Registering a new CP-8811 Phones

[wof19900rem]

We received a bunch of new CP-8811 phones.  What is the best way to have these register with CUCM?  In the past when we got new phones they would register automatically.  This phone just indicates "Phone is registering" on the display.  The phone is set for DHCP.  Is it possible it is not completing the registration process because a valid configuration file is not available.  We have never had this model on our premises before.

Does your CUCM release supports those models??

If yes, assuming you're trying to use auto-registration, have you changed the auto-registration protocol to SIP??? Default is SCCP

If not auto-reg, have you properly configured the device in CUCM, and are you sure there is nothing in your network preventing communication?

Good question.  Now that you asked it.  I checked on the following.  See my attachments.  My interpretation is that we need to upgrade our system to a newer version to support this model.

See what elst I found  http://www.cisco.com/c/en/us/products/collateral/collaboration-endpoints/unified-ip-phone-8800-series/datasheet-c78-731637.html.

Correct, you need 10.5(2), and you should always be in the maintenance release for your version, I'm running 10.5.2.13900-12 with no DevPacks and I see that model listed.

How difficult is it to install the latest maintenance release?  Is it easy to do for someone who has never done it before?  There is resistance to do in on our end because there is a big picture plan to migrate the phones to the parent company's cluster.

If you mean just something like 10.5(2) to 10.5(2)SU1, it's fairly easy. The procedure for any upgrade will be the same, but between major releases, there might be other things that come into play.

All you have to do, is either upload the ISO to the VM, or use SFTP, and follow the wizard. All the other things I show, changes to the VM, disk size, other COP files, etc are because that's a refresh upgrade, not your case if you just want to patch to a SU.

I don't know about the big plan, but if they have access to someone who has hands on experience with CUCM, he can do this in a heartbeat.
