Hello,
I couldn't resist to comment on some lines here.
First of all, if you enable keepalive from the sip proxy to
the phones (both SER and asterisk can do that) the state
from server to phone won't be expiring. That way it is also
not true that SIP is not well suited for firewalled
connections. I

The SIP-Phone sends every 25s (default) a keep alive message to the SIP-Proxy
to remain the state on the NAT'ed Firewall. So I have to lower the

The state is not expiring immediately.
If I then delete the state, the SIP-Phone registers immediately with the

Hi,
My ISP upgraded the cable modem to the DOCSIS-Standard. Since then, the
IP changes every 4 hours. Before, I received the same IP for more than
a year (the box is always running).
The setup is a Soekris box attached to the cable modem on the first
interface, and on the second interface (NAT'
