Jared,
the Portech SIMbox is registering to a DNS name. The firewall is off and
the NAT is a Zyxel NBG-419 router.
No mather what port I set, It is not working :
<--- SIP read from my_public_ip:5070 --->

Is it normal that there is a Via-header sent from the SIMbox with its
local IP-address in it ??
Is it normal that "SIP read from my_public_ip:5070" has the same port
number as the SIP-account (simsim1) 192.168.1.25:5070 ??
Could it be that NAT is not working correctly in my router ??

Is the device registering to an IP address, or do a DNS name? What type
of NAT firewall are you using?
This reminds me of a problem I had years ago with a Cisco PIX firewall,
where it would rewrite IP addresses in the SIP Request URI, causing the
authentication to fail. One solution was to have it register to a
fully-qualified domain name instead of an IP address, so that the
Request URI wouldn't get overwritten.
It's certainly worth a shot...
