We are currently evaluating a Cisco IP Phone, model 7961G-GE. A nice feature of this device is that it lets you run both a PC and the phone through the same ethernet line. However, we are running into issues with the phone not negotiating speeds properly on the line. Both the SW and PC ports are set to auto-negotiate in the phone settings, however only the PC port negotiates correctly. All of our networking equipment supports gigabit connections, and the PC port negotiates to gigabit speed, but the SW port always negotiates to 100 megabit speed. If I forceably set both the PC and SW ports to gigabit speed, the phone drops the connection and cannot seem to communicate any more. I have tested this on a POE switch as well as on a non-POE switch (with the phone running on external power) and noticed the same behavior both times. Any ideas on how we can get this working properly are much appreciated.
Thanks in advance,
