We deployed Cisco IP telephony in our office and during use we`ve founded that SW port in IP Phone which is interconnected with Cisco Catalyst 2924
(all ports are "auto" for speed and duplex)
And as I know port in IP phone also using "auto"
But in reality the switched ports _alvays_ connect in halfduplex - 100Mb, why it is so?
The answer "defind speed and duplex manualy" is not I`m looking for, as I suppose autonegotiation MUST work.
Or the situation I`m talking about is not a bug but feature?
