We recently received some new 7942 phones and had some issues getting them to work. We discovered we needed to upgrade our Callmanager version, and add the latest device pack. We have done both of these and are currently running as follows:
Cisco Callmanager version: 4.1(3)
Device Pack: ciscocm.4-1-DevPack-78
The device defaults are set to use SCCP42.8-3-5S for the 7942 phones. When first connected, the phones appear to upgrade via tftp with no problem, then reboot. Then the error: Registration Rejected: ErrorDBCo... appears.
The Status Messages screen repeatedly scrolls the following:
<timestamp> No CTL Installed
<timestamp> File Not Found: CTLFile.tlv
In reading through some troubleshooting docs here, it was mentioned to check the .cnf.xml files on the server - however I have searched both our call managers (both house tftp for redundancy) and neither seems to have any of these files.
The TFTP paths on both are quite full of what I am sure are old and outdated configs - but these systems were installed long before I arrived here so I am loathe to clean them up.
Any help in getting these phones up and running would be appreciated.
I would also like some recommendations on proper configuration of our phone cluster. We are small - with only about 300 phones. 2 Call Managers, one publisher, one subscriber. Both run TFTP. DHCP is handled by our domain controllers. Should we have one central location for TFTP?
I would schedule a time to give this a try. There is a need to reboot when adding support for a "new" device type;
NOTE: Apply this patch to all of your Cisco CallManager servers, beginning with the publisher server and TFTP server.
**When applying this Device Package to enable new device support, a cluster-wide reboot is required for those devices to register successfully. A clusterwide reboot IS NOT required when running to update existing firmware/support.
If installing on a Cisco Unified CallManager version earlier than 4.1(3)sr2, the following message will be displayed: âInstall on all nodes is required. All nodes will be rebooted as part of the installation.â
If installing on Cisco Unified CallManager 4.1(3)sr2 (recommended), the following message will be displayed: "Install on Publisher and TFTP server is required. Installation on all nodes is highly recommended." A clusterwide install/reboot is required.
From these older Device Pack Notes (this would be for your DevPak as well :)
Hope this helps!
