HI all,
I would like to share with you following problems:
The problem we still have is that some 7925 phones get stuck with the display saying “Konfiguriere IP” sometimes, I believe it is related to the renewing of the IP with the DHCP server.
The only problem is that the phones sometimes lose their IP, so it’s only DHCP to look at. The phones are simple DHCP clients, the WLC is transparent for the DHCP.
here is config:
#
!
ip dhcp pool VOIP
network 172.25.0.0 255.255.0.0
default-router 172.25.0.1
dns-server 172.24.1.101 172.24.1.100
domain-name zamek.de
option 150 ip 172.25.0.21 172.25.0.20
lease 30
!
interface Vlan25
description VOIP
ip address 172.25.0.1 255.255.0.0
!
The phones also seem to recover after some time, so they don’t know that it happened. Unfortunately we don’t know which phone is when affected. We just changed the phones to b/g only and EAP-FAST but it seems that makes no difference.
Thank you for help:)

Are you using HREAP or local mode APs?
Do you have session timeout configured under the voice SSID? If yes, what ist he period that is configured?

If I click on Hreap groups I do not see any
Under WLANs H-Reap local switching and H-reap local auth is not enabled
Session Timout is not enabled
Thank you for help

7.0.220.0 should be fine, but recommend to go to 7.0.235.0.
There were some fixes in the 1.4(2) release for a phone side issue, but see you are running that already.
Suggest to use 1.4.3.4, which is the latest release.
What AP models are you using?
If using Cisco 11n AP & 5 GHz, then is best to use 1.4.3.4.
If it is occuring with multiple phones simultaneously, then would more than likely be an infrastructure issue not a local phone issue.
