[rescue] Looking for a few used cisco 7940 phones

[Robert Darlington]

I was under the impression that the g models were the ones that follow
the spec everyone else does for PoE and also talk SIP out of the box.
My 7960 (non-g) had to have the firmware updated to support SIP
instead of their old proprietary protocol.
