asterisk users - Sep 2005 - Asterisk and a SPA3000 behind NAT peer registration

Hi,

        I have a little situation here :( Perhaps somebody can give me a 
hand with it.

        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!!!

Don't bother with the peer.

Define both the Line1 and PSTN ports on the SPA to register with asterisk
using different UserID/Passwords for each, use port 5060 for one and 5061
for the other, and in asterisk's sip.conf file define them as type=friend.

It does work just fine that way.
