[cisco-voip] 7941G-GE IP Phone issues

[dschulz]

If you are not getting to the point where the phones are powering up, then I
would check the power status on the display.  I have not seen this between
different switches, but maybe it is marginal on the power (where the other
models work fine).  Do you have a different switch you can try it with?  In
the switch, check what power is actually being put out to the phone.  I
assume you checked the cabling.  It should power up and get to the screen to
look for registration (at least), without seeing a load from CM (assuming
that it didn't attempt to load a code that is a problem).  HTH,

Hi,

 

I just received 5 new 7941G-GE which are gigabit IP Phones.  I am using CM
4.1(3)sr2.  When I connect them to my 3560-PoE switch they power on, but
there is no display on the screens.  I haven't tried to connect them to a
gigabit switch yet, since I am going to upgrade later this year.  Only the
speaker button is lit and after about 8 seconds the extension lights flash
briefly.  This happens on all 5 phones I have tried to connect.  I currently
have 7941 phones and they work without any issues.  I have worked with Cisco
and they cannot seem to find any issues.  I was guessing it was a firmware
issue, but I cannot go through the phone settings due to no screen to see
what version of firmware or what TFTP server it is looking for.  The
firmware that is in my Device Defaults is "SCCP41.8-3-3S" which is the same
for 7941, 7961 and 7961G-GE models.  If anyone knows how to solve this it
would be greatly appreciated.

 

Thanks,
