Okay I finally got this 7940 set up, but from what I can tell I need to be able to set it up to use a stun server for the gizmo SIP phone service. I ran wireshark and made calls with the gizmo software and it deffinately uses stun. I have the newest firmware I could find on the phone and no stun settings, are you just not supposed to use stun with these phones? my firmware settings are
Application Load ID
P03-08-6-00
Boot Load ID
PC030301
DSP Load ID
4.0(2.0)[A0]
am I just hosed?
