Is Comcast (a) having routing issues, or (b) renewing your DHCP lease to
a new address?

Comcast here only assigns a new WAN IP if the MAC address changes, if the cable modem has been off for a very long time, or, as is most often the case, their network geeks decide to muck around with things. Often on a Sunday afternoon, but not always. Sometimes their DNS servers seem to go out to lunch for a short period. Asterisk really doesn't like that either

The latter is in fact a blatant violation of the DHCP specification, but
it doesn't stop them from doing it.

Every time you reboot, check if your IP address has changed...  I'm
betting it has.

I know it is not Astlinux related but I was wondering if any of you experience 
this issue.
I run my Soekris net4801 on Comcast broadband and once in a while I find all my VOIP providers 
"UNREACHABLE" when I do a "sip show peers"
I recognize that my broadband can go down once in a while but the asterisk should 
reconnect back to me 3 VOIP providers... All 3 of them are unreachable and I can see in 
the logs trying to connect back. I tried the reload and tried to stop and restart the 
asterisk service in /etc/init.d/asterisk "stop | start" but won't do it.
Rebooting seems to always do it for me and have everything get back online.  I 
don't have any weird firewall rules on my Linsys router running Tomato firmware.
Is just kind of weird if you ask me....
Meanwhile I wrote a quick crude script and put it on the crontab to reboot my Soekris box when the VoIP service is unreachable....
#!/bin/sh
asterisk -rx "sip show peers" | grep teliax |grep OK|wc -l > /tmp/log
VAR=`cat /tmp/log| awk {'print $1}'`
if [ "$VAR" != "1" ]
then
/sbin/reboot exit;
fi


Any ideas what's going one here guys?

Thank much....
