Nortel recommends that autonegotiate mode is used on the network and the IP
Phone. Use Full Duplex mode only when the network is forced Full Duplex for
100BT Full Duplex mode; otherwise, a duplex mismatch results.
If the IP Phone connects to a network configured for Full Duplex mode
only, the IP Phone cannot automatically negotiate the proper configuration.
Therefore, in this instance, to allow the IP Phone to work at the optimum
speed and duplex mode, Full Duplex mode must be enabled.
Use
