Ok, I posted previously asking how to figure out the registered endpoint
of extensions registering. I used the doublenat.xml sip profile
solution, then applied the following the dialplan:


<extension name="public_extensions">
<condition field="destination_number" expression="1010">
<action application="set" data="dialed_ext=${destination_number}"/>
<action application="set"
data="contact=${sofia_contact(doublenat/${dialed_ext}@X.X.X.X)}"/>
<action application="bridge" data="sofia/doublenat/${contact}"/>
</condition>
</extension>

where X.X.X.X is the EXTERNIP, calls now ring the outside extension, but
get no voice/rtp.

I have enable the proxy-media setting in my double-nat profile as well.

What happens is the internal extension dials external NAT'd extention 2001.

sofia passes my extrernal IP and PORT successfully in the SDP of the
Invite to the remote extension.

I receive my 180-ringing.
I receive my 200 OK when answered, in the SDP of the message it is
providing the 192.168.1.5 address of the IP telephone.

So now FS starts to send media from my IP to 192.168.1.5........ of
course which will never reach endpoint registered phone...

Here is my doublenat.xml in my sip_profiles, am i missing something?? I
would think FS would know not to send there.....
