Problems with Wireless Hookswitch setting on CP-8841

[hh25318]

CUCM 11.0.1.21900-11 (cannot upgrade at this time)

The phone's settings are:

The Phone is CP-8841 with Active Load: sip88xx.12-5-1-16
The Headset is Jabra Engage 65 (have tried another headset)
The Link cable is Jabra Link 14201-22 (have tried another cable)
Have factory reset the phone as per this guidance

Other CP-8841s working fine.
Is there a way to view whether the Wireless Hookswitch setting has actually been passed to the phone?

All suggestions welcome...

It should be in the configuration file for the phone, under <vendorConfig> you should see <ehookEnable> which is 0 for off, and 1 for on.

Release 12.7 added a setting in the Admin Settings menu to enable this on the phone itself under "Aux Port", but, I'm afraid I haven't tested this to see if the check mark implies the functionality is enabled or not, since it sort of switches the default from off to on by it being there.

I note you're on 12.5 so that isn't relevant just yet for you.

If the aux port is working and it's not currently set as console then that should be it. You can verify in the tftp configuration file for the phone that the setting from the UCM has made it that far.

Thank you so much. That was very helpful.
So the config file on the UCM for the phone says: <ehookEnable>1</ehookEnable>
So now at least I know that the UCM config file (phonename..cnf.xml.sgn) is correct. 
(For anyone reading this, I used this link to guide me)

Two thoughts... 
1. Is it possible to confirm that the config file is on the phone and ensure it's correct?
2. You said "and it's not currently set as console". What does this refer to?

[Adam Pawlowski]

I would typically just look at the phone status messages.

If the phone has a trust issue and won't update its ITL/CTL, it will not verify the configuration and will ignore it.

You did say you'd factory reset the phone.

Console access is a device setting as well.

I don't know if that has to be disabled for wireless hookswitch control to work.

There is a chance that the Aux port doesn't work on the device I suppose.

Our organization also uses the Jabra Engage 65 headsets with 7900 and 8800 series Cisco phones. We use a different LINK cable for wireless Hookswitch control though. It sounds like you have that cable working with a different 8800, but the 14201-22 Jabra LINK cable is rated for use with the 7900 series, not 8800 (https://www.jabra.com/accessories/jabra-link-14201-22##14201-22). The cable that we use for the 8800 series phones is the Jabra LINK 14201-43 (https://www.jabra.com/accessories/jabra-link-14201-43##14201-43).

Hope that helps.
