DO you have in your Enterprise Parameters the URL using thr FQDN of the CCM or the IP address? Switch to IP address to rule out DNS, also try a IISRESET from the command line of the server where the directory is homed too.
I use IP addresses. When it happens to individual phones, I simply reset the phones and it's fine. I was just wondering why it was happening in the first place. Nothing has changed on the network, I use IP addresses as opposed to DNS, and the servers haven't been down in nearly a year.
We are having the same problem. We are also running 4.1.3sr2 and when you look at the html page for the phone, you do not see anything listed for the directories. Some phones have it and others do not, even though they have the same TFTP and CCM servers.
got the same problem. I run 4.1.3sr4b. mine is even worse, "corporate directory" never shows up on IP phones.
I bounced my publisher and reset all of the devices in departments that were having the issues (my callmanagers have been up for over 9 months with no reboots). It has quit happening for the time being.
I was also running 4.1(3)sr4b and was having a problem with the Corporate Directory disappearing from random phones. You could either reset the phone in CCM or Do a **#** to reboot the phone and you'd get the directory back. I just upgraded to 4.1(3)sr4d and I'm going to upgrade to 4.1(3)ES94 next. We'll see if the problem ever comes back.
I guess I have. I patched up my callmanager, the OS, and loaded the latest devpack. I haven't had any issues since. It had been a very long time since I upgraded my callmanager.
