RE: [Asterisk-Users] Cisco 7960 lockups - any experiences?
Paul -
Yes, your description is correct.
- moving the phone (no ethernet passthrough) results in no symptoms
- testing at the same location with no ethernet passthrough is not
possible during "real" traffic transport, since there's only one
ethernet in that cube
- comments about pingfloods: there is minimal traffic on this
network, and no pingfloods or other data directed at the Cisco phone.
Other phones of identical configuration on the same subnet/collision
domain/switch show no symptoms.
Interestingly, there was a followup post that talked about cell phone
radiation causing lockups on the poster's 7960. There was an old
AT&T 7406 Plus phone located _directly_ next to the 7960 in question
in my circumstance. I have since moved the 7406 away from the 7960;
let's see if perhaps that is the culprit due to spurious RF
interference.

If you move the phone somewhere else in the office, without the PC, it
doesn't freeze? Does it freeze when it's in the same location, but the PC
isn't plugged into it? That is, does this happen only when a PC is plugged
into the phone?

Subject: [Asterisk-Users] Cisco 7960 lockups - any experiences?
This is almost certainly not an Asterisk-specific posting, but due to
my inability to find a VoIP-focused Cisco list, I'll post here in the
hopes of finding a more diverse user community.
I am using a Cisco 7960 (version 6.0 SIP firmware) with Asterisk, and
have been experiencing situations where the phone locks up. "Locks
up" means that the bottom part of the screen ("Your current options"
and the redial/newcall/cfwdall keys) disappears, and all keys on the
keypad are non-functional except for the *-6-settings reboot keys.
Previous software (4.4) exhibited the same symptoms. I replaced the
7960 with a brand new 7960G, thinking it was bad hardware. Same
symptoms. I replaced the power supply, thinking that perhaps could
be the problem Same symptoms. I upgraded to 6.0. Same symptoms. I
replaced the ethernet cables. Same symptoms. I invoked an ancient
curse-removal spell involving chicken bones and eye of newt over the
phone. Same symptoms. A phone elsewhere in the same office (same
switch, etc) works with no problems, but does not have a PC hooked to
the 'PC' ethernet port. In fact, the first 7960 I tried, with the
swapped out power supply, works well elsewhere.
I have used 79xx boxes in many circumstances, and all have performed
admirably. However, I rarely have configured them so that a PC is
connected to the other side of the device. The PC is running Windows
XP, and sees mild SSH/email/web traffic. I cannot say if there is a
correlation between traffic volume and failure intervals; I have no
data.
The only thing that remains the same is the PC on one side, and the
switch port on the other. Previously, the PC attached to that switch
port had worked without any problems for quite some time before I put
the 7960 in place. Even if the problem is the PC or the switchport,
a failure or malfunction on one of those two components should not
cause the phone to malfunction. If it is a problem with the 7960
pushing traffic across the tiny built-in switch, then we have a real
problem on our hands that Cisco had better fix, pronto.
I would appreciate reports of others as to similar issues or
resolutions which they found effective.

RE: [Asterisk-Users] Cisco 7960 lockups - any experiences?
I noticed that on earlier versions of the firmware I was able to crash these
phones with a flood ping (ping -f ). I send this notice to Cisco
but never followed up on it. How are you powering this phone, POE or wall
cube?

Hello John,
I have a similar story with one of mine..
If i use a cell phone near it, it reboots :) The other ones are fine.. I
think it's a hardware problem, but it only reveals itself with the cell
phone radiation :>
