Anthony,
I assume that means we can change the topolgy to something like this: ATA<->NAT<->Internet<->FS1
Basically, what we're doing here is telling FS1 how to find ATA. There are only two problems: 1) NAT is on DHCP. (I assume this can be worked around by using DynDNS instead of an IP.) 2) As I discovered while looking for the mystery 10.0.0.221 IP, NAT is actually two NATs, one behind the other, and I only have access to one of them.
While you're at it, why don't you just make an option (<variable name='my-ata-sucks' value='true'/>) to totally break RFCs and mimic Asterisk's treatment? :-)
Thanks a bunch for all your help, - Dave

Hi,
You sound like a good candidate for my new experimental force contact feature.
For this to work you need to use the directory for auth instead of the blind reg mode.
*) Edit sofia.conf.xml and comment the blind reg option. *) Edit directory.xml and add a <user> tag to the <domain name="$${domain}"> section making sure $${domain} is also the name of the domain portion of the sip's client registration.
edit the file to look something like this and put in a absolute contact to use when this user registers regardless of what he advertises. This means that if you are using nat you should setup a permenant port forwarding for whatver uri you mention.
e.g.
Assuming your public ip is 66.2.2.2 and your phone is 10.0.0.2
add a rule to always port forward udp port 5555 of 66.2.2.2 to 10.0.0.2 5060 then edit the following so the contact uri is user@66.2.2.2:5555
Whenever the phone registers with this user the specified contact will be added to the database instead of the real one this should make it possible for your phone to receive sip traffic even if it does not support STUN.
<domain name="$${domain}"> <user id="myuser"> <params> <param name="password" value="mypass"/> </params> <variables> <variable name="force-contact" value="[TESTING] sip:myuser@66.2.2.2:5555"/> </variables> </user> </domain>

Hi guys,
I've got a rather interesting situation, here. I've got an ATA registering to a FreeSWITCH(TM) (FS2), both behind NAT. So far, so good. Now, the FreeSWITCH(TM) registers to another FreeSWITCH(TM) outside the NAT (FS2), and that's where the problems start. Here's the configuration:
ATA<->FS2<->NAT<->Internet<->FS1
ATA: 10.1.0.51 (behind NAT) FS2: 10.1.0.30 (behind NAT) FS1: freeswitch1.asnetinc.net (64.118.94.19)
Now, here's where it gets very interesting. This is what FS1 gets when FS2 registers:
From: [R352928@freeswitch1.asnetinc.net] Contact: ["user" <sip:R352928@10.0.0.221:39260>] Expires: [3600] nta_agent: tport: Bad message
Now, where on Earth did 10.0.0.221 come from??? (I've actually hardcoded both external_rtp_ip and server_name to the public IP of the NAT in the FS2 config, but for some strange reason, FS2 apparently claims to be at 10.0.0.221, which isn't even its local IP.)
As if that's not interesting enough, I get this from FS1, too, when it tries to connect to another SIP server on the public Internet:
outbound(0xb4e1e1a0): detected NAT: freeswitch1.asnetinc.net != 64.118.94.19
Now, since a forward DNS resolution claims that the inequality is false, I assume it attempted a reverse DNS lookup, which would fail (since my ISP takes forever to update PTR records).
As usual, any hints, tips, tricks, ideas, suggestions, flames, questions, or (ideally) answers are greatly appreciated :-)
Thank you, - Dave
