topic Hi Zolt,The RT phones need in Collaboration Applications

Jabber for Windows cannot control 8841 desk phone

Hello Team,

We have a problem with desktop phone control in case of 8841 phone.

When the user try to switch to the 8841 phone in Jabber then we got the following error message in the log:

2014-11-07 09:39:53,855 ERROR [0x00000298] [ice\TelephonyAdapterPhoneDevice.cpp(178)] [TelephonyAdapter] [TelephonyAdapter::selectDeviceImpl] - switchMode to device [SEP84802D7698D6] failed with error [eDeviceRegCouldNotOpenDevice]

We get the red X on the phone icon, and the desktop phone control is not working.

If the same user try to control 7940 phone, then it's working fine.

The environment: UCM 9.1.2.12901-3, CUPS 9.1.1.51900-5, Jabber for Windows 10-5.2

Edited:

Same issue with UCM 10.5.1, CUPS 10.5.1, and Jabber for Windows 10.5.2.

Zsolt

Standard CTI Allow Control of Phones supporting Rollover Mode

If they are not added, please add these permission.

After having same problem and reading this thread I did the following and it worked...

Associated the phone to the user

Added standard CTI, and the two 88xx groups (xfer/rollover)

Went to the users CSF and "Set Primary Phone" to the new 88xx (save/reset)

Went to the 88xx phone itself and made sure the DN was associated to the user

Went to the 88xx device itself and made the user was the owner

Reset the 88xx

Everything worked!

Thank you!

How did you manage to get the 8845's working?

Also has anyone been able to work this out if you have extension mobility enabled on 8845's?

Thanks!
