T58A red light flashing
Hello,

my T58A has a red LED blinking all the time, but I have no idea for what reason! The phone doesn't show any warnings or messages on the screen.
Any suggestions?

- the only active SIP account is registered
- the default password is changed
- no missed calls or voice mails
- current firmware

Hi,

The Power LED indicator indicates power status and phone status.

You can configure the power LED indicator behavior using the WEB UI in the following scenarios:
Switch the Power LED indicator On or Off
The IP phone receives an incoming call
The IP phone receives a voice mail
A call is muted
The IP phone is busy
The IP phone misses a call

Please login the phone and go to Features > Power LED tab

Hope this will help.

Kind regards,
Frank.

RE: T58A red light flashing
Hi complex1,

thank you, but unfortunately that doesn't change it:
I deacticated every option in the Power-LED-tab.

Afterwards the red LED still starts flashing as soon as the display gets dark.
It stops blinking when the screen is activated, and starts again as soon as screensaver/energy-saving turns off the display.

Hi,

Please auto-provision the phone with next parameters:
Code:
#!version:1.0.0.1
features.power_saving.power_led_flash.on_time = 0
features.power_saving.power_led_flash.off_time = 3000

Hope this will help.

Kind regards,
Frank.

RE: T58A red light flashing
Hello complex1,

thank you. This helped partly.
I have put these values into the T58 template file "common.cfg" and autoprovisioned it over FTP with a boot file.

Now the LED is not flashing anymore, but it is permanently on as soon as the screensaver gets dark. May I have made a mistake? Or are there other numeric values to either
a) turn the LED completely off
or b) let it flash more seldom, so with longer intervals between flashes?

Thank you in advance.

Strange, these settings should work. I use them too.

As you can read in the Admin Guide:
Code:
features.power_saving.power_led_flash.on_time
If it is set to 0 and “features.power_saving.power_led_flash.off_time” is not set to 0, the power LED indicator will be off when the phone enters the power-saving mode.
(Default: 500)

features.power_saving.power_led_flash.off_time
If it is set to 0, the power LED indicator will be on when the phone enters the power-saving mode.
(Default: 3000)

Please re-check your settings.

Kind regards,
Frank.

You are right: Accidently, I interchanged both values (0/3000), because in the Common.cfg template file, both entries are ordered differently, "off" is first entry followed by "on". My fault, I am sorry.

Now it works - thank you very much!
