Still not available yet. Currently, it is on tap for the 10.5 release in Q3 2014.

The multiline support will provide the ability to control the second line. Currently, only the designated primary line can be controlled.Thanks,Don

The Jabber client doesn't have support for multi-line yet.Thanks,Don

Yes you can. You would only need Enhanced Plus license if you wanted to add softphone capability to Jabber, extend Jabber voice and video to a mobile device or have a second deskphone.http://www.cisco.com/en/US/docs/voice_ip_comm/jabber/Windows/9_1/J...

IP Communicator requires an Enhanced license.SPA should be essential for each port on the device.Thanks,Don
