Cisco CP 8851-3PCC 2 Upper Line keys blinking green yellow red

Hi all,

 

My CP8851-3PCC phone can't register as asterisk extesion, after submitting changes phone reboots and begins key blinking. I try to reset it to factory defaults, but after reset on first time boot phone requires activation code.

There was installtd 11-0-0MPP-7 firmware. I upgrade it to 11-2-3, and then 11-3-1, but without any luck.Another phone (same model) works good with this Asterisk server.

When I check status with identical configuration, I find only 1 difference -

Client certificate: Not Installed

Please, help how can I resolve the issue.

Thanks in advance.

Hi,

Can you try below hard factory reset procedure:

Step 1

Remove power from the phone in one of these ways:

  • Unplug the power adapter.
  • Unplug the LAN cable.
Step 2

Wait 5 seconds.

Step 3

Press and hold # and plug the phone back in.

Step 4

When the Headset and Speaker buttons are lit, release # and enter the following key sequence:

123456789*0#

The light for the Headset button turns off after you press the 1 key. After you enter the key sequence, the Mute button lights.

Caution 

Do not power down the phone until it completes the factory reset process, and the main screen appears.

The phone resets

Hi, 

What it the Hardware Version of the phones you have?

Info --> Status --> Product Information. 

So you have two 8851, one of them does not have the certificate installed? Is that correct? 

Please share the hardware version for both. 

 

Thanks

Both hardware versions are V01.

But client certificate installed int only one of them.

Also, activation code requires phoe, which does not have client certificate.

So the phone which have the lights flashing is the one with no certificate installed?

Hi

I also have a 8851 here which I've been running tests on and it looks like you might have a phone a corrupted Manufacturer Installed Certificate (MIC). 

If that happens, the phone will display the certificate status as "Not Installed". 

If you look at the logs you will see something similar to:

0147 WRN Nov 13 02:13:56.497328 (883:883) voice-SSL_Init_Task continuing SSL initialization with no MIC

 

My advise would be to contact your Cisco rep or TAC to get this phone looked at. Maybe replaced. 

 

Thanks
