On phones which is upgraded to this version, corporate directory is not working. Getting error "Host Not Found"

For the same model phone with firmware version SCCP458.5.2S, corporate directory is working fine.

Why the phone with SCCP459.2.1S corporate directory getting error "Host Not Found"

Cisco sw download shows SCCP459.2.1S is compatible with CUCM version 5.1.3.

Dear Alex

It works after deleting ITL file. Is it possible to erase this ITL file as a bulk? for all the selected phones?

Just to add to the excellent pointers already given by the great Alex! and the ever reliable Ronak. You can check the ff:

1. is your server defined by hostname, i.e in cucm system>server. If this is so you can try and do this; change under System > Server, the hostname to an IP address there, save it, then restart th Trust Verification Service (TVS).

We had a similar problem fixed like this yesterday. You can verify this by downloading the configuration file of the phone

tftp -i get SEP0000DEADBEEF.cnf.xml

change to your cucm ip address, and sep00000..to one of the 7942 phone mac address.

To enable tftp client do this

open Control Panel > Programs and Features > click Turn Windows features on or off in left side > enable  Client TFTP then click in OK

Check for the TVS entry you should see something like this..


cur1sr07------------If your address is defined by hostname then here is the problem.

You can resolve this by either changing your server to ip as I mentioned or add DNS address to the phone that can resolve the server name
