[cisco-voip] 7975 reset problem

Fri Sep 16 10:29:32 EDT 2011

Last=TCP-timeout

That seems pretty clear.  Phone tried to send a message to CUCM and never received TCP ACK.  Most likely over a poor network connection (wireless?).  Possibly this phone has geometric TCP enabled where others have it disabled?

CSCsm81227    Allow Geometric TCP phone failover to be configurable

This affects the rate and timing of TCP retries.

Subject: 7975 reset problem
To: cisco voip <cisco-voip at puck.nether.net>

Dears,

I have few 7975 IP Phones which reset by themselves randomly. They reside in an office which has a wireless connection to the Call Manager location. All other phones (7911, 7941 and 7962) in the same office don't exhibit the same problem. Could this be a firmware issue?

CM version      :   6.1.3.1000-16
Device firmware:  SCCP75.8-4-2S

best regards,

Abebe Amare
