What he is saying is that the router at the customer's site is messing up the SIP contact header, possibly by putting the wrong IP address in it. You best bet is to have the customer log in to his router and disable any SIP ALG. Alternatively you can try some of the NAT settings in the SIP profile. For example you can set "aggressive-nat-detection" to true and see if that helps, although you may need to test your other customers to make sure that setting doesn't break their connections!

Don't you just love broken NAT devices? :)

OK, here is what I use.

 

In the sip interface profile of FS I have

      <param name="nat-options-ping" value="true"/>

      <param name="ext-sip-ip" value="auto-nat"/>

      <param name="ext-rtp-ip" value="auto-nat"/>

 

I just downloaded xlite and used defaults plus account credentials fine.

 

Did you address the problem with their router?

I had this error last night!  The problem is with the router/nat at your
customers.  It is not including its IP/Domain in the header.  I had to set
my particular router's ALG to ignore/passthrough SIP ALG.  Many routers only
allow ALG on or off.  You want off.

But, you need to configure for NAT on your clients and FS.  If your FS
server is LOCAL to where you "setup extensions in FreeSwitch" there is a lot
still to configure.  Let me know I will tell you what I know about that.
Also, what is the phone or ata brand being used?
