asterisk users - Aug 2005 - Asterisk -> Sipura SPA3000 peer behind NAT

Hi,

        I have a little situation here :(

        I have an Asterisk working, and in another office, a Sipura SPA-3000.
        I configured the SPA and I have the extension working, the incomming
trunk working, but the outgoing trunk (peer) does not work.

        The issue is that I have a dynamic IP where the SPA is, and neither the
SPA nor my router have DynamicDNS.
        So, if I manually change the host for the peer for the SPA PSTN Line,
then everything works fine, and I can make local calls through it.
        BUT when my router's IP changes... I am lost. (EVEN while the
extension SPAN Line 1, or the incomming trunk are registered and DO work.)

        According to what I read, if I setup the outgoing trunk to type=peer
with host=dynamic, then I can make the peer to register itself into the
Asterisk, so the asterisk will know where to contact the peer.
        But.... I cannot figure out how to make the SPA register as the peer? I
can make it register as a type=friend for the incomming traffic, but not as a
peer..

        The Line 1 part of the SPA is registering and working neatly.

        BTW I have Asterisk@home  

        Any idea, suggestion, or whatever you can think about it?
        Thanks!!!
