[cisco-voip] 8865 + KEM + Video Calls

[Matthew Loraditch]

I have a feeling that’s for the new model. The BEKEM model existed long before 12.x did but you never know!

I just noticed that there is a requirement in the accessories guide to be running 12.0(1) firmware when using the KEM.

"The Cisco IP Phone 8851/8861 Key Expansion Module and the Cisco IP Phone 8865 Key Expansion Module require firmware release 12.0(1) or later, and Cisco Unified Communications Manager 10.5(2) or later to function."

And this phone is running 11.7(1).  Let me get that upgraded quick and re-test.

The module is the single LCD flat one, not the dual screen angled one.  The module in CUCM is listed as "BEKEM 36-Button Line Expansion Module" as opposed to "CP-8800-Video 28 Button Key Expansion Module" or even "CP-8800-Audio 28 Button Key Expansion Module"

Interestingly, I have both an 11.5(1)SU3 and an 11.5(1)SU4 deployment to look at, and the SU3 one doesn't have the newer KEM selections in the drop down, but the SU4 one does.  So, you would think that the SU4 Release Notes would mention it, but there's nothing in there.

I'd be surprised if the module itself is causing the phone to negotiate video or not, but I suppose Cisco does like to keep us on our toes.

The CP-BEKEM or the newer one? I’m speculating based on the way the newer one is listed as a video expansion module in some places you need the newer one..

I have a use case on an 8865 with the KEM, and a Line configured per the usual setup.  If that line is on the phone itself, I can call it, and get video to establish.  If I move the line to the KEM, I can call it, but get audio only.<https://facebook.com/heliontech>
 <https://facebook.com/heliontech>
Is that working as designed, a configuration miss on my part, or a defect?<https://facebook.com/heliontech>

Unfortunately, I don't have access to many expansion modules (none actually), so testing different setups/firmware versions is not possible.<https://facebook.com/heliontech>
