[cisco-voip] Problems with 7941 hookswitch

Tue Sep 19 10:03:13 EDT 2006

click here for more information about the self-destructing, ahem, I mean self-cleaning hookswitches ;)

i think that is their official answer:

to quote:
  A thorough analysis of a large number of Cisco IP Phones that have been reported as hardware failures has been completed and our research reveals that the great majority of these phones do not have any determinable failure. The standard by which the phone industry measures phone failures is based on Bell Corp/Telcordia standards and the standard acceptable failure rate is set at 4 percent. The Cisco IP Phone's overall failure rate is well under the acceptable industry average. Many of the problems that have been reported as hardware failures are really either operational or cleanup issues. This document describes some common troubleshoot steps to be taken before you attempt to replace the Cisco IP Phone.

we have over 7000 phones, so 4% is about 280 phones. not very pretty.

  We just started ordering these so that's not good to hear.  Only have about 15 7941 & 7961 deployed but no problems yet.  We do have 50+ on order for our next deployment though?  Is this being addressed formally by Cisco?????

  We're experiencing the same problems.  We just deployed 350 phones to our corporate headquarters and have had about 15 failures so far, so 5% sounds about right.  We didn't get maintenance on them either so we're happy to have them fail now rather than later, but it is really irritating.  It just creates a lot of extra work for us that we really didn't need.  Our were scattered between 41s and 61s as well.  

  We've also noticed that they seem to disconnect from the Ethernet jacks more often.  If people are moving their phones around, they have a tendency to jiggle loose and then reboot.  Again, never had that problem with the 40s or 60s but it seems pretty chronic with the 41s and 61s.

  Hi

  Is anyone else seeing a lot of 7941's with bad hookswitches? 

  We've had to RMA about 10 of them in the last month.  The switch pops up normally when the phone is taken off hook but the user doesn't get dial tone.  If you press the hookswitch 5 or 6 times eventually you get a tone but there's definately something not working right. 

  Just wondering.
