Cisco 7942 does not boot - only speaker LED is on

Hi,

I have a Cisco 7942 phone which is not booting.

After connecting the PoE network cable to the phone these buttons are on

- mailbox (at the handset), both line buttons, headset, mute, speaker

Then all these buttons goes off and only the speaker LED is on and in the display nothing is displayed.

I already tried to make a factory reset which is not working.

What can I do to make this Cisco 7942 working again?

Hello Michael,

My friend also suggest me to perform RMA with Cisco because he has same exprience before with 20+ new phone in problem. But in my case, because my phones were expired maintenance, I've no way to apply RMA.


BTW, I'm going to build up a CME for try another call manager for last chance. Will update you the result here and see if I'm luck.

Best regards,

Rudolf

how to bypass speaker light.

 

  1. Press the # key and plug the phone back in.
  2. When you see the MUTE light turn on (RED) and soon Speaker turn on (GREEN) then you need Tap on Speaker light 3 times or more until you see the top lights Start flashing and key in the sequence 123456789*0# to reset the phone.
