Maybe you could get a sip trace on the 3cx dialog and compare it to the FS dialog and see what's different. You can put those up on <a href="http://pastebin.freeswitch.org">pastebin.freeswitch.org</a> and put the link on this thread.<br>

Hi,<br>
<br>
I have a remote extension( Cisco SPA504G ) that connects to our<br>
FreeSWITCH server across the internet. I am using a typical double nat<br>
scenario as per wiki and the remote extension registers properly<br>
against the right profile.<br>
<br>
The remote extension via a dialplan can dial any of the extensions<br>
that are local to the FS boxes network successfully with no problems<br>
<br>
However when we dial out to the remote extension we get a "Cannot<br>
locate any authentication on credentials to complete an authentication<br>
request for realm '<our external domain>'<br>
<br>
I have tried using both the default force register options and also<br>
setting up another directory realm as well.<br>
<br>
When looking at the log you see the originate attempting to connect to<br>
the appropriate ip/port of the external phone, but after it "entering<br>
state [calling]" it fails with the above error.<br>
<br>
Just to test I have installed the 3cx softphone client on the remote<br>
network, and it can be dialled with no problems.<br>
<br>
The difference being that the 3cx seems to register a port in the<br>
dynamic range (eg 52789) where as the cisco phone uses the 5090 port<br>
<br>
Has anyone struck that issue before<br>
<br>
Thanks<br>
<br>
Bob<br>
