Suggests to replace Cisco 7965 phones 2

[slp123]

CISCO CUCM 10.5; UNITY 10.5 with Cisco 7965 phones.
We have 3 sites with CISCO 7965G phones purchased in 2010.
Over the years occasionally when a phone was relocated to another station the phone crashed.
They start to go through the cycle then get stuck with the green speaker button on. They can't find the IP address.
When we upgraded to 10.5 recently we lost 28 phones.

Have other experienced this?

Suggestions: The 7965's were very user friendly and recently I purchased some Cisco 8851 which are not as intuitive.
Looking for suggestions for other model phones that the Cisco group are using.

We have same problem with dozens of CP7945. Couldn't find solution for this problem. In our case even the display is off. The green speaker button on and nothing more. Monitoring the line shows nothing, as if no phone is connected.

Ours start the registering process with lights blinking down the lines and once it gets to the speaker button the registering ends. Green light on and phone has crashed; it will not continue registering. Nothing appears on the screen; we cannot get these phones working again. Previously it happened in some cases if the phone was moved to a new location; or during our upgrade we lost a group of them. Recently we lost 4 phones for simply no reason at all. Person on vacation returned and phone had crashed; one used phone in the morning and as sitting at desk his phone crashed!

Some of these sound like the Cisco memory fault affecting a lot of the product lines.

"Problem Description

IP Phones (listed in the Products Affected section) might fail to boot up after any power cycle event on the phone. This can be from a power cube, Power over Ethernet (PoE), or a recycle of the access switch while PoE is in use.

Phones that fail remain in a stalled boot-up state where the LCD is blank and the speakerphone lamp is lit. The phone will no longer recover back to an operational state."

The phones are not repairable at that point. Submit an RMA.

Thank you. That definitely is the issue we had then.
Going forward we pay for 5 year extended warranty when purchasing new 7965's.

We have a one day power down at one of our sites building in 2 weeks and of course we are concerned that 10% of our 7965G / 7945G phones may fail due to the losses we have had.
Any thoughts?

Not sure if it would be beneficial to unplug all sets prior to the shutdown and plug them in after. Any thoughts on whether that would reduce the amount of disruption and loss?
Any thoughts would be helpful.

It is an issue of luck. The only thing you can do is not to move the units from the present locations and also not to make any upgrades when power will be back, as the problems may occur while the phone is in reset process or while boot up.

The link was most helpful!
Lots of interesting information there about the faulty memory component issue.
Thank you to all.

seen it on the 7970's too, we have a net agreement, so off they go.
I don't care for the new phone either. Just not as nice.
