Got an issue with corporate directory. Suddenly all the cisco phones of one of our customer cannot access corporate directory and it says Host not found.
CUCm Ver : 10.5
Phones : 8945
Read all the blogs / docs in support community and checked the TVS certificates and also entered the secured login URL on the phones but it didn't make any change.
Factory reset the phone but still same issue.
Can anyone guide me the right path to check this issue.
check your LDAP directory settings:
System > LDAP > LDAP Directory
make sure the user ID that you use for this, still has sufficient permissions
Please rate if usefull
Thankyou all for your replies.
Certification is fine and it expires in 2019.
No changes done in LDAP user permission. Corporate directory was working before and suddenly stops working.
Tried to view console logs but it doesn't show anything related to Corporate directory or Host not found
I found a weird thing. When I assign the phone to register with publisher the corporate directory works. is there something I can check.
Can anyone help !!.
Can you check the replication ?
The publisher and the subscriber are on the same LAN addresses?
What are the chances that your cluster is configured with a domain name, and your servers configurations (System -> Servers) are configured with FQDN? if so, your phones also will try to locate the Corporate Directory via the FQDN. So if that's really the case, you might have a networking / DNS resolving issue. Please check that this customer has a DNS servers configured (or given by DHCP) and a domain name on his phone.
Recreate the issue and collect Phone console logs.
