I'm looking for some Cisco documentation or confirmation as to the pin out details for the headset wiring on a 7960G. The closest I have come so far is at this site, but I would just like some Cisco documentation to confirm.
All I can seem to find is the pin out details of the AUX and Ethernet ports. The only thing I have seen is the technical specification which actually says that the headset (and handset) port are RJ9, although the site above suggests RJ10 (an I belive the jack typ plug we have used) and Wikipedia suggests that these "RJ" definition don't actually exist.
Many thanks for this. In fact, its the same link as I added in my original post above. Whilst this was indeed the best I could find, I did wonder if there was a something from Cisco, or that a Cisco employee might be able to confirm.
The reason I am asking is that this pin out in the above article differs slightly to a pin out taken from a cable that was designed for us many, many years ago (circa 2000) but has worked perfectly well for all this time in multiple applications. The positive feeds are the same, but the negative returns are switched (i.e. we have Pin 1 --> Spk +ve, Pin 2 --> Spk -ve, Pin 3 --> Mic +ve, Pin 4 --> Mic -ve). It may well be that if the negatives are earthed to a common ground, then it might not make any difference - but I would just like to be sure.
