Description (partial)

This is an enhancement request.

In earlier releases, Jabber for desktop has these multiline limitations:

CTI-enabled users can only control the primary line on their desk phone.

You couldn't configure two lines with the same number that are associated with different partitions.
As of Release 12.7 and higher, users can control and select different lines on their desk phone. You can also configure two lines with the same number that are associated with different partitions.

However on the phones there is a parameter call "Always Use Prime Line", if you manually select a second line using the new Jabber feature, the line the user selects will make the call, ignoring the "always use prime line" on the device, a manual selection inside Jabber has greater priority than the option of "always use prime line".


1. Desk-phone is configured with these two settings - Always Use Prime Line and Always Use Prime Line for Voice Message (configuration page of the device in CM).

2. If you use the desk-phone on its own the two settings are working as expected.

3. If Jabber 12.7 takes control of the desk-phone and selects a second line, then the "always use prime line" option is overridden.

4. This happens on Jabber 12.7 and higher.

7. So when the end user selects the second line and make outbound calls - the call is not passing through the Prime Line, instead it will pass on the line the user selected.
