So my wife's employeer gave her this VoIP phone to use while WFH, I just realized that it has a USB port which I tried to connect stuff to and nothing seems to work, not even charging. While messing around (since he employeer is a cheap MF) to find a better solution for the headset she was given, I tried to connect the USB dongle for my Jabra headset, that does not seem to do anything either. Checking online I found that this CP model seem to have a BLUETOOTH OPTION?? What? so I tried messing around with the configuration and I could not find any bluetooth configation option, or anything even related (I'm a computer engineer so I trust me that the option is just missing).

So, here is where I hope to get help, I'm wondering if her employee IT dep has just straigh up blocked/removed some options (the phone options seem rather basic for a +$200 VoIP phone), wanted to straigh up reset it and see what happens, but I don't want to cause her any troubles, so I have a few very specific questions:
* Would it even be possible to disable bluetooth? And say wallpaper options (that option is there, but there are no walpapers to choose from for example, not that I care about the walpaper though)

* Does the CP-8851 comes wityh bluetooth by default? There is nothing else to be purchased? Could this be model without the bluetooth?
* What does the USB work with? Could that be blocked by admin too?

If the BLE option is grayed out, the admin has disabled BLE from the CUCM. If the BLE option is not even present, the phone is, most likely, loaded with early release firmware that does not support BLE.

CUCM stands for Cisco Unified Call Manager. It is a server that manages the phone and decodes voice traffic, from analogue to IP, and back. It is an extremely expensive series of servers and requires a small army of talented people to maintain, operate, configure and troubleshoot.

If the IT dept is not the sharpest pencil in the base, then there is no hope. The worst case scenario I have singing in my head is the CUCM server is running a really old software, possibly one with known software vulnerability. Because upgrading CUCM, or even upgrading the device pack, requires skills.

Would it be possible to upgrade CUCM? I know for a fact that they IT dep won't help any further... I don't really care if the phone stop working, she can just play dumb and say we had lightning or something.. IT dep is not the smartest either...

For consistency, all phones in the location must be provisioned precisely the same way, in this case being the Cisco 8851. The client must also select between 4 parking spots (up to 12 phones per site), or three parking spots (up to 16 phones per location).

Can you pair the hearing aids directly to your mobile phone via blue tooth. Nowadays, most hearing aids could be connected directly to the HA. You will then receive all the calls thru the mobile phone. Loud and clear.

The document from phonakpro that rothlev1 posted seems to show a Roger Select as their solution to connecting to call system phone systems. However the Select is only a Class 2 device with short range although it might do a better job of transmitting your voice than the hearing aid microphones.

I use the Cisco 8851 Bluetooth landline phone. Very poor reception. Phonak recommend the ROGER NECK LOOP. I ALSO have the roger on. Can the neckloop connect to the landline phone the connect to my hearing aids? What is the set up so i can hear better and be wireless at work ??

I have worked with RingCentral for hours on this and as we all know speed dials have been around for over 20 years on traditional PBX systems. All of RingCentral's competitors including 8x8 and Zoom offer speed dials on the Cisco 8851 phones. I still can not get anyone to show me how to add a speed dial to my Cisco 8851 phone I purchased from RingCentral. Does anyone know how to do this. Speed dials are probably the most important feature to a desk phone for businesses and I do not see any reason this will not work, that is like selling me a car without a steering wheel its useless. Can someone please show me how to add a simple speed dial to this Cisco 8851 phone.

Thank you,

Set up speed-dial codes in the Self Care portal. Cisco VoIP - Setting speed dials on your telephone in the Self Care Portal If you do not have access to the Self Care portal, please have your authorized user place a Change request to add speed dials. Cisco VoIP Request Forms

The first button is always for the primary line of the phone and cannot be used for speed dials. Additional lines on your phone may occupy other speed dial buttons. You can see only as many speed-dial numbers as you have available speed dial buttons For example, you add 15 speed dial numbers in the Self Care portal but your phone has four available speed dial buttons. You will only be able to see the first four speed dial numbers from the list of speed-dial numbers on your telephone. To see the other speed dial numbers, please follow the instructions below.

You can buy an expansion module (also known as a sidecar) to display more speed dials on the 8851. These expansion modules can be purchased at Shop@UW. By default, the 8851 reserves the 5 right speed dial buttons for other features. If you would like to use these buttons for speed dials, please have your authorized user fill out a Change Request. Cisco VoIP Request Forms

The speed dials that you set up in the Self Care portal are simply speed dials. Cisco also supports a feature called Busy Lamp Field (BLF). A BLF button works as a speed dial but it will also let you know if that line is in use. This feature cannot be set up by a user; only administrators can set this up. If you are interested in this feature, please have your authorized user fill out a Change Request. Cisco VoIP Request Forms
