[Freeswitch-users] NOOB QUESTION - Remote Extension Routing

[Shawn Lewis]

I have a number of remote extensions connecting to my server. After some 
research I was able to get them register by creating a "doublenat.xml" 
in the sip-profile.

So now I have users being able to register.  Though in the examples I 
saw, the sample for being able to extension dial from an internal 
registered phone to them is not so easy, and that is where my question is.

So I have extension 1001 registered locally.

I have extension 2010 registered remotely.
I have extension 2011 registered remotely.

2010 and 2011 both come from different locations.

In my default.xml dialplan, how would I setup being able to dial 2010 or 
2011 without KNOWING the IP address of their gateway?

I have tried sofia/doublenat/2010 - doesnt work
I have tried sofia/doublenat/$1%$$x.x.x.x  - where x.x.x.x = my extern 
IP - doesnt work
I have tried a manual sofia/doublenat/2010 at x.x.x.x = where x.x.x.x = 
their NAT GW, and that does work

But I will not always know their GW address........

Thanks
Shawn
