NOTE* Cisco IP Communicator and old SCCP IP desk phones such as the 7911, 7941, and 7961 devices will not have the ability to forward the second programmed line. Only New SIP devices such as Cisco Jabber, 7821, 8811, 8841, and the 8851 can.
This is how you forward the second line on Cisco Jabber:
Locate and Click on the icon at the bottom left of the jabber window, to the right of your name and extension. (Highlighted in Yellow in the picture)
A new window will pop up like the one pictured below.
Click on the drop down box under Forward Calls and select the line you want to forward and where you want it to forward to. Choose "New Number" to forward to a cell phone or a different telephone number. Use the EWU dialing rules to do so.
If you have any issues please contact the help desk at x2247 (509.359.2247).
