Hi Anas,

Have u uploaded QED for this firmware on Call manager ? there is a bug associated with this firmware  which could be the cause of problem

9.4(1) QED and locales check in for 3905 phone

CSCuh23600

Description

Symptom:
The purpose of this check in is to add the 9.4(1) firmware and the related support files for Cisco IP Phone model 3905 to supported CUCM branchesConditions:
ccm 10.0Workaround:
none

But surprisingly I am asking you but not able to find QED for 9.4(1) on cisco site.

Can u try degrading fimrware to 9.2(2) since enabler is available for this firmware and check?

regds,

aman

Hi Amman,

I use the QED 9.2(1) when I enable the phone on CUCM 8. then I upload firmware 9.2(1). I register the phones on this version.

after that I did the upgrade to firmware version 9.4(1), I will try to downgrade and check

this is issue is really weird.

thanks

Hi Anas,

There would be  a separate QED for SIP 3905 9.4(1) which I am also not able to locate on Cisco site.

Try degrading to 9.2(1) and check the registration/provisioning issue.

I'm having the same issue but using CUCM 10.5 with Cisco 3905 phones.

Fail to register the phone in all three firmwares (9.2.1, 9.2.2 and 9.4.4) with QEDs (expect for 9.4.1). It gets stuck in provisionig and registering states.

Hello,

I have the same issue with the 3905 flapping between Registered and Provisioning

CUCM Version: 8.6.2.25900-8

3905 Firmware: CP3905.9-4-1SR2-2

What could be causing this issue?
