I look registration rejected on ipphone and the CCM version 4.1 not appear in device default, what can I do?

Correct Answer by migilles about 9 years 8 months ago

Will need to install this devpack either via VNC or at the computer console itself as via remote desktop connection is not supported.

Install the devpack on all servers in the cluster then reboot each of them. Upgrade the publisher first.

Make sure on the controller that you are using the setting for the newer version of admission control for 7920/7921 phones.

Give me the details. Access Points used, Wireless LAN Controller used, version of code on the WLC, phone that is used. The setting I was talking about earlier is on a Cisco wireless lan controller.

We don't officially support 3rd party AP solutions, but "should" work fine w/ some caveats. So would be best effort support. Not sure if Symbol supports WMM, etc.

the WLAN controller support Wi-Fi multimedia extensions like WMM-power save with admission control and the net is with access port

Registration rejected is not a WLAN issue.

Should be able to verify this by pinging the phone. So if you are not able to configure a 7921 in your CM, then you need to load the devpack.

I download the cmterm-7921-sccp.1-0-1.exe on the CCM (TFTP server), but the phone no appear on the device defaults, the w-iphone receive ip, from the callmanager I can do ping to the phone, and validate the TFTP in form manual on the w-ipohone

That is not the correct file. That is only 7921 firmware. That doesn't enable 7921 support on the CallManager.

See my previous posting tellnig you to install the CM devpack.

So yes if you can ping the CM, then not a WLAAN issue.

Install the devpack and you should be good.

This has nothing to do with the WLAN side, but has to do w/ the CallManager side.

If you don't see 7921 in device defaults, then you don't have support for 7921 and will need to load the latest devpack to enable support. Minimum supported version is 4.1(3) but will need to add the latest devpack (ciscocm.4-1-DevPack-56.exe).

I am bailing out on this one as it is not a WLAN issue at all.

I do have exactly the same issue. I' m running CCM 4.1(3). Altough I installed the latest Device Pack4.1(59) and the latest firmware 1.0(4) I can't see the 7921 at Device Defaults.

Did you get an response from TAC?

Or does anybody has a solution for this?

Hi Peter,

Did you follow the steps outlined in this doc?

Must have at least CCM 4.1.3SR1


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: “Install on all nodes is required. All nodes will be rebooted as part of the installation.”

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.

Perform the following procedure to install Cisco Unified CallManager Device Package X.X.exe:

1. Download the ciscocm-4-1-DevPack-X.X.exe file to your hard drive. Make a note of the location where you saved the file.

2. Double-click on the downloaded file to begin the installation.

3. Click Yes when the installation process displays a message that asks if you want to install this Device Package.

4. The remainder of the installation process continues without any additional user input.

5. Towards the end of the install it will prompt you "Update ALL devices firmware defaults?", (IMPORTANT) If you click "yes", it will change the default firmware load for all devices to the latest load packaged with this device pack, click "no" if you want to change the loads manually yourself later.

Note: In order to change the loads manually, you do NOT need to reinstall this Device Package. The new files will be present in the C:\Program Files\Cisco\TFTPPath folder. Go to CCMAdmin->System->Device Defaults and manually change the name of the load file (for specific device(s)) to the new load and click UPDATE. Next, reset the affected devices for them to upgrade to the new load.

The system will ask you if you want to view the logfile when the installation is complete.

6. Verify that the installation completed successfully by taking the following actions:

a. When the system prompts you to view the log file, if the number of errors listed in the dialog is "0", you can select No.

b. If the number of errors detected was greater than 0, select Yes to view the logfile and scroll down to the end of the log file. The errors section at the bottom of the log file will be updated with a corresponding severity.

c. Reset affected devices in order for them to obtain new firmware loads, or reboot the cluster.

Note: If the TFTP server is a separate server from the Publisher, the Cisco TFTP service needs to be stopped and restarted on the TFTP server before performing this step, unless the cluster (including the TFTP server) is being rebooted.

From this good readme for the device pack;


Hope this helps!
