I have installed a Ip Phone 7936 in a cluster of call manager 4.3, and I have one problem into access to the corporate directory. The 7936 show me in the screen "server not found".
I used a LDAP of the Call Manager.
I create a user that controller this Phone.
The phone is functionally correctly except the access of Corporative Directory.
Somebody can hepl me?
Thanks for all.
I found this on CCO may be its related to the issue
This problem arises when the Corporate Directory in use is not the default Corporate Directory that ships with the Cisco Unified Communications Manager(CallManager). Cisco Unified IP Conference Station 7936 does not support Custom Corporate Directory. It only supports the default /CCMCIP/xmldirectory.asp.
Cisco Unified IP Conference Station 7936 does not support all XML tags listed in the IP Phone Services SDK. Also, it does not support the URLs and action tags used specifically by the ldapsearch.asp included with the Cisco IP Phone Services SDK.
In order to overcome this problem, in the Custom Corporate Directory, use the same XML format, script flow, HTML method and action as used by the default Corporate Directory that comes with Cisco Unified Communications Manager(CallManager).
Just curious did we run the exe for the new firmware ? or you downloaded zip file.
On the phone device page can you try putting the new phone load name and reset the phone.
do you see any error in event viewer-->application logs ? if yes let me know the event id
check a previous post.
Might be related to firmware or bug
