Note

The CP860 IP conference phone has Internet port only. There are three optional methods

of transmission configuration for Internet port:

 Auto-negotiation

 Half-duplex

 Full-duplex

Auto-negotiation is configured for Internet port on the IP phone by default.

Auto-negotiation

Auto-negotiation means that all connected devices choose common transmission

parameters (e.g., speed and duplex mode) to transmit voice or data over Ethernet. This

process entails devices first sharing transmission capabilities and then selecting the

highest performance transmission mode supported by both. You can configure the

Internet port on IP phones to auto-negotiate during the transmission.

Half-duplex

Half-duplex transmission refers to transmitting voice or data in both directions, but in

one direction at a time; this means one device can send data on the line, but not

receive data simultaneously. You can configure the half-duplex transmission on Internet

port for IP phones to transmit in 10Mbps or 100Mbps.

Wrong network settings may result in inaccessibility of your phone and may also have an

impact on your network performance. For more information on these parameters,

contact your network administrator.
