Hi Guys,
I need some help with the following problem involving our Cisco 7925g VOIP Phones.
The symptoms of our problem
- The 7925g phone functions perfectly with good voice quality, no one direction calls and no really roaming problems whilst it is active and operating in normal mode
- After an undefined period of time (anything from 20 minutes to 5 hours) the phone’s screen goes black and freezes.
- The phones power button does not function at this stage and requires the battery to be removed and before the phone will restart. No matter how long you wait, have even left the phone alone for a few days, the phone will not restart without removing the battery.
- We are experience identical symptoms on all our 7925g phones and at all our Branches, while the branch have same Access Controllers and Access Points they do have differently configuration Wireless Service Security and Authentication Settings.
- We have even tested a 7925g phone on a completely open SSID with no encrpytion and the phone still experiences the same problems.
We presume from the symptoms and the diagstonics log obtained from one of the phones, that the problems seems to caused by the memory being full. Any ideas if we are on the right track?

We also use the Cisco 7921g on this wireless infrastruture and this model seems to be working perfectly.
We have also updated the firmware of the 7925g to the latest version 1.4.3
Access Controller:
Model: H3C WX5002
Software Version: 2308P11 (Latest Release)
Access Points: WA2612-AGN and WA2220-AG
We have logged a support case with the H3C Support Technicians as well, but since all other devices include the Cisco 7921g phone work perfectly, they are battling to find a solution for us.
Any help in this regard will be greatly appreciated, as currently I have run out of ideas.
Many Thanks,
Brett
