console cable for cisco ip phone

Unanswered Question
Nov 22nd, 2008

Cisco 7940 ip phone:

there's a port on the base of this phone labeled RS232, it's for A 6PIN RJ-11 male plug. I'm having great difficulty getting the console cable for this port so I've decided to make one myself. I'm assuming the other end of the cable is a DB9 serial connector, is that correct?

Does anyone know the pinout config for this cable?

Does anyone know the correct name or part number for this cable?

thanks for any help.
