User cannot connect on phone with extension mobility

[kseewald]

Dear experts,

we have IP Communicator with Extension mobility. Application Login/logout is working fine.

User can Login with his Profile on any Workstation.

only one PC with IP Communicator brings error when loggin in "Login ist nicht verfügbar (11)"  (it´s german - Translation is "Login is not available (11)"

it happens with any user account.

when typing in an unknown accout we get back the message "Login erneut versuchen (201)"  - " Login try again (201)" .

The link the phone is trying to reach is same like from any Communicator which is working fine.

http://10.10.60.100:8080/emapp/EMAppServlet?device=SEP64006a836bd6&seq=1234&userid=testwd

we did two  wireshark from a Comm where the Login is fine and the one which is not fine.

I can´t figure out of these, where the Problem Comes from  (see attached files)

Need help

Best Regards,

Klaus

Extension Mobility is not enabled on that CIPC device. This is a checkbox on the Device Configuration page.

Hi, The Checkbox was definitely set .

Do you have Web Proxy configured on the PC where the non-working CIPC is? Try bypassing CUCM IP Address/LAN IP Address
