Odd 7960 rebooting problem

Dear Group,
~ I've had two 7960 units connected to my asterisk system for
several months -- everything's been working fine, no complaints..
Something odd is happening now, though. Both 7960's will crash and
reboot, about half a second into a call once the call is officially in
progress.. I was wondering that maybe since I've been fiddling with
my routing tables that possibly I've managed to firewall off rtp
between the phones and the server, but I don't think that's the case
since the sip packets do appear to correctly start the call...

Does anyone know why phones would just, out of the blue, after several
months of working fine, synchronously start rebooting? Is there some
magic that cisco does that says "Hey, your license is expired and you
can't use this phone anymore until you renew!"

If that's the case, if someone can direct me to the persons I should
contact at cisco to purchase licenses I'd appreciate it -- I got these
two units from ebay.

Thanks,
Peter Grace

What software are you running?

I've never really noticed anything quite like that, are you
using the latest asterisk cvs, or 0.5 release ?

you are aware and upgraded your devices and asterisk for
the sip security stuff earlier this year I presume? :)

Jared,

The phones are running SIP 4-04-00 -- I tried downgrading the
software a few releases then upgrading back to 4-04 but the same
problem persists. I'm concerned about going to binary-signed 5, since
someone told me to do that to my last phone (which was having a
different reboot problem) and it essentially just turned the phone
into a $350 paperweight. What is the SIP security stuff from earlier
this year? :) I was running a previous version of asterisk in CVS, and
even updated to the latest CVS version, but the problem still happens...

Thanks,
Pete

I believe the signed binaries are to prevent the phone from
becoming a paperweight. First, it's not like someone else is going to write
software for the phones besides cisco. Second, since they use TFTP
which is a very easy/insecure protocol for fetching its software/images,
this actually will prevent the loading of a corrupted (ie: non signed)
binary on the phone if your tftp server files are damaged, or if
there is a data corruption problem while fetching the image.

I would recommend going to 6.0, I've seen no problems with it
in our environment, it fixes a lot of problems that were in the 4.x
series and provides new features that work well with asterisk.
Since the support on the phones is something like $8 /yr, you may
want to look at that.

As far as the SIP security advisory goes, please
see this: http://www.cert.org/advisories/CA-2003-06.html
