What is the difference between Device pack & Firmware load

[Siva Prasad Kakani]

We have purchased a new Phone with model: 7821. We have the CUCM version 8.6.2. As the phone model is not listed int the "Phone type" to Add the phones. I've verified and found the Device pack "cmterm-devicepack8.6.2.26149-1.cop.sgn" and Firmware load "
cmterm-78xx.10-2-1-12SR1-4.cop.sgn".

Could you please provide difference between them? Is it installing Firmware load suffice for adding the new phone mode: 7821?

Hi,

Device Pack will enable the phone to be added in the call manager.

firmware is the file installed in the phone itself.

Is that means both need to be installed on the CUCM?

Yes.  You install a device pack so you can select the phone as a phone type and then the firmware itself so that the phone can pull the load that it will be running.

No. If a device pack adds support for a new phone in CCMAdmin, it will also install the firmware to support the device too. You only need both the device pack AND firmware if there is a later firmware than is in the device pack.

Yeah, I was meaning to explain the differences between them not installing different firmware unless he was doing to push an upgrade.

Devices packs are a collection of the latest device firmwares available for CUCM. They will also add support for new devices.

Firmware loads are just updated firmware for a particular device.

Occasionally Cisco release a QED file which adds support for just one particular device to CUCM without the need for a device pack.
