I have 2 vvx500 phones. Regardless of which speed / duplex mode I chose, the phones always connect at 10 meg full. I have a few vvx400s phone and they connect at whatever speed / duplex I set or connect at 100 /full in auto.
It's not a switch issue or cabling issue. The problem follows the phones.
It is always useful to include the currently used software version as issues experienced may already be addressed in a newer release.
This also allows yourself and others to check against current software release notes.
Therefore the Polycom VoIP FAQ contains this post here:
Question: How can I find out my SIP UC Software Version or the BootROM Version of my Phone? Resolution: Please check here
The only difference I could think of is that the VVX500 has a gigabit Ethernet port and the VVX400 only has a 100Mbit.
What switch are you using for this?
