[cisco-voip] Temp Fail message on phones

[CarlosOrtiz at bayviewfinancial.com]

In the archives someone mentioned bad DSP's on the phone.  How many phones 
did you return and what type were they 60,61 etc?  Your whole batch was 
bad? Were your phones in production for a while before it happened or did 
it occur right away?  I am trying to see how close I am to your scenario.

RE: [cisco-voip] Temp Fail message on phones






Client of ours came across this issue for a batch of phones last year. 
Performed a factory reset, moved the phones off to a different switch 
port, moved them to a completely different switch, upgraded the firmware, 
swapped out the patch cables, checked call statistics for lost packets….. 
As for codec mismatches or unregistration events, CCM traces didn’t show 
any codec mismatches (no transcoders invoked) or  gateway unregistration 
events or d-channel flaps during the time the problem occurred. SCCP and 
Q931 signaling showed the disconnect was issued from the end user, not 
PSTN. Eventually opened a TAC case and was told it was due to hardware 
failure. Client RMA’ed the IP phones and never encountered the issue 
again.
 
Hope this helps.

Started seeing this error message last week at a remote location connected 
via MPLS on several phones intermittently.    People are actually on a 
phone call and get disconnected when the message appears.  After searching 
the archives it looks like there are multiple possibilites for the cause 
of this message: Packet loss, DSP issues, Codec mismatch, MGCP gateways 
unregistering, etc. 

Anyone have a clue what the likely cause would be when you have an H.323 
gateway and calls are already connected but get dropped in the middle?
