Hi Tom, something similar has happened to me with Cisco ATA186 and a Cisco Switch module, with the ATA equipment that "disappears" every minute... ;( I've solved the problem setting explicitely speed & duplex type in switch port configuration. By default configuration it was in "auto". After setting 100Mb/full_duplex the problem has vanished and everithing is going well...

Re: [Asterisk-Users] Problem with Cisco phone
Unfortunately, I think you're right. It's a good thing you only have to reboot the phones for config and firmware changes. Omar A.

Valid values are Hub/Switch and PC. Default is Hub/Switch. Note If the value is PC, port 2 can be connected only to a PC. If you are not sure about the connection, use the Hub/Switch default value. Specifying the PC option and then connecting port 2 to a switch results in spanning-tree loops and network confusion.
