8851 and Bluetooth hand free

We just installed the latest 10.5.2 device pack(14082-1) and I am noticing I am unable to turn on Hands free 2 way audio.  I see the 8851 on my phone but it is unable to pair.

Any one else seeing this?

Thanks

Jason

Hi Jason,

Hi Jason,

Hi Jason,

Hi Jason,

I do not see any known bug for this issue related to these cucm and IP phone firmware versions. Try downgrading the phone firmware and see if the issue is resolved. If yes, then you may engage TAC to see if this could be a new bug or get some troubleshooting assistance.

I did not see a bug for it

I did not see a bug for it either.  I downgraded the code to sip88xx.10-3-1-20 and was able to pair my phone successfully.  Upgraded it back to sip88xx.11-5-1-18 and I am unable to turn on 2 way hands free..

Thanks

Hi there

 

 

Did you hit the Applications button >>  Bluetooth settings >>  "Hands-free 2-way audio" to ON

 

 

If not please share the firmware version on the phone, will dig out more and let you know

 

Hope this Helps

Cheers
Rath!

Re: 8851 and Bluetooth hand free

"Hands-free 2-way audio" "on" is dimmed, and causes no action.

Active load: sip88xx.12-1-1-12

Re: 8851 and Bluetooth hand free

Hi there

 

I think in your case its the same for both Session and Enhanced mode. right.


Could you try upgrading the phone firmware to 12.1(1)SR1 or downgrading back to 11.7(1).

 

If that resolves with 11.7 and still you want to keep your phone firmware with 12.X your best bet is get a hotfix from Cisco TAC.

 

Let me know how it goes,

 

Hope this Helps

Cheers
Rath!
