[cisco-voip] Cisco IP Phone Top Buttons Flashing Green, Amber, Red

[Ryan Ratliff (rratliff)]

Resurrecting this because we are finally making progress.

It appears that root cause on this is a script that the phone runs when it fails to load the MIC. If you get a PRT or ssh into a phone with the lights and run “show cpu” you’ll see a process running called mic_err.sh (this command is logged in the show-output file in the PRT).

I have a request for anyone that has had one of these blinking phones in the past that and fixed the blinking by upgrading the phone.
Can you reboot that phone and pull a PRT?  You can send it to me directly. I want to verify if the phone was able to load the MIC when it booted.

All we know so far is that this mic_err script makes the lights blink, a phone that gets them stuck that way needs to be replaced via RMA, but I don’t have much data on a fixed phone.

Thanks,

-Ryan

I just filed CSCve49657 to track it.

If anyone can get a PRT from a phone that’s doing it (preferably right after a boot) please send it to me directly or work through TAC.

Well, moving to the following did fix the flashing lights by the way.

Active Load ID: sip88xx.11-7-1-17
Inactive Load ID: sip88xx.11-5-1SR1-1

I then flipped the phone back to 11.5(1), and the problem did not return, so the upgrade to 11.7(1) permanently fixed the issue.

So, no documented defect for this then Ryan, is that right?

FYI I also posted my experience in the forum posting for future Googlers.

I can see a few cases on it, some are just RMAs and others are fixed by an upgrade.

If anyone has one that’s not getting fixed by an upgrade get a case open and let me know the SR number. We will probably need to get it sent to us for debugging.

I'd like to have some official documentation from Cisco explaining that they know their phones do this and what the course of action needs to be.

I (personally) had never heard of this before your email this morning. I am now aware that this is a problem observed by a small number of customers (the number of cases I can find is somewhere between a peck and a bushel) and the official course of action needs to be open a TAC SR fur further investigation.

Can someone confirm whether or not this issue linked below has been filed as a defect please?

I don't have an active SmartNet contract on my phones (like most people, I'm sure) and so I cannot open a TAC case for it.  I'd like to have some official documentation from Cisco explaining that they know their phones do this and what the course of action needs to be.  So far, this forum posting is all I have found; though I'm no bugsearch ninja.

Thanks.
