I'm using Digium Phones.
I still do not understand why it's not possible to do it the way the networks are right now.

If the options I mentioned in my sip.conf are enough, then both phones should use Asterisk as a proxy, and Asterisk should handle all the media.

I will run tcpdump traces tonight and will check it out.
My router has a bug and won't let me mirror port. From tech support I need to reflash it. I'll do it and try it again.

    Or if it's just a couple phones, you might be able to setup a vpn
    connection directly on the phone itself - have it vpn into 'HQ' and
    get an address on that network.  I'm not sure which phones you're
    using though or what phones support that setup.

    I don't see how that would really solve anything - instead of the
    server sending the 192.168.x.x packets onto the local network, it
    will send them up toward the internet and get black-holed.  What
    probably makes more sense would be to switch the subnet on one of
    the networks, AND put up a vpn between them, adding the routes for
    the private networks to cross thru the tunnels.

    I thought about that.
    I will give it a shot tonight and will post back my results in here.
    Thanks

    It will allow me to deploy more phones in separates buildlings in
    the future. If I do the IAX solution, it means that for every
    building, I need a box..
