[Freeswitch-users] Cisco 7940 To Private

I have some Cisco 7940's registered and working well with FS, but whenever I dial out from the Cisco phone, it indicates the call is "To Private" rather than showing the number I'm calling or something. I've put the SIP trace in pastebin http://pastebin.freeswitch.org/12589 - there is a Remote-Part-ID field that seems OK. Does anyone know what Cisco is looking for here? Thanks, Troy
